Key competitors are specifically focusing on Asia-Pacific and Middle-East & Africa regions, as they show strong tendency to adopt the general-purpose disk arrays in coming years.","materialsDescription":"<span style=\"font-weight: bold;\">What are the characteristics of storage?</span>\r\nStorage technologies at all levels of the storage hierarchy can be differentiated by evaluating certain core characteristics as well as measuring characteristics specific to a particular implementation. These core characteristics are volatility, mutability, accessibility, and addressability. For any particular implementation of any storage technology, the characteristics worth measuring are capacity and performance.\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Volatility</span></span>\r\nNon-volatile memory retains the stored information even if not constantly supplied with electric power. It is suitable for long-term storage of information. Volatile memory requires constant power to maintain the stored information. The fastest memory technologies are volatile ones, although that is not a universal rule. Since the primary storage is required to be very fast, it predominantly uses volatile memory.\r\nDynamic random-access memory is a form of volatile memory that also requires the stored information to be periodically reread and rewritten, or refreshed, otherwise it would vanish. Static random-access memory is a form of volatile memory similar to DRAM with the exception that it never needs to be refreshed as long as power is applied; it loses its content when the power supply is lost.\r\nAn uninterruptible power supply (UPS) can be used to give a computer a brief window of time to move information from primary volatile storage into non-volatile storage before the batteries are exhausted. Some systems, for example EMC Symmetrix, have integrated batteries that maintain volatile storage for several minutes.\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Mutability</span></span>\r\n<span style=\"font-weight: bold;\">Read/write storage or mutable storage</span>\r\n<div class=\"indent\">Allows information to be overwritten at any time. A computer without some amount of read/write storage for primary storage purposes would be useless for many tasks. Modern computers typically use read/write storage also for secondary storage.</div>\r\n<span style=\"font-weight: bold;\">Slow write, fast read storage</span>\r\n<div class=\"indent\">Read/write storage which allows information to be overwritten multiple times, but with the write operation being much slower than the read operation. Examples include CD-RW and SSD.</div>\r\n<span style=\"font-weight: bold;\">Write once storage</span>\r\n<div class=\"indent\">Write Once Read Many (WORM) allows the information to be written only once at some point after manufacture. Examples include semiconductor programmable read-only memory and CD-R.</div>\r\n<span style=\"font-weight: bold;\">Read only storage</span>\r\n<div class=\"indent\">Retains the information stored at the time of manufacture. Examples include mask ROM ICs and CD-ROM.</div>\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Accessibility</span></span>\r\n<span style=\"font-weight: bold;\">Random access</span>\r\n<div class=\"indent\">Any location in storage can be accessed at any moment in approximately the same amount of time. Such characteristic is well suited for primary and secondary storage. Most semiconductor memories and disk drives provide random access.</div>\r\n<span style=\"font-weight: bold;\">Sequential access</span>\r\n<div class=\"indent\">The accessing of pieces of information will be in a serial order, one after the other; therefore the time to access a particular piece of information depends upon which piece of information was last accessed. Such characteristic is typical of off-line storage.</div>\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Addressability</span></span>\r\n<span style=\"font-weight: bold;\">Location-addressable</span>\r\n<div class=\"indent\">Each individually accessible unit of information in storage is selected with its numerical memory address. In modern computers, location-addressable storage usually limits to primary storage, accessed internally by computer programs, since location-addressability is very efficient, but burdensome for humans.</div>\r\n<span style=\"font-weight: bold;\">File addressable</span>\r\n<div class=\"indent\">Information is divided into files of variable length, and a particular file is selected with human-readable directory and file names. The underlying device is still location-addressable, but the operating system of a computer provides the file system abstraction to make the operation more understandable. In modern computers, secondary, tertiary and off-line storage use file systems.</div>\r\n<span style=\"font-weight: bold;\">Content-addressable</span>\r\n<div class=\"indent\">Each individually accessible unit of information is selected based on the basis of (part of) the contents stored there. Content-addressable storage can be implemented using software (computer program) or hardware (computer device), with hardware being faster but more expensive option. Hardware content addressable memory is often used in a computer's CPU cache.</div>\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Capacity</span></span>\r\n<span style=\"font-weight: bold;\">Raw capacity</span>\r\n<div class=\"indent\">The total amount of stored information that a storage device or medium can hold. It is expressed as a quantity of bits or bytes (e.g. 10.4 megabytes).</div>\r\n<span style=\"font-weight: bold;\">Memory storage density</span>\r\n<div class=\"indent\">The compactness of stored information. It is the storage capacity of a medium divided with a unit of length, area or volume (e.g. 1.2 megabytes per square inch).</div>\r\n\r\n<span style=\"font-weight: bold;\"><span style=\"font-style: italic;\">Performance</span></span>\r\n<span style=\"font-weight: bold;\">Latency</span>\r\n<div class=\"indent\">The time it takes to access a particular location in storage. The relevant unit of measurement is typically nanosecond for primary storage, millisecond for secondary storage, and second for tertiary storage. It may make sense to separate read latency and write latency (especially for non-volatile memory[8]) and in case of sequential access storage, minimum, maximum and average latency.</div>\r\n<span style=\"font-weight: bold;\">Throughput</span>\r\n<div class=\"indent\">The rate at which information can be read from or written to the storage. In computer data storage, throughput is usually expressed in terms of megabytes per second (MB/s), though bit rate may also be used. As with latency, read rate and write rate may need to be differentiated. Also accessing media sequentially, as opposed to randomly, typically yields maximum throughput.</div>\r\n<span style=\"font-weight: bold;\">Granularity</span>\r\n<div class=\"indent\">The size of the largest "chunk" of data that can be efficiently accessed as a single unit, e.g. without introducing additional latency.</div>\r\n<span style=\"font-weight: bold;\">Reliability</span>\r\n<div class=\"indent\">The probability of spontaneous bit value change under various conditions, or overall failure rate.</div>\r\nUtilities such as hdparm and sar can be used to measure IO performance in Linux.\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Energy use</span></span>\r\n<ul><li>Storage devices that reduce fan usage, automatically shut-down during inactivity, and low power hard drives can reduce energy consumption by 90 percent.</li><li>2.5-inch hard disk drives often consume less power than larger ones. Low capacity solid-state drives have no moving parts and consume less power than hard disks. Also, memory may use more power than hard disks. Large caches, which are used to avoid hitting the memory wall, may also consume a large amount of power.</li></ul>\r\n\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Security</span></span>\r\nFull disk encryption, volume and virtual disk encryption, andor file/folder encryption is readily available for most storage devices.\r\nHardware memory encryption is available in Intel Architecture, supporting Total Memory Encryption (TME) and page granular memory encryption with multiple keys (MKTME) and in SPARC M7 generation since October 2015.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Storage_General_Purpose_Disk_Arrays.png","alias":"storage-general-purpose-disk-arrays"},"35":{"id":35,"title":"Server","description":"In computing, a server is a computer program or a device that provides functionality for other programs or devices, called "clients". This architecture is called the client–server model, and a single overall computation is distributed across multiple processes or devices. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients, or performing computation for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.\r\nClient–server systems are today most frequently implemented by (and often identified with) the request–response model: a client sends a request to the server, which performs some action and sends a response back to the client, typically with a result or acknowledgement. Designating a computer as "server-class hardware" implies that it is specialized for running servers on it. This often implies that it is more powerful and reliable than standard personal computers, but alternatively, large computing clusters may be composed of many relatively simple, replaceable server components.\r\nStrictly speaking, the term server refers to a computer program or process (running program). Through metonymy, it refers to a device used for (or a device dedicated to) running one or several server programs. On a network, such a device is called a host. In addition to server, the words serve and service (as noun and as verb) are frequently used, though servicer and servant are not. The word service (noun) may refer to either the abstract form of functionality, e.g. Web service. Alternatively, it may refer to a computer program that turns a computer into a server, e.g. Windows service. Originally used as "servers serve users" (and "users use servers"), in the sense of "obey", today one often says that "servers serve data", in the same sense as "give". For instance, web servers "serve web pages to users" or "service their requests".\r\nThe server is part of the client–server model; in this model, a server serves data for clients. The nature of communication between a client and server is request and response. This is in contrast with peer-to-peer model in which the relationship is on-demand reciprocation. In principle, any computerized process that can be used or called by another process (particularly remotely, particularly to share a resource) is a server, and the calling process or processes is a client. Thus any general purpose computer connected to a network can host servers. For example, if files on a device are shared by some process, that process is a file server. Similarly, web server software can run on any capable computer, and so a laptop or a personal computer can host a web server.\r\nWhile request–response is the most common client–server design, there are others, such as the publish–subscribe pattern. In the publish–subscribe pattern, clients register with a pub–sub server, subscribing to specified types of messages; this initial registration may be done by request–response. Thereafter, the pub–sub server forwards matching messages to the clients without any further requests: the server pushes messages to the client, rather than the client pulling messages from the server as in request–response.","materialsDescription":" <span style=\"font-weight: bold;\">What is a server?</span>\r\nA server is a software or hardware device that accepts and responds to requests made over a network. The device that makes the request, and receives a response from the server, is called a client. On the Internet, the term "server" commonly refers to the computer system which receives a request for a web document and sends the requested information to the client.\r\n<span style=\"font-weight: bold;\">What are they used for?</span>\r\nServers are used to manage network resources. For example, a user may set up a server to control access to a network, send/receive an e-mail, manage print jobs, or host a website. They are also proficient at performing intense calculations. Some servers are committed to a specific task, often referred to as dedicated. However, many servers today are shared servers which can take on the responsibility of e-mail, DNS, FTP, and even multiple websites in the case of a web server.\r\n<span style=\"font-weight: bold;\">Why are servers always on?</span>\r\nBecause they are commonly used to deliver services that are constantly required, most servers are never turned off. Consequently, when servers fail, they can cause the network users and company many problems. To alleviate these issues, servers are commonly set up to be fault-tolerant.\r\n<span style=\"font-weight: bold;\">What are the examples of servers?</span>\r\nThe following list contains links to various server types:\r\n<ul><li>Application server;</li><li>Blade server;</li><li>Cloud server;</li><li>Database server;</li><li>Dedicated server;</li><li>Domain name service;</li><li>File server;</li><li>Mail server;</li><li>Print server;</li><li>Proxy server;</li><li>Standalone server;</li><li>Web server.</li></ul>\r\n<span style=\"font-weight: bold;\">How do other computers connect to a server?</span>\r\nWith a local network, the server connects to a router or switch that all other computers on the network use. Once connected to the network, other computers can access that server and its features. For example, with a web server, a user could connect to the server to view a website, search, and communicate with other users on the network.\r\nAn Internet server works the same way as a local network server, but on a much larger scale. The server is assigned an IP address by InterNIC, or by a web host.\r\nUsually, users connect to a server using its domain name, which is registered with a domain name registrar. When users connect to the domain name (such as "computerhope.com"), the name is automatically translated to the server's IP address by a DNS resolver.\r\nThe domain name makes it easier for users to connect to the server because the name is easier to remember than an IP address. Also, domain names enable the server operator to change the IP address of the server without disrupting the way that users access the server. The domain name can always remain the same, even if the IP address changes.\r\n<span style=\"font-weight: bold;\">Where are servers stored?</span>\r\nIn a business or corporate environment, a server and other network equipment are often stored in a closet or glasshouse. These areas help isolate sensitive computers and equipment from people who should not have access to them.\r\nServers that are remote or not hosted on-site are located in a data center. With these types of servers, the hardware is managed by another company and configured remotely by you or your company.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Server.png","alias":"server"},"38":{"id":38,"title":"Tablet PC","description":"A tablet computer, commonly shortened to tablet, is a mobile device, typically with a mobile operating system and touchscreen display processing circuitry, and a rechargeable battery in a single, thin and flat package. Tablets, being computers, do what other personal computers do, but lack some input/output (I/O) abilities that others have. Modern tablets largely resemble modern smartphones, the only difference being that tablets are relatively larger than smartphones, with screens 7 inches (18 cm) or larger, measured diagonally, and may not support access to a cellular network.\r\nThe touchscreen display is operated by gestures executed by finger or digital pen (stylus), instead of the mouse, trackpad, and keyboard of larger computers. Portable computers can be classified according to the presence and appearance of physical keyboards. Two species of a tablet, the slate and booklet, do not have physical keyboards and usually accept text and other input by use of a virtual keyboard shown on their touchscreen displays. To compensate for their lack of a physical keyboard, most tablets can connect to independent physical keyboards by Bluetooth or USB; 2-in-1 PCs have keyboards, distinct from tablets.\r\nThe form of the tablet was conceptualized in the middle of the 20th century (Stanley Kubrick depicted fictional tablets in the 1968 science fiction film A Space Odyssey) and prototyped and developed in the last two decades of that century. In 2010, Apple released the iPad, the first mass-market tablet to achieve widespread popularity. Thereafter tablets rapidly rose in ubiquity and soon became a large product category used for personal, educational and workplace applications, with sales stabilizing in the mid-2010s.\r\nAndroid was the first of the 2000s-era dominating platforms for tablet computers to reach the market. In 2008, the first plans for Android-based tablets appeared. The first products were released in 2009. Among them was the Archos 5, a pocket-sized model with a 5-inch touchscreen, that was first released with a proprietary operating system and later (in 2009) released with Android 1.4. The Camangi WebStation was released in Q2 2009. The first LTE Android tablet appeared in late 2009 and was made by ICD for Verizon. This unit was called the Ultra, but a version called Vega was released around the same time. Ultra had a 7-inch display while Vega's was 15 inches. Many more products followed in 2010. Several manufacturers waited for Android Honeycomb, specifically adapted for use with tablets, which debuted in February 2011.\r\nApple is often credited for defining a new class of consumer device with the iPad, which shaped the commercial market for tablets in the following years, and was the most successful tablet at the time of its release. iPads and competing devices were tested by the US military in 2011 and cleared for secure use in 2013. Its debut in 2010 pushed tablets into the mainstream. Samsung's Galaxy Tab and others followed, continuing the trends towards the features listed above. In March 2012, PC Magazine reported that 31% of U.S. Internet users owned a tablet, used mainly for viewing published content such as video and news. The top-selling line of devices was Apple's iPad with 100 million sold between its release in April 2010 and mid-October 2012, but iPad market share (number of units) dropped to 36% in 2013 with Android tablets climbing to 62%. Android tablet sales volume was 121 million devices, plus 52 million, between 2012 and 2013 respectively. Individual brands of Android operating system devices or compatibles follow iPad with Amazon's Kindle Fire with 7 million, and Barnes & Noble's Nook with 5 million.\r\nThe BlackBerry PlayBook was announced in September 2010 that ran the BlackBerry Tablet OS. The BlackBerry PlayBook was officially released to US and Canadian consumers on April 19, 2011. Hewlett Packard announced that the TouchPad, running WebOS 3.0 on a 1.2 GHz Qualcomm Snapdragon CPU, would be released in June 2011. On August 18, 2011, HP announced the discontinuation of the TouchPad, due to sluggish sales.[66] In 2013, the Mozilla Foundation announced a prototype tablet model with Foxconn which ran on Firefox OS. Firefox OS was discontinued in 2016. The Canonical hinted that Ubuntu would be available on tablets by 2014. In February 2016 there was a commercial release of the BQ Aquaris Ubuntu tablet utilizing the Ubuntu Touch operating system. Canonical terminated support for the project due to lack of market interest on 5 April 2017 and it was then adopted by the UBports as a community project.\r\nAs of February 2014, 83% of mobile app developers were targeting tablets, but 93% of developers were targeting smartphones. By 2014 around 23% of B2B companies were said to have deployed tablets for sales-related activities, according to a survey report by Corporate Visions. The iPad held majority use in North America, Western Europe, Japan, Australia, and most of the Americas. Android tablets were more popular in most of Asia (China and Russia an exception), Africa and Eastern Europe. In 2015 tablet sales did not increase. Apple remained the largest seller but its market share declined below 25%. Samsung vice president Gary Riding said early in 2016 that tablets were only doing well among those using them for work. Newer models were more expensive and designed for a keyboard and stylus, which reflected the changing uses. As of early 2016, Android reigned over the market with 65%. Apple took the number 2 spot with 26%, and Windows took a distant third with the remaining 9%. In 2018, out of 4.4 billion computing devices, Android accounted for 2 billion, iOS for 1 billion, and the remainder were PCs, in various forms (desktop, notebook, or tablet), running various operating systems (Windows, macOS, ChromeOS, Linux, etc.).","materialsDescription":" <span style=\"font-weight: bold;\">Why are tablet PCs popular?</span>\r\nBy definition, a tablet is a highly portable PC whose primary interface is a touch screen that occupies the full length/width of the device but whose speaker and microphone are not positioned for hand-held calling. In popular perception, however, tablets simply combine the best aspects of smartphones and laptop PCs, creating what tablet lovers consider the ultimate mobile computing experience:\r\n<ul><li>Compatible with home/office wireless and cellular data networks</li><li>Portable, but with larger, clearer displays than earlier mobile devices</li><li>Powerful, but lighter and easier to carry than traditional laptops</li><li>Longer battery life and greater storage capacity than typical smartphones</li></ul>\r\nTablet owners can use touch commands or a virtual keyboard (sometimes a physical one) to run web browsers, email programs, and interactive games just like they do on a desktop PC or laptop. But when they're ready to move, they can keep working (or playing) simply by switching from a home/office wireless network to a cellular data network.\r\n<span style=\"font-weight: bold;\">Are there different types of tablet PCs?</span>\r\nYes and no, depending on the strictness of the definition.\r\nEngineers used the term slate to describe the original, widely popularized tablet PC form factor-- thin and flat, one-sided, without a keyboard. That distinguished tablets from convertibles: full-fledged, keyboard-equipped laptops with hinges that allowed the cover/touch screen to flip 180 degrees -- creating a bulky but usable "tablet."\r\nToday, the terminology has evolved -- adding the phrase "2-in-1" -- to better distinguish the different types of tablets and laptops. Note that within each category are models that run on mobile operating systems and others that run on regular PC operating systems:\r\n<ul><li><span style=\"font-weight: bold;\">Laptop:</span> The original, portable PC that opens partway, like a notebook, to reveal a screen and a keyboard.</li><li><span style=\"font-weight: bold;\">Tablet:</span> The original, widely popularized slate tablet form factor: thin, flat, and without a keyboard.</li><li><span style=\"font-weight: bold;\">2-in-1 Detachable</span> (also called a "hybrid laptop" or "hybrid tablet"): A device whose keyboard and screen can be fully detached from each other. Depending on the manufacturer, 2-in-1 Detachables might be marketed as "tablets-with-optional-keyboards" or "laptops-with-detachable-tablets."</li><li><span style=\"font-weight: bold;\">2-in-1 Attached</span> (also called a "convertible laptop" or "convertible tablet"): A device with either a hinge/screen combination that flips around for use as a tablet or a keyboard that in some way folds out from the screen/body. While similar to the original convertibles, today's 2-in-1 Attached models are much thinner and lighter.</li></ul>\r\nIn addition, a new term -- Multimode Tablet -- has emerged to describe models with specialized hinge/handles that allow them to be used traditionally (directly in your hands) or in multiple different ways while propped on a desktop (in tilt mode for easier touch entry (or to project the screen on a nearby wall), in standing mode for touch screen-controlled presentations, or in tent mode for less interactive presentations). Some pc manufacturers even offer a "hanging mode" or include "tablet mode" and "laptop mode" among their list of available modes.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Tablet_PC.png","alias":"tablet-pc"},"42":{"id":42,"title":"UTM - Unified threat management","description":"<span style=\"font-weight: bold; \">UTM (Unified Threat Management)</span> system is a type of network hardware appliance, virtual appliance or cloud service that protects businesses from security threats in a simplified way by combining and integrating multiple security services and features.\r\nUnified threat management <span style=\"font-weight: bold; \">devices </span>are often packaged as network security appliances that can help protect networks against combined security threats, including malware and attacks that simultaneously target separate parts of the network.\r\nUTM <span style=\"font-weight: bold; \">cloud services</span> and virtual network appliances are becoming increasingly popular for network security, especially for smaller and medium-sized businesses. They both do away with the need for on-premises network security appliances, yet still provide centralized control and ease of use for building network security defense in depth. While UTM systems and <span style=\"font-weight: bold; \">next-generation firewalls (NGFWs)</span> are sometimes comparable, unified threat management device includes added security features that NGFWs don't offer.\r\nOriginally developed to fill the network security gaps left by traditional firewalls, NGFWs usually include application intelligence and intrusion prevention systems, as well as denial-of-service protection. Unified threat management devices offer multiple layers of network security, including next-generation firewalls, intrusion detection/prevention systems, antivirus, virtual private networks (VPN), spam filtering and URL filtering for web content.\r\nUnified threat management appliance has gained traction in the industry due to the emergence of blended threats, which are combinations of different types of malware and attacks that target separate parts of the network simultaneously. By creating a single point of defense and providing a single console, unified security management make dealing with varied threats much easier.\r\nUnified threat management products provide increased protection and visibility, as well as control over network security, reducing complexity. Unified threat management system typically does this via inspection methods that address different types of threats. These methods include:\r\n<ul><li><span style=\"font-weight: bold; \">Flow-based inspection,</span> also known as stream-based inspection, samples data that enters a UTM device, and then uses pattern matching to determine whether there is malicious content in the data flow.</li><li> <span style=\"font-weight: bold; \">Proxy-based inspection</span> acts as a proxy to reconstruct the content entering a UTM device, and then executes a full inspection of the content to search for potential security threats. If the content is clean, the device sends the content to the user. However, if a virus or other security threat is detected, the device removes the questionable content, and then sends the file or webpage to the user.</li></ul>\r\n\r\n","materialsDescription":"<h1 class=\"align-center\"> How UTM is deployed?</h1>\r\nBusinesses can implement UTM as a UTM appliance that connects to a company's network, as a software program running on an existing network server, or as a service that works in a cloud environment.\r\nUTMs are particularly useful in organizations that have many branches or retail outlets that have traditionally used dedicated WAN, but are increasingly using public internet connections to the headquarters/data center. Using a UTM in these cases gives the business more insight and better control over the security of those branch or retail outlets.\r\nBusinesses can choose from one or more methods to deploy UTM to the appropriate platforms, but they may also find it most suitable to select a combination of platforms. Some of the options include installing unified threat management software on the company's servers in a data center; using software-based UTM products on cloud-based servers; using traditional UTM hardware appliances that come with preintegrated hardware and software; or using virtual appliances, which are integrated software suites that can be deployed in virtual environments.\r\n<h1 class=\"align-center\">Benefits of Using a Unified Threat Management Solution</h1>\r\nUTM solutions offer unique benefits to small and medium businesses that are looking to enhance their security programs. Because the capabilities of multiple specialized programs are contained in a single appliance, UTM threat management reduces the complexity of a company’s security system. Similarly, having one program that controls security reduces the amount of training that employees receive when being hired or migrating to a new system and allows for easy management in the future. This can also save money in the long run as opposed to having to buy multiple devices.\r\nSome UTM solutions provide additional benefits for companies in strictly regulated industries. Appliances that use identity-based security to report on user activity while enabling policy creation based on user identity meet the requirements of regulatory compliance such as HIPPA, CIPA, and GLBA that require access controls and auditing that meet control data leakage.\r\nUTM solutions also help to protect networks against combined threats. These threats consist of different types of malware and attacks that target separate parts of the network simultaneously. When using separate appliances for each security wall, preventing these combined attacks can be difficult. This is because each security wall has to be managed individually in order to remain up-to-date with the changing security threats. Because it is a single point of defense, UTM’s make dealing with combined threats easier.\r\n\r\n","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_UTM.jpg","alias":"utm-unified-threat-management"},"44":{"id":44,"title":"IAM - Identity and Access Management","description":"<span style=\"font-weight: bold; \">Identity management</span> (IdM), also known as <span style=\"font-weight: bold; \">identity and access management</span> (IAM or IdAM), is a framework of policies and technologies for ensuring that the proper people in an enterprise have the appropriate access to technology resources. IdM systems fall under the overarching umbrellas of IT security and Data Management.\r\nWith an IAM framework in place, information technology (IT) managers can control user access to critical information within their organizations. Identity and access management software offers role-based access control, which lets system administrators regulate access to systems or networks based on the roles of individual users within the enterprise. In this context, access is the ability of an individual user to perform a specific task, such as view, create or modify a file. Roles are defined according to job competency, authority and responsibility within the enterprise.\r\nSystems used for identity and access management include single sign-on systems, multi-factor authentication and privileged access management (PAM). These technologies also provide the ability to securely store identity and profile data as well as data governance functions to ensure that only data that is necessary and relevant is shared. IAM systems can be deployed on premises, provided by a third-party vendor through a cloud-based subscription model or deployed in a hybrid cloud.\r\n<span style=\"font-weight: bold; \">Basic components of IAM.</span> On a fundamental level, IAM encompasses the following components:\r\n<ul><li>How individuals are identified in a system.</li><li>How roles are identified in a system and how they are assigned to individuals.</li><li>Adding, removing and updating individuals and their roles in a system.</li><li>Assigning levels of access to individuals or groups of individuals.</li><li>Protecting the sensitive data within the system and securing the system itself.</li></ul>\r\nAccess identity management system should consist of all the necessary controls and tools to capture and record user login information, manage the enterprise database of user identities and orchestrate the assignment and removal of access privileges. That means that systems used for IAM should provide a centralized directory service with oversight as well as visibility into all aspects of the company user base.\r\nTechnologies for identity access and management should simplify the user provisioning and account setup process. User access management software should reduce the time it takes to complete these processes with a controlled workflow that decreases errors as well as the potential for abuse while allowing automated account fulfillment. An identity and access management system should also allow administrators to instantly view and change access rights.\r\nIAM systems should be used to provide flexibility to establish groups with specific privileges for specific roles so that access rights based on employee job functions can be uniformly assigned. Identity access management software should also provide request and approval processes for modifying privileges because employees with the same title and job location may need customized, or slightly different, access.\r\n\r\n","materialsDescription":"<h1 class=\"align-center\"><span style=\"font-weight: bold; \">What is the difference between identity and access management?</span></h1>\r\nAfter authentication, there needs to be an access control decision. The decision is based on the information available about the user. The difference between identity management and access management is thus:\r\n<ul><li>Identity Management is about managing the attributes related to the user.</li><li>Access Management is about evaluating the attributes based on policies and making Yes/No decisions.</li></ul>\r\nThere are three types of Access Control Systems: \r\n<ul><li>Discretionary Access Control (DAC)</li><li>Mandatory Access Control (MAC)</li><li>Role-Based Access Control (RBAC)</li></ul>\r\n<h1 class=\"align-center\">What are the main benefits of identity management?</h1>\r\nIdentity access and management are useful in many ways: it ensures regulatory compliance, enables cost savings, and simplifies the lives of your customers by enhancing their experience. These are the main benefits of having an IAM solution:\r\n<ul><li><span style=\"font-weight: bold; \">Easily accessible anywhere</span></li></ul>\r\nNowadays, people need their identities all the time to use services and resources. In that sense, they require access to any platform without limits using their IDs, thus eliminating barriers for customers to enter the platform anytime, anywhere.\r\n<ul><li><span style=\"font-weight: bold; \">It encourages the connection between the different parts</span></li></ul>\r\nThe digital transformation that is taking place among more and more organizations forces the need for people, applications and devices to stay connected to each other. And, as expected, all of these processes bring with them some security threats.\r\nHowever, IAM software is a solution that guarantees correct administration with the best identity providers, such as Salesforce, Twitter and Google. Authentication and security are two of the strengths of Identity and Access Management, as well as being extendable and ready for future advances. \r\n<ul><li><span style=\"font-weight: bold; \">It improves productivity</span></li></ul>\r\nIdentity software automates the entry of new personnel and facilitates access to all components of the system with which the company operates. This allows reducing times in the delivery of access so that they begin to produce immediately. For this reason, business agility is also increased by using the advantages that technology makes available to meet the demands of today’s world. \r\n<ul><li><span style=\"font-weight: bold; \">It optimizes user experience</span></li></ul>\r\nRemembering so many usernames and passwords to access social networks, banks and other services on the Internet becomes a challenge for people. Thanks to user identity management system, people can get an identity that provides access to different systems. Single sign-on (SSO) allows customers and partners to access different internal and external applications with the same access method. That way the user experience will not be affected.\r\n<ul><li><span style=\"font-weight: bold; \">Secure your brand at all levels</span></li></ul>\r\nThere will be no risk of security breach, regardless of whether a connection is made from multiple identity providers. Identity management software and access management software enables strong authentication to keep your business and brand secure. Detailed verification of all identities entering the system is performed, in addition to allowing various licenses to limit access levels. At the same time, it monitors through analysis, fraud detection and alert functions that indicate a possible real risk. In short, enterprise identity management system is a reliable tool that employs technology to support digital transformation. A software that provides agility, security and satisfaction to the company’s customers.

Recently, Data Protection and Recovery Software market are disrupted by innovative technologies such as server virtualization, disk-based backup, and cloud services where emerging players are playing an important role. Tier one players such as IBM, Hewlett Packard Enterprise, EMC Corporation, Symantec Corporation and Microsoft Corporation are also moving towards these technologies through partnerships and acquisitions.\r\nThe major factor driving data protection and recovery software market is the high adoption of cloud-based services and technologies. Many organizations are moving towards the cloud to reduce their operational expenses and to provide real-time access to their employees. However, increased usage of the cloud has increased the risk of data loss and data theft and unauthorized access to confidential information, which increases the demand for data protection and recovery solution suites.","materialsDescription":" \r\n<span style=\"font-weight: bold; \">What is Data recovery?</span>\r\nData recovery is a process of salvaging (retrieving) inaccessible, lost, corrupted, damaged or formatted data from secondary storage, removable media or files, when the data stored in them cannot be accessed in a normal way. The data is most often salvaged from storage media such as internal or external hard disk drives (HDDs), solid-state drives (SSDs), USB flash drives, magnetic tapes, CDs, DVDs, RAID subsystems, and other electronic devices. Recovery may be required due to physical damage to the storage devices or logical damage to the file system that prevents it from being mounted by the host operating system (OS).\r\nThe most common data recovery scenario involves an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive. This can be easily accomplished using a Live CD or DVD by booting directly from a ROM instead of the corrupted drive in question. Many Live CDs or DVDs provide a means to mount the system drive and backup drives or removable media, and to move the files from the system drive to the backup media with a file manager or optical disc authoring software. Such cases can often be mitigated by disk partitioning and consistently storing valuable data files (or copies of them) on a different partition from the replaceable OS system files.\r\nAnother scenario involves a drive-level failure, such as a compromised file system or drive partition, or a hard disk drive failure. In any of these cases, the data is not easily read from the media devices. Depending on the situation, solutions involve repairing the logical file system, partition table or master boot record, or updating the firmware or drive recovery techniques ranging from software-based recovery of corrupted data, hardware- and software-based recovery of damaged service areas (also known as the hard disk drive's "firmware"), to hardware replacement on a physically damaged drive which allows for extraction of data to a new drive. If a drive recovery is necessary, the drive itself has typically failed permanently, and the focus is rather on a one-time recovery, salvaging whatever data can be read.\r\nIn a third scenario, files have been accidentally "deleted" from a storage medium by the users. Typically, the contents of deleted files are not removed immediately from the physical drive; instead, references to them in the directory structure are removed, and thereafter space the deleted data occupy is made available for later data overwriting. In the mind of end users, deleted files cannot be discoverable through a standard file manager, but the deleted data still technically exists on the physical drive. In the meantime, the original file contents remain, often in a number of disconnected fragments, and may be recoverable if not overwritten by other data files.\r\nThe term "data recovery" is also used in the context of forensic applications or espionage, where data which have been encrypted or hidden, rather than damaged, are recovered. Sometimes data present in the computer gets encrypted or hidden due to reasons like virus attack which can only be recovered by some computer forensic experts.\r\n<span style=\"font-weight: bold;\">What is a backup?</span>\r\nA backup, or data backup, or the process of backing up, refers to the copying into an archive file of computer data that is already in secondary storage—so that it may be used to restore the original after a data loss event. The verb form is "back up" (a phrasal verb), whereas the noun and adjective form is "backup".\r\nBackups have two distinct purposes. The primary purpose is to recover data after its loss, be it by data deletion or corruption. Data loss can be a common experience of computer users; a 2008 survey found that 66% of respondents had lost files on their home PC. The secondary purpose of backups is to recover data from an earlier time, according to a user-defined data retention policy, typically configured within a backup application for how long copies of data are required. Though backups represent a simple form of disaster recovery and should be part of any disaster recovery plan, backups by themselves should not be considered a complete disaster recovery plan. One reason for this is that not all backup systems are able to reconstitute a computer system or other complex configuration such as a computer cluster, active directory server, or database server by simply restoring data from a backup.\r\nSince a backup system contains at least one copy of all data considered worth saving, the data storage requirements can be significant. Organizing this storage space and managing the backup process can be a complicated undertaking. A data repository model may be used to provide structure to the storage. Nowadays, there are many different types of data storage devices that are useful for making backups. There are also many different ways in which these devices can be arranged to provide geographic redundancy, data security, and portability.\r\nBefore data are sent to their storage locations, they are selected, extracted, and manipulated. Many different techniques have been developed to optimize the backup procedure. These include optimizations for dealing with open files and live data sources as well as compression, encryption, and de-duplication, among others. Every backup scheme should include dry runs that validate the reliability of the data being backed up. It is important to recognize the limitations and human factors involved in any backup scheme.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/Data_Protection_and_Recovery_Software__1_.png","alias":"data-protection-and-recovery-software"},"51":{"id":51,"title":"PaaS - Platform as a service","description":"<span style=\"font-weight: bold; \">Platform as a Service (PaaS)</span> or <span style=\"font-weight: bold; \">Application Platform as a Service (aPaaS)</span> or <span style=\"font-weight: bold; \">platform-based service</span> is a category of cloud computing services that provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app.\r\n<span style=\"font-weight: bold; \">PaaS can be delivered in three ways:</span>\r\n<span style=\"font-weight: bold;\">As a public cloud service</span> from a provider, where the consumer controls software deployment with minimal configuration options, and the provider provides the networks, servers, storage, operating system (OS), middleware (e.g. Java runtime, .NET runtime, integration, etc.), database and other services to host the consumer's application.\r\n<span style=\"font-weight: bold;\">As a private service</span> (software or appliance) behind a firewall.\r\n<span style=\"font-weight: bold;\">As software</span> deployed on a public infrastructure as a service.\r\n<span style=\"color: rgb(97, 97, 97); \">The original intent of PaaS technology was to simplify the code-writing process for developers, with the infrastructure and operations handled by the PaaS provider.

As a result, public PaaS and IaaS (infrastructure as a service) run together, with PaaS operating on top of a vendor's IaaS infrastructure while leveraging the public cloud. \r\n<ul><li><span style=\"font-weight: bold; \">Private PaaS</span></li></ul>\r\nA private PaaS is usually delivered as an appliance or software within the user's firewall which is frequently maintained in the company's on-premises data center. A private PaaS software can be developed on any type of infrastructure and can work within the company's specific private cloud. Private PaaS allows an organization to better serve developers, improve the use of internal resources and reduce the costly cloud sprawl that many companies face.\r\n<ul><li><span style=\"font-weight: bold; \">Hybrid PaaS </span></li></ul>\r\nCombines public PaaS and private PaaS to provide companies with the flexibility of infinite capacity provided by a public PaaS model and the cost efficiencies of owning an internal infrastructure in private PaaS. Hybrid PaaS utilizes a hybrid cloud.\r\n<ul><li><span style=\"font-weight: bold; \">Communication PaaS </span></li></ul>\r\nCPaaS is a cloud-based platform that allows developers to add real-time communications to their apps without the need for back-end infrastructure and interfaces. Normally, real-time communications occur in apps that are built specifically for these functions. Examples include Skype, FaceTime, WhatsApp and the traditional phone. CPaaS provides a complete development framework for the creation of real-time communications features without the necessity of a developer building their own framework.\r\n<ul><li><span style=\"font-weight: bold; \">Mobile PaaS</span> </li></ul>\r\nMPaaS is the use of a paid integrated development environment for the configuration of mobile apps. In an mPaaS, coding skills are not required. MPaaS is delivered through a web browser and typically supports public cloud, private cloud and on-premises storage. The service is usually leased with pricing per month, varying according to the number of included devices and supported features.\r\n<ul><li><span style=\"font-weight: bold; \">Open PaaS</span></li></ul>\r\nIt is a free, open source, business-oriented collaboration platform that is attractive on all devices and provides useful web apps, including calendar, contacts and mail applications. OpenPaaS was designed to allow users to quickly deploy new applications with the goal of developing a PaaS technology that is committed to enterprise collaborative applications, specifically those deployed on hybrid clouds.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/PaaS_-_Platform_as_a_service.png","alias":"paas-platform-as-a-service"},"227":{"id":227,"title":"Advanced Analytics Software","description":" <span style=\"font-weight: bold;\">Advanced analytics</span> is a part of data science that uses high-level methods and tools to focus on projecting future trends, events, and behaviors.

This type of design is smart enough, as it parallels a two-level programming model that separates the data layer from the user interface and allows you to concentrate the software market directly on improving its products. This model opens doors for third parties who create their own applications for interacting with various databases.\r\nDatabase development tools can be used to create varieties of the following programs:\r\n<ul><li>client programs;</li><li>database servers and their individual components;</li><li>custom applications.</li></ul>\r\nThe programs of the first and second types are rather small since they are intended mainly for system programmers.

Even if the cost of disk memory is reduced by an average of 30% per year, the demand for it increases by 100% during the same time, so the total amount of data storage costs will grow by 40%. The fact that memory is used inefficiently has a sensitive effect on meager IT budgets. So is it possible to control disk assets in order to get the most return on investment?\r\nPositive answers to these questions are provided by the storage resource management system. For example, what should an administrator do if he is responsible for accessing data at the bank if customer service is suspended at the very height of the trading day due to slow application performance? One of the probable reasons is that the disk space required by the application is almost exhausted. How quickly does the network administrator identify the true cause of the collapse? Could he have foreseen and prevented her? If it was possible to set a threshold for the acceptable size of free disk space in the relevant rules, he would have received a notification in advance that the file system was about to begin to run out of disk space, and would be able to take appropriate measures in time.\r\nStorage networks today require constant high availability - a good reason to use monitoring systems and analysis tools not only when a problem has already arisen. In addition, a comprehensive overview of the storage network is usually required.\r\nIn large data centers, managing drives is significantly more expensive than acquiring them. When using, in particular, SAN, thanks to centralized administration and management through switches and directors, it was already possible to significantly save on management. With scalable storage capacity in SANs, high availability and performance make it easy to provide and manage bulk storage in large data centers. However, increasing capacity, increasing data transfer rates, heterogeneous equipment from different manufacturers and virtualization technologies make monitoring the structure of storage networks and analyzing internal processes more and more difficult. Obviously, for the network administrator, they create new difficulties, which in professional jargon are called "network blindness." By this we mean the inability to diagnose, analyze and prevent failures, and, in addition, complex protocols and structures reduce network performance.\r\nOvercoming “blindness” is of great practical importance. Many companies risk significant damage already in the first four hours after the failure, and the loss of enterprises specializing, for example, in electronic commerce and financial institutions, reaches hundreds of thousands or even several million dollars per hour. These figures once again convince us that there is a need to respond very quickly to failures and performance problems.","materialsDescription":"<span style=\"font-weight: bold;\">Storage device management utilities</span>\r\n<ul><li>Backup software makes copies of all information stored on a disk and restores either the entire disk (aka Disk cloning) in an event of disk failure or selected files that are accidentally deleted or corrupted.

Companies require the production of high-quality software at unprecedented speeds. Software application requirements continue to grow more complex often with shorter and more frequent release cycles. Distributed development teams present challenges related to effective teaming, parallel development and diverse platforms - these factors and more intensify the pressures of developing quality software. Developing quality software in a repeatable and predictable fashion requires managing and tracking development artifacts and the activities of the development team. Successful development teams utilize software configuration management and software change management tools to help manage the software development lifecycle.\r\nSoftware configuration management provides version control and parallels development support to manage and control software assets. Software change management provides defect tracking and automation of software processes across the development lifecycle.\r\nSolutions that combine software configuration management and software change management in a single, tightly integrated solution are referred to as software change and configuration management (SCCM) solutions. SCCM solutions utilize activities to easily manage changes made to development artifacts. Unlike standalone SCM tools, SCCM solutions usually include substantial workflow capabilities which automate and effectively govern the software development processes for repeatable and predictable software development.\r\nEssentially, SCCM answers the ‘who’, ‘what’, ‘when’, and ‘why’ of software development. Who made the changes? What changes were made to the software? When were the changes made? Why were the changes made? Development teams and project leaders should be able to obtain answers to these questions to manage a project's activities, determine project status and track the actual product evolution.\r\nA fully comprehensive software change and configuration management (SCCM) solution empowers companies by accelerating software and systems delivery, making global teams more efficient, and governing the end-to-end software development processes.

What's changed is that the <span style=\"font-weight: bold; \">software has become portable</span>.\r\nBut nothing in the storage world elicits more divergent opinions than the term "software-defined storage products". With no universally accepted definition, SDS is vendor-specific. Software defined storage leaders shape the SDS definition to match their storage offerings. The result is that every storage vendor appears to offer SDS.\r\nStorage system software historically was tied to the hardware it managed. When the hardware ran out of capacity or performance, it had to be replaced and the software licensing was repurchased along with the hardware.<br />What made matters significantly worse was that storage system architectures created isolated silos. Unique infrastructures made everything from storage provisioning, data protection, disaster recovery, tech refresh, data migration, power and cooling more and more untenable. Compound that with the ongoing trend of rapid data growth and the need to store ever-increasing amounts of data, and the available architectures made storage systems management too complicated, difficult, expensive and ultimately unmaintainable.\r\n<h1 class=\"align-center\"><span style=\"font-weight: normal;\">What are SDS categories pros and cons?</span></h1>\r\n With no working standard SDS definition, a variety of technologies have emerged in the software-defined storage market.

VSAN works with both hard disk drives (HDDs) and solid-state drives (SSDs), including DIMM-based flash drives, PCIe, SAS, SATA and even NVMe. VMware vSAN supports both HDDs and SSDs in a hybrid mode or all SSDs in all-flash mode.<span style=\"font-weight: bold; \"></span>\r\n<span style=\"font-weight: bold; \">Scalability and performance</span>. VSAN is highly scalable while delivering high levels of performance. It scales out through vSphere clustering and can support up to 64 vSphere hosts per cluster. Each vSphere host supports approximately 140 TB raw storage capacity and well north of 8 PB of raw storage capacity per cluster. On the performance side, each vSAN host can supply 100,000 or more IOPS, yielding millions of IOPS per cluster.\r\n<p class=\"align-center\"><span style=\"font-weight: bold;\">Hypervisor-based SDS cons:</span></p>\r\n<span style=\"font-weight: bold; \">Scalability and performance issues.</span> If a VM requires more IOPS than one physical vSphere host can provide, it can get them from other nodes in the cluster, but with a considerable latency penalty. Inter-cluster storage performance is another issue. Most vSAN clusters use 10 Gbps to 40 Gbps Ethernet and TCP/IP to interconnect the hosts. This architecture essentially replaces a deterministic system bus with a non-deterministic TCP/IP network so latencies between hosts become highly variable. Unless the cluster uses more sophisticated and faster interconnections, its storage performance from one clustered host to another will be highly variable and inconsistent.<span style=\"font-weight: bold; \"></span>\r\n<span style=\"font-weight: bold; \">Some things are not so simple. </span>Converting from a siloed storage environment to a pure vSAN requires converting non-VM images to VMs first.

Scaling storage capacity just requires adding drives (HDDs or SSDs) up to a node's maximum or adding additional nodes. Each HCI product has its own scalability and performance limitations; however, most scale well into the PBs and add performance linearly with each server node added to the cluster.<span style=\"font-weight: bold; \"></span>\r\n<span style=\"font-weight: bold; \">Simplicity. </span>Plug it in, turn it on, configure and you're done. Few systems are simpler.

If a VM requires more IOPS than a given host can provide, it can get IOPS from other nodes, but with a considerable latency penalty. Inter-cluster storage performance is another issue. Most HCI clusters use 10 Gbps to 40 Gbps Ethernet and TCP/IP to interconnect the hosts so latencies between hosts can be highly variable.<span style=\"font-weight: bold; \"></span>\r\n<span style=\"font-weight: bold; \">Some things are not so simple.</span> Converting from a siloed storage environment to an HCI cluster requires first converting both non-VM images and VMs to the HCI VMs or Docker containers, a time-consuming process.\r\n<p class=\"align-center\"><span style=\"font-weight: bold;\">Storage virtualization SDS pros:</span></p>\r\n<span style=\"font-weight: bold; \"></span><span style=\"font-weight: bold;\">Flexibility.</span> It works with most x86 physical hosts or VMs as long as the hardware or hypervisor is certified and supported by the vendor. It converts all storage that sits behind it into the virtual storage pool, enabling repurposing of older storage. The scale-out versions permit physical or VM access to any node. Multi-copy mirroring isn't necessary to protect against a single controller failure, although it's available. Storage virtualization SDS can be provided as software or bundled with server hardware similar to HCI.<span style=\"font-weight: bold; \"></span>\r\n<span style=\"font-weight: bold; \">Total cost of ownership (TCO)</span>. The biggest cost savings in storage virtualization SDS comes from commodity hardware and server-based drives. Another cost saving comes from inline data reduction technologies.

Storage virtualization SDS capacity is constrained by x86 server limitations. Each server can handle only so much capacity before performance declines below acceptable levels. Storage virtualization SDS scale-out is constrained by clustering because the number of storage controller nodes supported is limited. Performance may also be constrained by the same limitations. \r\n<p class=\"align-center\"><span style=\"font-weight: bold; \">Scale-out object and/or file SDS pros:<br /></span></p>\r\n<span style=\"font-weight: bold; \">Scalability and performance. </span>Scaling is multi-dimensional: each node can be scaled individually and generally the cluster itself can add nodes for capacity or performance.

Implementing it as software requires DIY systems integration. Both types leverage commodity hardware, have exceptional scalability and -- in the case of scale-out object storage -- unmatched data resilience and longevity via erasure coding.\r\n<p class=\"align-center\"><span style=\"font-weight: bold;\">Scale-out object and/or file SDS cons:</span></p>\r\n<span style=\"font-weight: bold;\">Flexibility issues. </span>Whether delivered as software or bundled with hardware, the hardware must be certified and supported by the vendors.\r\n<span style=\"font-weight: bold; \">Scalability and performance issues.</span> Scale-out file SDS generally doesn't scale as high as scale-out object storage, but object will have somewhat higher latencies.

The most common heights are between 8U to 50U, but customization is also a viable option if you’re working with nonstandard sizes.\r\n<span style=\"font-weight: bold;\">Are there any specific ventilation requirements with server racks?</span>\r\nOver 65% of IT equipment failures are directly attributed to inadequate, poorly maintained, or failed air conditioning in the server room. So yes, proper ventilation is a critical part of maintaining any data center. Some cabinet manufacturers construct side panel ventilation instead of front and back ventilation, but experts say it’s inadequate for rack mount servers. This can be especially dangerous if more than one cabinet is being set up at once. The importance of proper ventilation should not be taken lightly, and you should always opt for front to back ventilation except in network applications where the IT equipment exhausts out the side.\r\n<span style=\"font-weight: bold;\">What is meant by ‘server rack depth’?</span>\r\nServer rack depth is a critical aspect of the ventilation process. Connectworld.net says, “Server cabinet depth is important not only because it has to allow room for the depth of the particular equipment to be rack-mounted (deep servers vs. routers or switches), but also it has to allow sufficient room for cables, PDU’s as well as airflow.<br /><br />","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Rack_Server.png","alias":"rack-server"},"453":{"id":453,"title":"Desktop PC","description":" A desktop computer is a personal computer designed for regular use at a single location on or near a desk or table due to its size and power requirements.

The next major portables were Osborne's 24 pound CP/M-based Osborne 1 (1981) and Compaq's 28 pound 100% IBM PC compatible Compaq Portable (1983). These "luggable" computers lacked the next technological development, not requiring an external power source; that feature was introduced by the laptop. Laptops were followed by lighter models, so that in the 2000's mobile devices and by 2007 smartphones made the term almost meaningless. The 2010's introduced wearable computers such as smartwatches.\r\nPortable computers, by their nature, are generally microcomputers. Larger portable computers were commonly known as 'Lunchbox' or 'Luggable' computers. They are also called 'Portable Workstations' or 'Portable PCs'. In Japan they were often called 'Bentocom'.

A portable computer in this usage, versus a laptop or other mobile computing device, have a standard motherboard or backplane providing plug-in slots for add-in cards. This allows mission specific cards such as test, A/D, or communication protocol (IEEE-488, 1553) to be installed. Portable computers also provide for more disk storage by using standard disk drives and provide for multiple drives.\r\nPortable computers have been increasing in popularity over the past decade, as they do not restrict the user's mobility as a desktop computer does, and do not restrict the computer power and storage available as a laptop computer does.

A monitor usually comprises the display device, circuitry, casing, and power supply. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) with LED backlighting having replaced cold-cathode fluorescent lamp (CCFL) backlighting. Older monitors used a cathode ray tube (CRT). Monitors are connected to the computer via VGA, Digital Visual Interface (DVI), HDMI, DisplayPort, Thunderbolt, low-voltage differential signaling (LVDS) or other proprietary connectors and signals.\r\nOriginally, computer monitors were used for data processing while television sets were used for entertainment. From the 1980s onwards, computers (and their monitors) have been used for both data processing and entertainment, while televisions have implemented some computer functionality. The common aspect ratio of televisions, and computer monitors, has changed from 4:3 to 16:10, to 16:9.\r\nModern computer monitors are easily interchangeable with conventional television sets. However, as computer monitors do not necessarily include integrated speakers, it may not be possible to use a computer monitor without external components.","materialsDescription":" <span style=\"font-weight: bold; \">What is an LCD monitor (TFT)?</span>\r\nLiquid crystal monitor (also Liquid crystal display, LCD monitor, flat indicator) - a flat monitor based on liquid crystals.\r\nLCD TFT is one of the names of the liquid crystal display, which uses an active matrix controlled by thin-film transistors. The TFT amplifier for each subpixel is used to increase the speed, contrast and clarity of the display image.\r\n<span style=\"font-weight: bold; \">How does an LCD monitor work?</span>\r\nEach pixel of the LCD display consists of a layer of molecules between two transparent electrodes, and two polarizing filters, the polarization planes of which (as a rule) are perpendicular. In the absence of liquid crystals, the light transmitted by the first filter is almost completely blocked by the second.\r\nThe surface of the electrodes in contact with liquid crystals is specially processed for the initial orientation of the molecules in one direction. In the TN matrix, these directions are mutually perpendicular, therefore, the molecules line up in a helical structure in the absence of voltage. This structure refracts the light in such a way that, before the second filter, the plane of its polarization rotates, and light passes through it already without loss. Except for the absorption by the first filter of half of the unpolarized light, the cell can be considered transparent. If voltage is applied to the electrodes, the molecules tend to line up in the direction of the field, which distorts the helical structure. In this case, the elastic forces counteract this, and when the voltage is turned off, the molecules return to their original position. With a sufficient field value, almost all molecules become parallel, which leads to the opacity of the structure. By varying the voltage, you can control the degree of transparency. If a constant voltage is applied for a long time, the liquid crystal structure may degrade due to ion migration. To solve this problem, an alternating current is applied, or a change in the field polarity at each addressing of the cell (the opacity of the structure does not depend on the field polarity). In the entire matrix, each of the cells can be controlled individually, but with an increase in their number this becomes difficult to accomplish, as the number of required electrodes increases. Therefore, row and column addressing is used almost everywhere. The light passing through the cells can be natural - reflected from the substrate (in LCD displays without backlight). But more often an artificial light source is used, in addition to independence from external lighting, this also stabilizes the properties of the resulting image. Thus, a full-fledged LCD monitor consists of electronics that process the input video signal, LCD matrix, backlight module, power supply and housing. It is the combination of these components that determines the properties of the monitor as a whole, although some characteristics are more important than others.\r\n<span style=\"font-weight: bold;\">What are the most important features of LCD monitors?</span>\r\n<ul><li><span style=\"font-style: italic;\">Resolution:</span> The horizontal and vertical sizes, expressed in pixels.

These technologies differ in the geometry of the surfaces, the polymer, the control plate, and the front electrode. Of great importance are the purity and type of polymer with the properties of liquid crystals, used in specific developments.\r\nThe response time of LCD monitors designed using SXRD technology (English Silicon X-tal Reflective Display - silicon reflective liquid crystal matrix) is reduced to 5 ms. Sony, Sharp, and Philips have jointly developed PALC technology (Plasma Addressed Liquid Crystal - Plasma Control of Liquid Crystals), which combines the advantages of LCD (brightness and color richness, contrast) and plasma panels (large viewing angles, H, and vertical, V, high refresh rate). These displays use gas-discharge plasma cells as a brightness controller, and an LCD matrix is used for color filtering. PALC technology allows you to address each pixel of the display individually, which means unsurpassed controllability and image quality.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Monitor.png","alias":"monitor"},"473":{"id":473,"title":"Projector","description":" A video projector is an image projector that receives a video signal and projects the corresponding image on a projection screen using a lens system. All video projectors use a very bright ultra high pressure mercury lamp, LED or solid state blue, RB, RGB or remote fiber optic RGB lasers to provide the illumination required to project the image, and most modern ones can correct any curves, blurriness, and other inconsistencies through manual settings. If a blue laser is used, a phosphor wheel is used to turn blue light into white light, which is also the case with white LEDs. (White LEDs do not use lasers.) A wheel is used in order to prolong the lifespan of the phosphor, as it is degraded by the heat generated by the laser diode. Remote fiber optic RGB laser racks can be placed far away from the projector, and several racks can be housed in a single, central room. Each projector can use up to 2 racks, and several monochrome lasers are mounted on each rack, the light of which is mixed and transmitted to the projector booth using optical fibers. Projectors using RB lasers use a blue laser with a phosphor wheel in conjuntion with a conventional solid state red laser.\r\nVideo projectors are used for many applications such as conference room presentations, classroom training, home cinema and concerts. In schools and other educational settings, they are sometimes connected to an interactive whiteboard. In the late 20th century they became commonplace in home cinema. Although large LCD television screens became quite popular, video projectors are still common among many home theater enthusiasts.\r\nA video projector, also known as a digital projector, may project onto a traditional reflective projection screen, or it may be built into a cabinet with a translucent rear-projection screen to form a single unified display device.\r\nCommon display resolutions include SVGA (800×600 pixels), XGA (1024×768 pixels), SXGA+ (1400x1050 pixels), 720p (1280×720 pixels), and 1080p (1920×1080 pixels), 4K UHD (3840x2160), as well as 16:10 aspect ratio resolutions including WXGA+ (1280x800 pixels) and WUXGA (1920x1200 pixels).\r\nThe cost of a projector is typically driven by its base technology, features, resolution, and light output. A projector with a higher light output (measured in lumens, “lm”) is required for a larger screen or for a room with a larger amount of ambient light. For example, a light output of approximately 1500 to 2500 ANSI lumens is suitable for small screens viewed in rooms with low ambient light; approximately 2500 to 4000 lm is suitable for medium-sized screens with some ambient light; over 4000 lm is needed for very large screens or for use in rooms with no lighting control such as conference rooms. High brightness large-venue models are increasingly common in Boardrooms, Auditoriums and other high profile spaces, and models up to 30,000 lm are used in large staging applications such as concerts, keynote addresses and displays projected on buildings.\r\nA few camcorders have a built-in projector suitable to make a small projection; a few more powerful "pico projectors" are pocket-sized, and many projectors are portable. ","materialsDescription":" <span style=\"font-weight: bold;\">What's the Difference Between DLP LCD, and LED Projectors?</span>\r\nMainstream projectors use one of several technologies to project an image on a wall or screen. Liquid Crystal Display (LCD) projectors, which have been around for years, use three separate glass panels that separate the color spectrum into red, green, and blue to create an image. The newer digital light processing (DLP) processing integrates Texas Instruments’ DLP chip, which is a reflective surface with thousands of tiny, spinning mirrors, takes the reflected light and puts it through a color wheel to create an image. The smallest projectors, called Pico projectors, use solid-state technology, such as Light Emitting Diodes (LEDs), which are desirable in portable projectors for low power consumption.\r\n<span style=\"font-weight: bold;\">How Much Brightness Do I Need?</span>\r\nBrightness (how much light the projector can produce) is measured in ANSI lumens. The brightness of the room where you’ll be projecting will dictate the lumens you will need. That is, brighter rooms need a projector with higher lumens. For dark rooms, 1000 to 1200 lumens is probably adequate, although professional presenters tend to want 1800 lumens or more. In addition, if you are projecting large images, you’ll want a projector with a higher brightness rating. When choosing your projector, consider your application, the size of your group, the size of your room and the amount of light in the room.\r\n<span style=\"font-weight: bold;\">What Resolution Do I Need?</span>\r\nResolution is the term used to describe the number of pixels, used to display an image. Higher resolutions--more pixels are used to create the image--allow you to display more information on your screen and create a crisper, cleaner image. Today, you’ll see a number of possible resolutions: SVGA (800x600 pixels), XGA (1024x768 pixels) and SXGA (1280x1024 pixels). For standard presentations, 800x600 pixels may be sufficient, but for other uses (such as larger images or advanced presentations) you’ll want a higher resolution, such as 1024x768. The highest resolutions may be needed for presenting detailed AutoCAD drawings or videos.\r\n<span style=\"font-weight: bold;\">What Contrast Ratio Do I Need?</span>\r\nContrast ratio measures how well a projector can reproduce black and white. Although the contrast ratio is not terribly important to those using projectors for still presentations, this measure is more important if you will be projecting video. Currently, there is no industry-standard method for measuring contrast ratio, so this stat may vary between manufacturers. Basically, a higher contrast ratio indicates a greater ability for the projector to show subtle color details and tolerate extraneous room light.\r\n<span style=\"font-weight: bold;\">What Input/Output Options Do I Want?</span>\r\nToday’s projectors offer an array of input and output connectors. A projector with both HDMI and VGA ports lets you connect to many different video sources, including set-top boxes; DVD, HD DVD, and Blu-ray Disc players; camcorders; PCs; video game consoles; and AV receivers. HDMI (High-Definition Multimedia Interface) supports any uncompressed TV or PC video format on a single cable, including standard, enhanced, and high-definition video; up to eight channels of compressed or uncompressed digital audio; a Consumer Electronics Control (CEC) connection; and an Ethernet data connection.\r\n<span style=\"font-weight: bold;\">How Much Should I Worry About Projector Weight?</span>\r\nCommon sense should reign when decided what size projector to buy. Consider whether you will be traveling with your projector and choose accordingly. A hard-sized case with wheels will also ease transport.\r\n<span style=\"font-weight: bold;\">What Is a Normal Warranty?</span>\r\nDepending on the projector brand, warranties do vary. Generally, the projector is covered for a year, with the lamp having a shorter coverage (30 days to six months).\r\n<span style=\"font-weight: bold;\">How Long Will My Lamp Last?</span>\r\nBoth DLP and LCD projectors integrate lamps (light bulbs optimized for use in a projector). Lamp life is measured in hours (example, 2000 or 4000), which for most users will translate to years of use. Over time, the brightness of the lamp may deteriorate. LED projectors, meanwhile, do not use a lamp. The result is that these projectors generate less heat and demand virtually no maintenance. Meanwhile, since LEDs incorporate no lead or mercury, these projectors provide a compelling solution for those seeking a green projector.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Projector.jpg","alias":"projector"},"499":{"id":499,"title":"SDN Software-Defined Network","description":" <span style=\"font-weight: bold; \">Software-defined networking (SDN)</span> technology is an approach to network management that enables dynamic, programmatically efficient network configuration in order to improve network performance and monitoring, making it more like cloud computing than traditional network management.\r\nSDN encompasses several types of technologies, including functional separation, network virtualization and automation through programmability. SDN solution is meant to address the fact that the static architecture of traditional networks is decentralized and complex while current networks require more flexibility and easy troubleshooting. \r\nSDN technology attempts to centralize network intelligence in one network component by disassociating the forwarding process of network packets (<span style=\"font-weight: bold; \">data plane</span>) from the routing process (<span style=\"font-weight: bold; \">control plane</span>). The control plane consists of one or more controllers which are considered as the brain of SDN network where the whole intelligence is incorporated. Originally, software defined technology focused solely on separation of the network control plane from the data plane. While the control plane makes decisions about how packets should flow through the network, the data plane actually moves packets from place to place. \r\nIn a classic SDN scenario, a packet arrives at a network switch, and rules built into the switch's proprietary firmware tell the switch where to forward the packet. These packet-handling rules are sent to the switch from the centralized controller. The switch - also known as a <span style=\"font-weight: bold; \">data plane device</span> - queries the controller for guidance as needed, and it provides the controller with information about traffic it handles. The switch sends every packet going to the same destination along the same path and treats all the packets the exact same way.\r\nSoftware defined networking solutions use an operation mode that is sometimes called adaptive or dynamic, in which a switch issues a route request to a controller for a packet that does not have a specific route. This process is separate from adaptive routing, which issues route requests through routers and algorithms based on the network topology, not through a controller.\r\nThe <span style=\"font-weight: bold;\">virtualization</span> aspect of SDN comes into play through a virtual overlay, which is a logically separate network on top of the physical network. Users can implement end-to-end overlays to abstract the underlying network and segment network traffic. This microsegmentation is especially useful for service providers and operators with multi-tenant cloud environments and cloud services, as they can provision a separate virtual network with specific policies for each tenant.","materialsDescription":"<h1 class=\"align-center\">Benefits of Software Defined Networking</h1>\r\nWith SDN software, an <span style=\"font-weight: bold; \">administrator can change any network switch's rules when necessary</span> - prioritizing, deprioritizing or even blocking specific types of packets with a granular level of control and security. This is especially helpful in a cloud computing multi-tenant architecture, because it enables the administrator to manage traffic loads in a flexible and more efficient manner. Essentially, this enables the administrator to use less expensive commodity switches and have more control over network traffic flow than ever before.\r\nOther benefits of SDN are <span style=\"font-weight: bold; \">network management</span> and <span style=\"font-weight: bold; \">end-to-end visibility.</span>A network administrator need only deal with one centralized controller to distribute policies to the connected switches, instead of configuring multiple individual devices.

SANs are primarily used to enhance accessibility of storage devices, such as disk arrays and tape libraries, to servers so that the devices appear to the operating system as locally-attached devices. A SAN typically is a dedicated network of storage devices not accessible through the local area network (LAN) by other devices, thereby preventing interference of LAN traffic in data transfer.\r\nThe cost and complexity of SANs dropped in the early 2000s to levels allowing wider adoption across both enterprise and small to medium-sized business environments.\r\nA SAN does not provide file abstraction, only block-level operations. However, file systems built on top of SANs do provide file-level access, and are known as shared-disk file systems.\r\nStorage area networks (SANs) are sometimes referred to as network behind the servers and historically developed out of the centralised data storage model, but with its own data network. A SAN is, at its simplest, a dedicated network for data storage. In addition to storing data, SANs allow for the automatic backup of data, and the monitoring of the storage as well as the backup process. A SAN is a combination of hardware and software. It grew out of data-centric mainframe architectures, where clients in a network can connect to several servers that store different types of data. To scale storage capacities as the volumes of data grew, direct-attached storage (DAS) was developed, where disk arrays or just a bunch of disks (JBODs) were attached to servers. In this architecture storage devices can be added to increase storage capacity. However, the server through which the storage devices are accessed is a single point of failure, and a large part of the LAN network bandwidth is used for accessing, storing and backing up data. To solve the single point of failure issue, a direct-attached shared storage architecture was implemented, where several servers could access the same storage device.\r\nDAS was the first network storage system and is still widely implemented where data storage requirements are not very high. Out of it developed the network-attached storage (NAS) architecture, where one or more dedicated file server or storage devices are made available in a LAN. Therefore, the transfer of data, particularly for backup, still takes place over the existing LAN. If more than a terabyte of data was stored at any one time, LAN bandwidth became a bottleneck. Therefore, SANs were developed, where a dedicated storage network was attached to the LAN, and terabytes of data are transferred over a dedicated high speed and bandwidth network. Within the storage network, storage devices are interconnected. Transfer of data between storage devices, such as for backup, happens behind the servers and is meant to be transparent. While in a NAS architecture data is transferred using the TCP and IP protocols over Ethernet, distinct protocols were developed for SANs, such as Fibre Channel, iSCSI, Infiniband. Therefore, SANs often have their own network and storage devices, which have to be bought, installed, and configured. This makes SANs inherently more expensive than NAS architectures.","materialsDescription":"<span style=\"font-weight: bold; \">What is storage virtualization?</span>\r\nA storage area network (SAN) is a dedicated high-speed network or subnetwork that interconnects and presents shared pools of storage devices to multiple servers.\r\nA SAN moves storage resources off the common user network and reorganizes them into an independent, high-performance network. This enables each server to access shared storage as if it were a drive directly attached to the server. When a host wants to access a storage device on the SAN, it sends out a block-based access request for the storage device.\r\nA storage area network is typically assembled using three principle components: cabling, host bus adapters (HBAs), and switches attached to storage arrays and servers. Each switch and storage system on the SAN must be interconnected, and the physical interconnections must support bandwidth levels that can adequately handle peak data activities. IT administrators manage storage area networks centrally.\r\nStorage arrays were initially all hard disk drive systems, but are increasingly populated with flash solid-state drives (SSDs).\r\n<span style=\"font-weight: bold; \">What storage area networks are used for?</span>\r\nFibre Channel (FC) SANs have the reputation of being expensive, complex and difficult to manage. Ethernet-based iSCSI has reduced these challenges by encapsulating SCSI commands into IP packets that don't require an FC connection.\r\nThe emergence of iSCSI means that instead of learning, building and managing two networks -- an Ethernet local area network (LAN) for user communication and an FC SAN for storage -- an organization can use its existing knowledge and infrastructure for both LANs and SANs. This is an especially useful approach in small and midsize businesses that may not have the funds or expertise to support a Fibre Channel SAN.\r\nOrganizations use SANs for distributed applications that need fast local network performance. SANs improve the availability of applications through multiple data paths. They can also improve application performance because they enable IT administrators to offload storage functions and segregate networks.\r\nAdditionally, SANs help increase the effectiveness and use of storage because they enable administrators to consolidate resources and deliver tiered storage. SANs also improve data protection and security. Finally, SANs can span multiple sites, which helps companies with their business continuity strategies.\r\n<span style=\"font-weight: bold;\">Types of network protocols</span>\r\nMost storage networks use the SCSI protocol for communication between servers and disk drive devices.[citation needed] A mapping layer to other protocols is used to form a network:\r\n<ul><li>ATA over Ethernet (AoE), mapping of ATA over Ethernet</li><li>Fibre Channel Protocol (FCP), the most prominent one, is a mapping of SCSI over Fibre Channel</li><li>Fibre Channel over Ethernet (FCoE)</li><li>ESCON over Fibre Channel (FICON), used by mainframe computers</li><li>HyperSCSI, mapping of SCSI over Ethernet</li><li>iFCP or SANoIP mapping of FCP over IP</li><li>iSCSI, mapping of SCSI over TCP/IP</li><li>iSCSI Extensions for RDMA (iSER), mapping of iSCSI over InfiniBand</li><li>Network block device, mapping device node requests on UNIX-like systems over stream sockets like TCP/IP</li><li>SCSI RDMA Protocol (SRP), another SCSI implementation for RDMA transports</li></ul>\r\nStorage networks may also be built using SAS and SATA technologies.

Storage systems for mission-critical applications are focused on the needs of companies of various sizes - from remote branches to large enterprises with significant amounts of information.\r\nAlso many factors affect the selection of a data center location, but utility infrastructure, uptime, talent, and speed are always the focal points.\r\nFew people are unaware of the large electric loads (usage) of data centers. Naturally, due to the amount of power they need, data centers are very price-sensitive to a location’s cost of electricity. The cost is more than centers per kWh, though. Data centers have unique ramp-up needs and reserved capacity demands. The utility’s ability to accommodate these requirements can have a significant impact on cost. Likewise, the mission-critical aspect of the data center, requiring it to be online at all times, drives rigorous power redundancy and reliability requirements.

Hyper-converged infrastructure allows for tighter integration of a larger number of components using software tools.\r\nIn both convergent and hyper-convergent infrastructure, all elements are compatible with each other. Thanks to this, you will be able to purchase the necessary storage devices and network devices for your company at a time, and they, as you know, are of great importance in the virtual desktops infrastructure. This allows you to simplify the process of deploying such an infrastructure - something that has been waiting for and what will be rejoiced by many companies that need to virtualize their desktop systems.\r\nDespite its value and innovation, there are several questions to these technologies regarding their intended use and differences. Let's try to figure out what functionality offers converged and hyper-convergent infrastructures and how they differ.","materialsDescription":" <span style=\"font-weight: bold;\">What is converged infrastructure?</span>\r\nConvergent infrastructure combines computing devices, storage, network devices and server virtualization tools in one chassis so that they can be managed from one place. Management capabilities may include the management of virtual desktop infrastructure, depending on the selected configuration and manufacturer.\r\nThe hardware included in the bundled converged infrastructure is pre-configured to support any targets: virtual desktop infrastructures, databases, special applications, and so on. But in fact, you do not have enough freedom to change the selected configuration.\r\nRegardless of the method chosen for extending the virtual desktop infrastructure environment, you should understand that subsequent vertical scaling will be costly and time-consuming. Adding individual components is becoming complex and depriving you of the many benefits of a converged infrastructure. Adding workstations and expanding storage capacity in a corporate infrastructure can be just as expensive, which suggests the need for proper planning for any virtual desktop infrastructure deployment.\r\nOn the other hand, all components of a converged infrastructure can work for a long time. For example, a complete server of such infrastructure works well even without the rest of the infrastructure components.\r\n<span style=\"font-weight: bold;\">What is a hyper-convergent infrastructure?</span>\r\nThe hyper-converged infrastructure was built on the basis of converged infrastructure and the concept of a software-defined data center. It combines all the components of the usual data center in one system. All four key components of the converged infrastructure are in place, but sometimes it also includes additional components, such as backup software, snapshot capabilities, data deduplication functionality, intermediate compression, global network optimization (WAN), and much more. Convergent infrastructure relies primarily on hardware, and software-defined data center often adapts to any hardware. In the hyper-convergent infrastructure, these two possibilities are combined.\r\nHyper-converged infrastructure is supported by one supplier. It can be managed as a single system with a single set of tools. To expand the infrastructure, you just need to install blocks of necessary devices and resources (for example, storage) into the main system block. And this is done literally on the fly.\r\nSince the hyper-convergent infrastructure is software-defined (that is, the operation of the infrastructure is logically separated from the physical equipment), the mutual integration of components is denser than in a conventional converged infrastructure, and the components themselves must be nearby to work correctly. This makes it possible to use a hyper-convergent infrastructure to support even more workloads than in the case of conventional converged infrastructure. This is explained by the fact that it has the possibility of changing the principle of definition and adjustment at the program level. In addition, you can make it work with specialized applications and workloads, which pre-configured converged infrastructures do not allow.\r\nHyper-converged infrastructure is especially valuable for working with a virtual desktop infrastructure because it allows you to scale up quickly without additional costs. Often, in the case of the classic virtual desktops infrastructure, things are completely different - companies need to buy more resources before scaling or wait for virtual desktops to use the allocated space and network resources, and then, in fact, add new infrastructure.\r\nBoth scenarios require significant time and money. But, in the case of hyperconvergent infrastructure, if you need to expand the storage, you can simply install the required devices in the existing stack. Scaling can be done quickly — for the time required to deliver the equipment. In this case, you do not have to go through the full procedure of re-evaluation and reconfiguration of the corporate infrastructure.\r\nIn addition, when moving from physical PCs to virtual workstations, you will need devices to perform all the computational tasks that laptops and PCs typically perform. Hyper-converged infrastructure will greatly help with this, as it often comes bundled with a large amount of flash memory, which has a positive effect on the performance of virtual desktops. This increases the speed of I / O operations, smoothes work under high loads, and allows you to perform scanning for viruses and other types of monitoring in the background (without distracting users).\r\nThe flexibility of the hyper-converged infrastructure makes it more scalable and cost-effective compared to the convergent infrastructure since it has the ability to add computing and storage devices as needed. The cost of the initial investment for both infrastructures is high, but in the long term, the value of the investment should pay off.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Converged_and_Hyper_Converged_System.png","alias":"converged-and-hyper-converged-system"},"515":{"id":515,"title":"Tower Server","description":"A tower server is a computer that is built in an upright cabinet that stands alone and that is designed to function as a server. The cabinet is known as a tower, and multiple tower servers can work simultaneously for different tasks and processes. Tower servers are popular owing to the scalability and reliability features since unlimited servers can be added to the existing network largely because of the independent nature of the individual tower servers.\r\nTower servers support most basic applications such as system management, file management, print collaboration, ER applications, distribution and system security.\r\nThere are certain advantages in using tower servers. A tower server is robust and simple in nature. As overall component density is low, easier cooling is possible in tower servers. Possible damage, overheating or downtime can thus be prevented.

Again, the maintenance factor is less when compared to other designs. Easy identification both on the network and physically is possible in tower servers as the data are usually stored in a single tower and not across various devices.\r\nThe cabling involved in tower servers can be complicated, and several tower servers in a single location could be noisy due to the fact that each tower might need a dedicated fan. An individual monitor, mouse or keyboard is required for each tower server, or a keyboard, video and mouse (KVM) switch needs to be available for managing devices using a single set of equipment.

Blade servers have many components removed to save space, minimize power consumption and other considerations, while still having all the functional components to be considered a computer. Unlike a rack-mount server, a blade server needs a blade enclosure, which can hold multiple blade servers, providing services such as power, cooling, networking, various interconnects and management. Together, blades and the blade enclosure form a blade system. Different blade providers have differing principles regarding what to include in the blade itself, and in the blade system as a whole.\r\nIn a standard server-rack configuration, one rack unit or 1U—19 inches (480 mm) wide and 1.75 inches (44 mm) tall—defines the minimum possible size of any equipment. The principal benefit and justification of blade computing relates to lifting this restriction so as to reduce size requirements. The most common computer rack form-factor is 42U high, which limits the number of discrete computer devices directly mountable in a rack to 42 components. Blades do not have this limitation. As of 2014, densities of up to 180 servers per blade system (or 1440 servers per rack) are achievable with blade systems.\r\nEnclosure (or chassis) performs many of the non-core computing services found in most computers. Non-blade systems typically use bulky, hot and space-inefficient components, and may duplicate these across many computers that may or may not perform at capacity. By locating these services in one place and sharing them among the blade computers, the overall utilization becomes higher. The specifics of which services are provided varies by vendor.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Power.</span></span> Computers operate over a range of DC voltages, but utilities deliver power as AC, and at higher voltages than required within computers. Converting this current requires one or more power supply units (or PSUs). To ensure that the failure of one power source does not affect the operation of the computer, even entry-level servers may have redundant power supplies, again adding to the bulk and heat output of the design.\r\nThe blade enclosure's power supply provides a single power source for all blades within the enclosure. This single power source may come as a power supply in the enclosure or as a dedicated separate PSU supplying DC to multiple enclosures. This setup reduces the number of PSUs required to provide a resilient power supply.\r\nThe popularity of blade servers, and their own appetite for power, has led to an increase in the number of rack-mountable uninterruptible power supply (or UPS) units, including units targeted specifically towards blade servers (such as the BladeUPS).\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Cooling.</span></span> During operation, electrical and mechanical components produce heat, which a system must dissipate to ensure the proper functioning of its components. Most blade enclosures, like most computing systems, remove heat by using fans.\r\nA frequently underestimated problem when designing high-performance computer systems involves the conflict between the amount of heat a system generates and the ability of its fans to remove the heat. The blade's shared power and cooling means that it does not generate as much heat as traditional servers. Newer blade-enclosures feature variable-speed fans and control logic, or even liquid cooling systems that adjust to meet the system's cooling requirements.\r\nAt the same time, the increased density of blade-server configurations can still result in higher overall demands for cooling with racks populated at over 50% full. This is especially true with early-generation blades. In absolute terms, a fully populated rack of blade servers is likely to require more cooling capacity than a fully populated rack of standard 1U servers. This is because one can fit up to 128 blade servers in the same rack that will only hold 42 1U rack mount servers.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Networking.</span></span> Blade servers generally include integrated or optional network interface controllers for Ethernet or host adapters for Fibre Channel storage systems or converged network adapter to combine storage and data via one Fibre Channel over Ethernet interface. In many blades at least one interface is embedded on the motherboard and extra interfaces can be added using mezzanine cards.\r\nA blade enclosure can provide individual external ports to which each network interface on a blade will connect. Alternatively, a blade enclosure can aggregate network interfaces into interconnect devices (such as switches) built into the blade enclosure or in networking blades.\r\nBlade servers function well for specific purposes such as web hosting, virtualization, and cluster computing. Individual blades are typically hot-swappable. As users deal with larger and more diverse workloads, they add more processing power, memory and I/O bandwidth to blade servers. Although blade server technology in theory allows for open, cross-vendor system, most users buy modules, enclosures, racks and management tools from the same vendor.\r\nEventual standardization of the technology might result in more choices for consumers; as of 2009 increasing numbers of third-party software vendors have started to enter this growing field.\r\nBlade servers do not, however, provide the answer to every computing problem. One can view them as a form of productized server-farm that borrows from mainframe packaging, cooling, and power-supply technology. Very large computing tasks may still require server farms of blade servers, and because of blade servers' high power density, can suffer even more acutely from the heating, ventilation, and air conditioning problems that affect large conventional server farms.","materialsDescription":" <span style=\"font-weight: bold;\">What is blade server?</span>\r\nA blade server is a server chassis housing multiple thin, modular electronic circuit boards, known as server blades. Each blade is a server in its own right, often dedicated to a single application. The blades are literally servers on a card, containing processors, memory, integrated network controllers, an optional Fiber Channel host bus adaptor (HBA) and other input/output (IO) ports.\r\nBlade servers allow more processing power in less rack space, simplifying cabling and reducing power consumption. According to a SearchWinSystems.com article on server technology, enterprises moving to blade servers can experience as much as an 85% reduction in cabling for blade installations over conventional 1U or tower servers. With so much less cabling, IT administrators can spend less time managing the infrastructure and more time ensuring high availability.\r\nEach blade typically comes with one or two local ATA or SCSI drives. For additional storage, blade servers can connect to a storage pool facilitated by a network-attached storage (NAS), Fiber Channel, or iSCSI storage-area network (SAN). The advantage of blade servers comes not only from the consolidation benefits of housing several servers in a single chassis, but also from the consolidation of associated resources (like storage and networking equipment) into a smaller architecture that can be managed through a single interface.\r\nA blade server is sometimes referred to as a high-density server and is typically used in a clustering of servers that are dedicated to a single task, such as:\r\n<ul><li>File sharing</li><li>Web page serving and caching</li><li>SSL encrypting of Web communication</li><li>The transcoding of Web page content for smaller displays</li><li>Streaming audio and video content</li></ul>\r\nLike most clustering applications, blade servers can also be managed to include load balancing and failover capabilities.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Blade_System.png","alias":"blade-system"},"521":{"id":521,"title":"Mission Critical Server","description":" Mission-critical refers to any factor of a system (equipment, process, procedure, software, etc.) whose failure will result in the failure of business operations.

By creating a single point of defense and providing a single console, UTM solutions make dealing with varied threats much easier.\r\nWhile unified threat management solutions do solve some network security issues, they aren't without some drawbacks, with the biggest one being that the single point of defense that an UTM appliance provides also creates a single point of failure.

They can also be used to improve the efficiencies and quality in other less essential (but some would say very important!) real-world processes such as snowmaking for ski resorts and beer brewing. SCADA is one of the most common types of industrial control systems (ICS).\r\nThese networks, just like any other network, are under threat from cyber-attacks that could bring down any part of the nation's critical infrastructure quickly and with dire consequences if the right security is not in place. Capital expenditure is another key concern; SCADA systems can cost an organization from tens of thousands to millions of dollars. For these reasons, it is essential that organizations implement robust SCADA security measures to protect their infrastructure and the millions of people that would be affected by the disruption caused by an external attack or internal error.\r\nSCADA security has evolved dramatically in recent years.

This includes mobile SCADA applications that are used to monitor and manage SCADA systems.\r\n<span style=\"font-weight: bold;\">Terrorists.</span> Where hackers are usually motivated by sordid gain, terrorists are driven by the desire to cause as much mayhem and damage as possible.\r\n<span style=\"font-weight: bold;\">Employees.</span> Insider threats can be just as damaging as external threats. From human error to a disgruntled employee or contractor, it is essential that SCADA security addresses these risks.\r\nManaging today's SCADA networks can be a challenge without the right security precautions in place. Many networks are still without the necessary detection and monitoring systems and this leaves them vulnerable to attack. Because SCADA network attacks exploit both cyber and physical vulnerabilities, it is critical to align cybersecurity measures accordingly.","materialsDescription":"<span style=\"font-weight: bold;\">What is the difference between ICS/SCADA cybersecurity and information security?</span>\r\nAutomated process control systems (SCADA) have a lot of differences from “traditional” corporate information systems: from the destination, specific data transfer protocols and equipment used and ending with the environment in which they operate. In corporate networks and systems, as a rule, the main protected resource is information that is processed, transmitted and stored in automated systems, and the main goal is to ensure its confidentiality. In ICS, the protected resource, first of all, is the technological process itself, and the main goal is to ensure its continuity (accessibility of all nodes) and integrity (including information transmitted between the nodes of the ICS). Moreover, the field of potential risks and threats to ICS, in comparison with corporate systems, expands with risks of potential damage to life and health of personnel and the public, damage to the environment and infrastructure. That is why it is incorrect to talk about “information security” in relation to ICS/SCADA. In English sources, the term “cybersecurity” is used for this, a direct translation of which (cybersecurity) is increasingly found in our market in relation to the protection of process control systems.\r\n<span style=\"font-weight: bold;\">Is it really necessary?</span>\r\nIt is necessary. There are a number of myths about process control systems, for example: “process control systems are completely isolated from the outside world”, “process control systems are too specific for someone to crack”, “process control systems are reliably protected by the developer”, or even “No one will ever try us, hacking us is not interesting. ” All this is no longer true. Many modern distributed process control systems have one or another connection with the corporate network, even if the system owners are unaware of this. Communication with the outside world greatly simplifies the task of the attacker, but does not remain the only possible option. Automated process control software and data transfer protocols are, as a rule, very, very insecure against cyber threats. This is evidenced by numerous articles and reports of experts involved in the study of the protection of industrial control systems and penetration tests. The PHDays III section on hacking automated process control systems impressed even ardent skeptics. Well, and, of course, the argument “they have NOT attacked us, therefore they will not” - can hardly be considered seriously. Everyone has heard about Stuxnet, which dispelled almost all the myths about the safety of ICS at once.\r\n<span style=\"font-weight: bold;\">Who needs this?</span>\r\nWith the phrase ICS/SCADA, most imagine huge plants, automated CNC machines or something similar. However, the application of process control systems is not limited to these objects - in the modern age of automation, process control systems are used everywhere: from large production facilities, the oil and gas industry, transport management to smart home systems. And, by the way, with the protection of the latter, as a rule, everything can be much worse, because the developer silently and imperceptibly shifts responsibility to the shoulders of the user.\r\nOf course, some of the objects with automated process control systems are more interesting for attackers, others less. But, given the ever-growing number of vulnerabilities discovered and published in the ICS, the spread of "exclusive" (written for specific protocols and ICS software) malware, considering your system safe "by default" is unreasonable.\r\n<span style=\"font-weight: bold;\">Are ICS and SCADA the same thing?</span>\r\nNo. SCADA systems (supervisory control and data acquisition, supervisory control and data collection) are part of the control system. Usually, a SCADA system means centralized control and management systems with the participation of a person as a whole system or a complex of industrial control systems. SCADA is the central link between people (human-machine interfaces) and PLC levels (programmable logic controller) or RTU (remote terminal unit).\r\n<span style=\"font-weight: bold;\">What is ICS/SCADA cybersecurity?</span>\r\nIn fact, ICS cybersecurity is a process similar to “information security” in a number of properties, but very different in details. And the devil, as you know, lies in them. ICS/SCADA also has similar information security-related processes: asset inventory, risk analysis and assessment, threat analysis, security management, change management, incident response, continuity, etc. But these processes themselves are different.<br />The cyber security of ICSs has the same basic target qualities - confidentiality, integrity and accessibility, but the significance and point of application for them are completely different. It should be remembered that in ICS/SCADA we, first of all, protect the technological process. Beyond this - from the risks of damage to human health and life and the environment.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_SCADA_Cyber_Security.png","alias":"icsscada-cyber-security"}},"branches":"Information Technology","companySizes":"More than 2000 Employees","companyUrl":"www.dell.com","countryCodes":[],"certifications":[{"id":454,"company_id":169,"title":"Dell Certified Professional PowerEdge","type":"technical"},{"id":455,"company_id":169,"title":"Dell Certified Associate PowerEdge","type":"technical"},{"id":456,"company_id":169,"title":"Dell Certified Professional SC Series","type":"technical"},{"id":457,"company_id":169,"title":"Dell Certified Professional PS Series","type":"technical"},{"id":458,"company_id":169,"title":"Dell Certified Professional Networking","type":"technical"}],"isSeller":true,"isSupplier":false,"isVendor":true,"presenterCodeLng":"","seo":{"title":"DELL","keywords":"States, that, United, Texas, develops, Rock, repairs, services","description":"Dell Inc. is an American privately owned multinational computer technology company based in Round Rock, Texas, United States, that develops, sells, repairs, and supports computers and services.","og:title":"DELL","og:description":"Dell Inc. is an American privately owned multinational computer technology company based in Round Rock, Texas, United States, that develops, sells, repairs, and supports computers and services.","og:image":"https://old.roi4cio.com/uploads/roi/company/dell_logo.png"},"eventUrl":"","vendorPartners":[],"supplierPartners":[{"supplier":"ISSP","partnershipLevel":"Registered","countries":"","partnersType":""},{"supplier":"MUK (supplier)","partnershipLevel":"Distributor","countries":"","partnersType":""},{"supplier":"ERC (Electronic Resource Company)","partnershipLevel":"Distributor","countries":"","partnersType":""},{"supplier":"ASBIS","partnershipLevel":"","countries":"","partnersType":""},{"supplier":"MTI","partnershipLevel":"Distributor","countries":"","partnersType":""},{"supplier":"ELKO Ukraine","partnershipLevel":"Distributor","countries":"","partnersType":""},{"supplier":"JT-Computer Soft- u.

A business typically relies heavily upon the applications, services and data contained within a data center, making it a focal point and critical asset for everyday operations.\r\nData centers are not a single thing, but rather, a conglomeration of elements. At a minimum, data centers serve as the principal repositories for all manner of IT equipment, including servers, storage subsystems, networking switches, routers and firewalls, as well as the cabling and physical racks used to organize and interconnect the IT equipment. A data center must also contain an adequate infrastructure, such as power distribution and supplemental power subsystems, including electrical switching; uninterruptable power supplies; backup generators and so on; ventilation and data center cooling systems, such as computer room air conditioners; and adequate provisioning for network carrier (telco) connectivity. All of this demands a physical facility with physical security and sufficient physical space to house the entire collection of infrastructure and equipment.","materialsDescription":" <span style=\"font-weight: bold;\">What are the requirements for modern data centers?</span>\r\nModernization and data center transformation enhances performance and energy efficiency.\r\nInformation security is also a concern, and for this reason a data center has to offer a secure environment which minimizes the chances of a security breach. A data center must therefore keep high standards for assuring the integrity and functionality of its hosted computer environment.\r\nIndustry research company International Data Corporation (IDC) puts the average age of a data center at nine years old. Gartner, another research company, says data centers older than seven years are obsolete. The growth in data (163 zettabytes by 2025) is one factor driving the need for data centers to modernize.\r\nFocus on modernization is not new: Concern about obsolete equipment was decried in 2007, and in 2011 Uptime Institute was concerned about the age of the equipment therein. By 2018 concern had shifted once again, this time to the age of the staff: "data center staff are aging faster than the equipment."\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Meeting standards for data centers</span></span>\r\nThe Telecommunications Industry Association's Telecommunications Infrastructure Standard for Data Centers specifies the minimum requirements for telecommunications infrastructure of data centers and computer rooms including single tenant enterprise data centers and multi-tenant Internet hosting data centers. The topology proposed in this document is intended to be applicable to any size data center.\r\nTelcordia GR-3160, NEBS Requirements for Telecommunications Data Center Equipment and Spaces, provides guidelines for data center spaces within telecommunications networks, and environmental requirements for the equipment intended for installation in those spaces. These criteria were developed jointly by Telcordia and industry representatives. They may be applied to data center spaces housing data processing or Information Technology (IT) equipment. The equipment may be used to:\r\n<ul><li>Operate and manage a carrier's telecommunication network</li><li>Provide data center based applications directly to the carrier's customers</li><li>Provide hosted applications for a third party to provide services to their customers</li><li>Provide a combination of these and similar data center applications</li></ul>\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Data center transformation</span></span>\r\nData center transformation takes a step-by-step approach through integrated projects carried out over time. This differs from a traditional method of data center upgrades that takes a serial and siloed approach. The typical projects within a data center transformation initiative include standardization/consolidation, virtualization, automation and security.\r\n<ul><li>Standardization/consolidation: Reducing the number of data centers and avoiding server sprawl (both physical and virtual) often includes replacing aging data center equipment, and is aided by standardization.</li><li>Virtualization: Lowers capital and operational expenses, reduce energy consumption. Virtualized desktops can be hosted in data centers and rented out on a subscription basis. Investment bank Lazard Capital Markets estimated in 2008 that 48 percent of enterprise operations will be virtualized by 2012. Gartner views virtualization as a catalyst for modernization.</li><li>Automating: Automating tasks such as provisioning, configuration, patching, release management and compliance is needed, not just when facing fewer skilled IT workers.</li><li>Securing: Protection of virtual systems is integrated with existing security of physical infrastructures.</li></ul>\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Machine room</span></span>\r\nThe term "Machine Room" is at times used to refer to the large room within a Data Center where the actual Central Processing Unit is located; this may be separate from where high-speed printers are located. Air conditioning is most important in the machine room.\r\nAside from air-conditioning, there must be monitoring equipment, one type of which is to detect water prior to flood-level situations. One company, for several decades, has had share-of-mind: Water Alert. The company, as of 2018, has 2 competing manufacturers (Invetex, Hydro-Temp) and 3 competing distributors (Longden,Northeast Flooring, Slayton).

By contrast, software is instructions that can be stored and run by hardware. Hardware is so-termed because it is "hard" or rigid with respect to changes or modifications; whereas software is "soft" because it is easy to update or change. Intermediate between software and hardware is "firmware", which is software that is strongly coupled to the particular hardware of a computer system and thus the most difficult to change but also among the most stable with respect to consistency of interface. The progression from levels of "hardness" to "softness" in computer systems parallels a progression of layers of abstraction in computing.\r\nHardware is typically directed by the software to execute any command or instruction. A combination of hardware and software forms a usable computing system, although other systems exist with only hardware components.\r\nThe template for all modern computers is the Von Neumann architecture, detailed in a 1945 paper by Hungarian mathematician John von Neumann. This describes a design architecture for an electronic digital computer with subdivisions of a processing unit consisting of an arithmetic logic unit and processor registers, a control unit containing an instruction register and program counter, a memory to store both data and instructions, external mass storage, and input and output mechanisms. The meaning of the term has evolved to mean a stored-program computer in which an instruction fetch and a data operation cannot occur at the same time because they share a common bus. This is referred to as the Von Neumann bottleneck and often limits the performance of the system.","materialsDescription":" <span style=\"font-weight: bold; \">What does Hardware (H/W) mean?</span>\r\nHardware (H/W), in the context of technology, refers to the physical elements that make up a computer or electronic system and everything else involved that is physically tangible. This includes the monitor, hard drive, memory and CPU. Hardware works hand-in-hand with firmware and software to make a computer function.\r\n<span style=\"font-weight: bold; \">What are the types of computer systems?</span>\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Personal computer</span></span>\r\nThe personal computer, also known as the PC, is one of the most common types of computer due to its versatility and relatively low price. Laptops are generally very similar, although they may use lower-power or reduced size components, thus lower performance.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Case</span></span>\r\nThe computer case encloses and holds most of the components of the system. It provides mechanical support and protection for internal elements such as the motherboard, disk drives, and power supplies, and controls and directs the flow of cooling air over internal components. The case is also part of the system to control electromagnetic interference radiated by the computer, and protects internal parts from electrostatic discharge. Large tower cases provide extra internal space for multiple disk drives or other peripherals and usually stand on the floor, while desktop cases provide less expansion room. All-in-one style designs include a video display built into the same case. Portable and laptop computers require cases that provide impact protection for the unit. A current development in laptop computers is a detachable keyboard, which allows the system to be configured as a touch-screen tablet. Hobbyists may decorate the cases with colored lights, paint, or other features, in an activity called case modding.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Power supply</span></span>\r\nA power supply unit (PSU) converts alternating current (AC) electric power to low-voltage direct current (DC) power for the internal components of the computer. Laptops are capable of running from a built-in battery, normally for a period of hours. The PSU typically uses a switched-mode power supply (SMPS), with power MOSFETs (power metal–oxide–semiconductor field-effect transistors) used in the converters and regulator circuits of the SMPS.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Motherboard</span></span>\r\nThe motherboard is the main component of a computer. It is a board with integrated circuitry that connects the other parts of the computer including the CPU, the RAM, the disk drives (CD, DVD, hard disk, or any others) as well as any peripherals connected via the ports or the expansion slots. The integrated circuit (IC) chips in a computer typically contain billions of tiny metal–oxide–semiconductor field-effect transistors (MOSFETs).\r\nComponents directly attached to or to part of the motherboard include:\r\n<ul><li><span style=\"font-weight: bold; \">The CPU (central processing unit)</span>, which performs most of the calculations which enable a computer to function, and is referred to as the brain of the computer which get a hold of program instruction from random-access memory (RAM), interprets and processes it and then send it backs to computer result so that the relevant components can carry out the instructions. The CPU is a microprocessor, which is fabricated on a metal–oxide–semiconductor (MOS) integrated circuit (IC) chip. It is usually cooled by a heat sink and fan, or water-cooling system. Most newer CPU include an on-die graphics processing unit (GPU). The clock speed of CPU governs how fast it executes instructions, and is measured in GHz; typical values lie between 1 GHz and 5 GHz. Many modern computers have the option to overclock the CPU which enhances performance at the expense of greater thermal output and thus a need for improved cooling.</li><li><span style=\"font-weight: bold; \">The chipset</span>, which includes the north bridge, mediates communication between the CPU and the other components of the system, including main memory; as well as south bridge, which is connected to the north bridge, and supports auxiliary interfaces and buses; and, finally, a Super I/O chip, connected through the south bridge, which supports the slowest and most legacy components like serial ports, hardware monitoring and fan control.</li><li><span style=\"font-weight: bold; \">Random-access memory (RAM)</span>, which stores the code and data that are being actively accessed by the CPU. For example, when a web browser is opened on the computer it takes up memory; this is stored in the RAM until the web browser is closed. It is typically a type of dynamic RAM (DRAM), such as synchronous DRAM (SDRAM), where MOS memory chips store data on memory cells consisting of MOSFETs and MOS capacitors. RAM usually comes on dual in-line memory modules (DIMMs) in the sizes of 2GB, 4GB, and 8GB, but can be much larger.</li><li><span style=\"font-weight: bold; \">Read-only memory (ROM)</span>, which stores the BIOS that runs when the computer is powered on or otherwise begins execution, a process known as Bootstrapping, or "booting" or "booting up". The ROM is typically a nonvolatile BIOS memory chip, which stores data on floating-gate MOSFET memory cells.</li><li><span style=\"font-weight: bold; \">The BIOS (Basic Input Output System)</span> includes boot firmware and power management firmware. Newer motherboards use Unified Extensible Firmware Interface (UEFI) instead of BIOS.</li><li><span style=\"font-weight: bold; \">Buses</span> that connect the CPU to various internal components and to expand cards for graphics and sound.</li><li><span style=\"font-weight: bold; \">The CMOS</span> (complementary MOS) battery, which powers the CMOS memory for date and time in the BIOS chip. This battery is generally a watch battery.</li><li><span style=\"font-weight: bold; \">The video card</span> (also known as the graphics card), which processes computer graphics. More powerful graphics cards are better suited to handle strenuous tasks, such as playing intensive video games or running computer graphics software. A video card contains a graphics processing unit (GPU) and video memory (typically a type of SDRAM), both fabricated on MOS integrated circuit (MOS IC) chips.</li><li><span style=\"font-weight: bold; \">Power MOSFETs</span> make up the voltage regulator module (VRM), which controls how much voltage other hardware components receive.</li></ul>\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Expansion cards</span></span>\r\nAn expansion card in computing is a printed circuit board that can be inserted into an expansion slot of a computer motherboard or backplane to add functionality to a computer system via the expansion bus. Expansion cards can be used to obtain or expand on features not offered by the motherboard.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Storage devices</span></span>\r\nA storage device is any computing hardware and digital media that is used for storing, porting and extracting data files and objects. It can hold and store information both temporarily and permanently, and can be internal or external to a computer, server or any similar computing device. Data storage is a core function and fundamental component of computers.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Fixed media</span></span>\r\nData is stored by a computer using a variety of media. Hard disk drives (HDDs) are found in virtually all older computers, due to their high capacity and low cost, but solid-state drives (SSDs) are faster and more power efficient, although currently more expensive than hard drives in terms of dollar per gigabyte, so are often found in personal computers built post-2007. SSDs use flash memory, which stores data on MOS memory chips consisting of floating-gate MOSFET memory cells. Some systems may use a disk array controller for greater performance or reliability.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Removable media</span></span>\r\nTo transfer data between computers, an external flash memory device (such as a memory card or USB flash drive) or optical disc (such as a CD-ROM, DVD-ROM or BD-ROM) may be used. Their usefulness depends on being readable by other systems; the majority of machines have an optical disk drive (ODD), and virtually all have at least one Universal Serial Bus (USB) port.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Input and output peripherals</span></span>\r\nInput and output devices are typically housed externally to the main computer chassis. The following are either standard or very common to many computer systems.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Input</span></span>\r\nInput devices allow the user to enter information into the system, or control its operation. Most personal computers have a mouse and keyboard, but laptop systems typically use a touchpad instead of a mouse. Other input devices include webcams, microphones, joysticks, and image scanners.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Output device</span></span>\r\nOutput devices display information in a human readable form. Such devices could include printers, speakers, monitors or a Braille embosser.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Mainframe computer</span></span>\r\nA mainframe computer is a much larger computer that typically fills a room and may cost many hundreds or thousands of times as much as a personal computer. They are designed to perform large numbers of calculations for governments and large enterprises.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Departmental computing</span></span>\r\nIn the 1960s and 1970s, more and more departments started to use cheaper and dedicated systems for specific purposes like process control and laboratory automation.\r\n<span style=\"font-style: italic;\"><span style=\"font-weight: bold;\">Supercomputer</span></span>\r\nA supercomputer is superficially similar to a mainframe, but is instead intended for extremely demanding computational tasks. As of June 2018, the fastest supercomputer on the TOP500supercomputer list is the Summit, in the United States, with a LINPACK benchmarkscore of 122.3 PFLOPS Light, by around 29 PFLOPS.\r\nThe term supercomputer does not refer to a specific technology. Rather it indicates the fastest computations available at any given time. In mid 2011, the fastest supercomputers boasted speeds exceeding one petaflop, or 1 quadrillion (10^15 or 1,000 trillion) floating point operations per second. Supercomputers are fast but extremely costly, so they are generally used by large organizations to execute computationally demanding tasks involving large data sets. Supercomputers typically run military and scientific applications. Although costly, they are also being used for commercial applications where huge amounts of data must be analyzed. For example, large banks employ supercomputers to calculate the risks and returns of various investment strategies, and healthcare organizations use them to analyze giant databases of patient data to determine optimal treatments for various diseases and problems incurring to the country.

This architecture is called the client–server model, and a single overall computation is distributed across multiple processes or devices. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients, or performing computation for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.\r\nClient–server systems are today most frequently implemented by (and often identified with) the request–response model: a client sends a request to the server, which performs some action and sends a response back to the client, typically with a result or acknowledgement. Designating a computer as "server-class hardware" implies that it is specialized for running servers on it. This often implies that it is more powerful and reliable than standard personal computers, but alternatively, large computing clusters may be composed of many relatively simple, replaceable server components.\r\nStrictly speaking, the term server refers to a computer program or process (running program). Through metonymy, it refers to a device used for (or a device dedicated to) running one or several server programs. On a network, such a device is called a host. In addition to server, the words serve and service (as noun and as verb) are frequently used, though servicer and servant are not. The word service (noun) may refer to either the abstract form of functionality, e.g. Web service. Alternatively, it may refer to a computer program that turns a computer into a server, e.g. Windows service. Originally used as "servers serve users" (and "users use servers"), in the sense of "obey", today one often says that "servers serve data", in the same sense as "give". For instance, web servers "serve web pages to users" or "service their requests".\r\nThe server is part of the client–server model; in this model, a server serves data for clients. The nature of communication between a client and server is request and response. This is in contrast with peer-to-peer model in which the relationship is on-demand reciprocation. In principle, any computerized process that can be used or called by another process (particularly remotely, particularly to share a resource) is a server, and the calling process or processes is a client. Thus any general purpose computer connected to a network can host servers. For example, if files on a device are shared by some process, that process is a file server. Similarly, web server software can run on any capable computer, and so a laptop or a personal computer can host a web server.\r\nWhile request–response is the most common client–server design, there are others, such as the publish–subscribe pattern. In the publish–subscribe pattern, clients register with a pub–sub server, subscribing to specified types of messages; this initial registration may be done by request–response. Thereafter, the pub–sub server forwards matching messages to the clients without any further requests: the server pushes messages to the client, rather than the client pulling messages from the server as in request–response.","materialsDescription":" <span style=\"font-weight: bold;\">What is a server?</span>\r\nA server is a software or hardware device that accepts and responds to requests made over a network. The device that makes the request, and receives a response from the server, is called a client. On the Internet, the term "server" commonly refers to the computer system which receives a request for a web document and sends the requested information to the client.\r\n<span style=\"font-weight: bold;\">What are they used for?</span>\r\nServers are used to manage network resources. For example, a user may set up a server to control access to a network, send/receive an e-mail, manage print jobs, or host a website. They are also proficient at performing intense calculations. Some servers are committed to a specific task, often referred to as dedicated. However, many servers today are shared servers which can take on the responsibility of e-mail, DNS, FTP, and even multiple websites in the case of a web server.\r\n<span style=\"font-weight: bold;\">Why are servers always on?</span>\r\nBecause they are commonly used to deliver services that are constantly required, most servers are never turned off. Consequently, when servers fail, they can cause the network users and company many problems. To alleviate these issues, servers are commonly set up to be fault-tolerant.\r\n<span style=\"font-weight: bold;\">What are the examples of servers?</span>\r\nThe following list contains links to various server types:\r\n<ul><li>Application server;</li><li>Blade server;</li><li>Cloud server;</li><li>Database server;</li><li>Dedicated server;</li><li>Domain name service;</li><li>File server;</li><li>Mail server;</li><li>Print server;</li><li>Proxy server;</li><li>Standalone server;</li><li>Web server.</li></ul>\r\n<span style=\"font-weight: bold;\">How do other computers connect to a server?</span>\r\nWith a local network, the server connects to a router or switch that all other computers on the network use. Once connected to the network, other computers can access that server and its features. For example, with a web server, a user could connect to the server to view a website, search, and communicate with other users on the network.\r\nAn Internet server works the same way as a local network server, but on a much larger scale. The server is assigned an IP address by InterNIC, or by a web host.\r\nUsually, users connect to a server using its domain name, which is registered with a domain name registrar. When users connect to the domain name (such as "computerhope.com"), the name is automatically translated to the server's IP address by a DNS resolver.\r\nThe domain name makes it easier for users to connect to the server because the name is easier to remember than an IP address. Also, domain names enable the server operator to change the IP address of the server without disrupting the way that users access the server. The domain name can always remain the same, even if the IP address changes.\r\n<span style=\"font-weight: bold;\">Where are servers stored?</span>\r\nIn a business or corporate environment, a server and other network equipment are often stored in a closet or glasshouse. These areas help isolate sensitive computers and equipment from people who should not have access to them.\r\nServers that are remote or not hosted on-site are located in a data center. With these types of servers, the hardware is managed by another company and configured remotely by you or your company.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Server.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},{"id":769,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/Dell_Wyse_3040_tonkii_klient.jpg","logo":true,"scheme":false,"title":"Dell Wyse 3040 Thin Client","vendorVerified":0,"rating":"2.00","implementationsCount":0,"suppliersCount":0,"supplierPartnersCount":15,"alias":"dell-wyse-3040-thin-client","companyTitle":"DELL","companyTypes":["vendor"],"companyId":169,"companyAlias":"dell","description":"Efficient and effective.\r\nWyse 3040 Thin Client - Simplified setup<span style=\"white-space:pre\">\t</span>Simplified setup: With simplified automatic setup, configuration and management, the Wyse 3040 can be deployed right out-of-the box.

Rackmount servers are typically easier for administrators to manage due to proximity, modularity and better cable management. Lockable rack cabinet doors and steel server front panels provide an additional level of physical security. Additionally, rack unit designed servers are better able to keep the server components cool than traditional tower form factor. Industry standard 19-inch racks will allow you to easily expand your business without taking up more valuable floor space.\r\nThere is a lot of thought that needs to go into which size rack server is best bet for your project. Both current requirements and future expansion plans need to be taken into account to ensure your server remains capable in the future.\r\nBoth large and small projects can be built on the 1U server platform. "U" stands for unit, “unit”, and this means thickness: server rack 1U = 1.75 inches or 44 mm wide. A reasonable amount of storage can fit within a 1U, processing power has no limits, and some models even allow up to two PCI-Express cards. Modern computer hardware uses much less power than it ever has in the past, which means less heat generation. Some 1U servers to still produce some acoustic noise, but is nowhere near the level of needing earmuffs like the old days. The only reason to go up in size is for additional expansion options.\r\n2U models allow for multiple "low-profile" PCI-Express cards while keeping a compact form factor and also providing some additional storage space. If the plan is to use multiple full height cards, then 3U or 4U servers should be the focus. The 4U models are very popular and offer flexible options. The 3U models do have limitations on expansion card compatibility and are really only for situations where rack space needs to be absolutely optimized (14x3U servers or 10x4U servers can fit in a 42u rack).","materialsDescription":"<span style=\"font-weight: bold;\">What is a ‘rack unit’?</span>\r\nA rack unit is the designated unit of measurement used when describing or quantifying the vertical space you have available in any equipment rack. One unit is equal to 1.75 inches, or 4.45 centimeters. Any equipment that has the ability to be mounted onto a rack is generally designed in a standard size to fit into many different server rack heights. It’s actually been standardized by the Electronic Industries Alliance (EIA).

Some cabinet manufacturers construct side panel ventilation instead of front and back ventilation, but experts say it’s inadequate for rack mount servers. This can be especially dangerous if more than one cabinet is being set up at once.

For instance, web servers "serve web pages to users" or "service their requests".\r\nThe server is part of the client–server model; in this model, a server serves data for clients. The nature of communication between a client and server is request and response. This is in contrast with peer-to-peer model in which the relationship is on-demand reciprocation. In principle, any computerized process that can be used or called by another process (particularly remotely, particularly to share a resource) is a server, and the calling process or processes is a client. Thus any general purpose computer connected to a network can host servers. For example, if files on a device are shared by some process, that process is a file server. Similarly, web server software can run on any capable computer, and so a laptop or a personal computer can host a web server.\r\nWhile request–response is the most common client–server design, there are others, such as the publish–subscribe pattern. In the publish–subscribe pattern, clients register with a pub–sub server, subscribing to specified types of messages; this initial registration may be done by request–response. Thereafter, the pub–sub server forwards matching messages to the clients without any further requests: the server pushes messages to the client, rather than the client pulling messages from the server as in request–response.","materialsDescription":" <span style=\"font-weight: bold;\">What is a server?</span>\r\nA server is a software or hardware device that accepts and responds to requests made over a network. The device that makes the request, and receives a response from the server, is called a client. On the Internet, the term "server" commonly refers to the computer system which receives a request for a web document and sends the requested information to the client.\r\n<span style=\"font-weight: bold;\">What are they used for?</span>\r\nServers are used to manage network resources. For example, a user may set up a server to control access to a network, send/receive an e-mail, manage print jobs, or host a website. They are also proficient at performing intense calculations. Some servers are committed to a specific task, often referred to as dedicated. However, many servers today are shared servers which can take on the responsibility of e-mail, DNS, FTP, and even multiple websites in the case of a web server.\r\n<span style=\"font-weight: bold;\">Why are servers always on?</span>\r\nBecause they are commonly used to deliver services that are constantly required, most servers are never turned off. Consequently, when servers fail, they can cause the network users and company many problems. To alleviate these issues, servers are commonly set up to be fault-tolerant.\r\n<span style=\"font-weight: bold;\">What are the examples of servers?</span>\r\nThe following list contains links to various server types:\r\n<ul><li>Application server;</li><li>Blade server;</li><li>Cloud server;</li><li>Database server;</li><li>Dedicated server;</li><li>Domain name service;</li><li>File server;</li><li>Mail server;</li><li>Print server;</li><li>Proxy server;</li><li>Standalone server;</li><li>Web server.</li></ul>\r\n<span style=\"font-weight: bold;\">How do other computers connect to a server?</span>\r\nWith a local network, the server connects to a router or switch that all other computers on the network use. Once connected to the network, other computers can access that server and its features. For example, with a web server, a user could connect to the server to view a website, search, and communicate with other users on the network.\r\nAn Internet server works the same way as a local network server, but on a much larger scale. The server is assigned an IP address by InterNIC, or by a web host.\r\nUsually, users connect to a server using its domain name, which is registered with a domain name registrar. When users connect to the domain name (such as "computerhope.com"), the name is automatically translated to the server's IP address by a DNS resolver.\r\nThe domain name makes it easier for users to connect to the server because the name is easier to remember than an IP address. Also, domain names enable the server operator to change the IP address of the server without disrupting the way that users access the server. The domain name can always remain the same, even if the IP address changes.\r\n<span style=\"font-weight: bold;\">Where are servers stored?</span>\r\nIn a business or corporate environment, a server and other network equipment are often stored in a closet or glasshouse. These areas help isolate sensitive computers and equipment from people who should not have access to them.\r\nServers that are remote or not hosted on-site are located in a data center. With these types of servers, the hardware is managed by another company and configured remotely by you or your company.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Server.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},{"id":862,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/IBP_dvoinogo_preobrazovanija_Dell_Smart-UPS.png","logo":true,"scheme":false,"title":"ИБП двойного преобразования Dell Smart-UPS","vendorVerified":0,"rating":"2.00","implementationsCount":0,"suppliersCount":0,"supplierPartnersCount":15,"alias":"ibp-dvoinogo-preobrazovanija-dell-smart-ups","companyTitle":"DELL","companyTypes":["vendor"],"companyId":169,"companyAlias":"dell","description":"Источники бесперебойного питания (ИБП) от Dell гарантируют надежную и эффективную работу ваших ИТ-систем.

Blade servers have many components removed to save space, minimize power consumption and other considerations, while still having all the functional components to be considered a computer. Unlike a rack-mount server, a blade server needs a blade enclosure, which can hold multiple blade servers, providing services such as power, cooling, networking, various interconnects and management. Together, blades and the blade enclosure form a blade system. Different blade providers have differing principles regarding what to include in the blade itself, and in the blade system as a whole.\r\nIn a standard server-rack configuration, one rack unit or 1U—19 inches (480 mm) wide and 1.75 inches (44 mm) tall—defines the minimum possible size of any equipment. The principal benefit and justification of blade computing relates to lifting this restriction so as to reduce size requirements. The most common computer rack form-factor is 42U high, which limits the number of discrete computer devices directly mountable in a rack to 42 components. Blades do not have this limitation. As of 2014, densities of up to 180 servers per blade system (or 1440 servers per rack) are achievable with blade systems.\r\nEnclosure (or chassis) performs many of the non-core computing services found in most computers. Non-blade systems typically use bulky, hot and space-inefficient components, and may duplicate these across many computers that may or may not perform at capacity. By locating these services in one place and sharing them among the blade computers, the overall utilization becomes higher. The specifics of which services are provided varies by vendor.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Power.</span></span> Computers operate over a range of DC voltages, but utilities deliver power as AC, and at higher voltages than required within computers. Converting this current requires one or more power supply units (or PSUs). To ensure that the failure of one power source does not affect the operation of the computer, even entry-level servers may have redundant power supplies, again adding to the bulk and heat output of the design.\r\nThe blade enclosure's power supply provides a single power source for all blades within the enclosure. This single power source may come as a power supply in the enclosure or as a dedicated separate PSU supplying DC to multiple enclosures. This setup reduces the number of PSUs required to provide a resilient power supply.\r\nThe popularity of blade servers, and their own appetite for power, has led to an increase in the number of rack-mountable uninterruptible power supply (or UPS) units, including units targeted specifically towards blade servers (such as the BladeUPS).\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Cooling.</span></span> During operation, electrical and mechanical components produce heat, which a system must dissipate to ensure the proper functioning of its components. Most blade enclosures, like most computing systems, remove heat by using fans.\r\nA frequently underestimated problem when designing high-performance computer systems involves the conflict between the amount of heat a system generates and the ability of its fans to remove the heat. The blade's shared power and cooling means that it does not generate as much heat as traditional servers. Newer blade-enclosures feature variable-speed fans and control logic, or even liquid cooling systems that adjust to meet the system's cooling requirements.\r\nAt the same time, the increased density of blade-server configurations can still result in higher overall demands for cooling with racks populated at over 50% full. This is especially true with early-generation blades. In absolute terms, a fully populated rack of blade servers is likely to require more cooling capacity than a fully populated rack of standard 1U servers. This is because one can fit up to 128 blade servers in the same rack that will only hold 42 1U rack mount servers.\r\n<span style=\"font-style: italic; \"><span style=\"font-weight: bold; \">Networking.</span></span> Blade servers generally include integrated or optional network interface controllers for Ethernet or host adapters for Fibre Channel storage systems or converged network adapter to combine storage and data via one Fibre Channel over Ethernet interface. In many blades at least one interface is embedded on the motherboard and extra interfaces can be added using mezzanine cards.\r\nA blade enclosure can provide individual external ports to which each network interface on a blade will connect. Alternatively, a blade enclosure can aggregate network interfaces into interconnect devices (such as switches) built into the blade enclosure or in networking blades.\r\nBlade servers function well for specific purposes such as web hosting, virtualization, and cluster computing. Individual blades are typically hot-swappable. As users deal with larger and more diverse workloads, they add more processing power, memory and I/O bandwidth to blade servers. Although blade server technology in theory allows for open, cross-vendor system, most users buy modules, enclosures, racks and management tools from the same vendor.\r\nEventual standardization of the technology might result in more choices for consumers; as of 2009 increasing numbers of third-party software vendors have started to enter this growing field.\r\nBlade servers do not, however, provide the answer to every computing problem. One can view them as a form of productized server-farm that borrows from mainframe packaging, cooling, and power-supply technology. Very large computing tasks may still require server farms of blade servers, and because of blade servers' high power density, can suffer even more acutely from the heating, ventilation, and air conditioning problems that affect large conventional server farms.","materialsDescription":" <span style=\"font-weight: bold;\">What is blade server?</span>\r\nA blade server is a server chassis housing multiple thin, modular electronic circuit boards, known as server blades. Each blade is a server in its own right, often dedicated to a single application. The blades are literally servers on a card, containing processors, memory, integrated network controllers, an optional Fiber Channel host bus adaptor (HBA) and other input/output (IO) ports.\r\nBlade servers allow more processing power in less rack space, simplifying cabling and reducing power consumption. According to a SearchWinSystems.com article on server technology, enterprises moving to blade servers can experience as much as an 85% reduction in cabling for blade installations over conventional 1U or tower servers. With so much less cabling, IT administrators can spend less time managing the infrastructure and more time ensuring high availability.\r\nEach blade typically comes with one or two local ATA or SCSI drives. For additional storage, blade servers can connect to a storage pool facilitated by a network-attached storage (NAS), Fiber Channel, or iSCSI storage-area network (SAN). The advantage of blade servers comes not only from the consolidation benefits of housing several servers in a single chassis, but also from the consolidation of associated resources (like storage and networking equipment) into a smaller architecture that can be managed through a single interface.\r\nA blade server is sometimes referred to as a high-density server and is typically used in a clustering of servers that are dedicated to a single task, such as:\r\n<ul><li>File sharing</li><li>Web page serving and caching</li><li>SSL encrypting of Web communication</li><li>The transcoding of Web page content for smaller displays</li><li>Streaming audio and video content</li></ul>\r\nLike most clustering applications, blade servers can also be managed to include load balancing and failover capabilities.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Blade_System.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},{"id":866,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/DELL_Modulnaja_infrastruktura.png","logo":true,"scheme":false,"title":"DELL

Rackmount servers are typically easier for administrators to manage due to proximity, modularity and better cable management. Lockable rack cabinet doors and steel server front panels provide an additional level of physical security. Additionally, rack unit designed servers are better able to keep the server components cool than traditional tower form factor. Industry standard 19-inch racks will allow you to easily expand your business without taking up more valuable floor space.\r\nThere is a lot of thought that needs to go into which size rack server is best bet for your project. Both current requirements and future expansion plans need to be taken into account to ensure your server remains capable in the future.\r\nBoth large and small projects can be built on the 1U server platform. "U" stands for unit, “unit”, and this means thickness: server rack 1U = 1.75 inches or 44 mm wide. A reasonable amount of storage can fit within a 1U, processing power has no limits, and some models even allow up to two PCI-Express cards. Modern computer hardware uses much less power than it ever has in the past, which means less heat generation. Some 1U servers to still produce some acoustic noise, but is nowhere near the level of needing earmuffs like the old days. The only reason to go up in size is for additional expansion options.\r\n2U models allow for multiple "low-profile" PCI-Express cards while keeping a compact form factor and also providing some additional storage space. If the plan is to use multiple full height cards, then 3U or 4U servers should be the focus. The 4U models are very popular and offer flexible options. The 3U models do have limitations on expansion card compatibility and are really only for situations where rack space needs to be absolutely optimized (14x3U servers or 10x4U servers can fit in a 42u rack).","materialsDescription":"<span style=\"font-weight: bold;\">What is a ‘rack unit’?</span>\r\nA rack unit is the designated unit of measurement used when describing or quantifying the vertical space you have available in any equipment rack. One unit is equal to 1.75 inches, or 4.45 centimeters. Any equipment that has the ability to be mounted onto a rack is generally designed in a standard size to fit into many different server rack heights. It’s actually been standardized by the Electronic Industries Alliance (EIA). The most common heights are between 8U to 50U, but customization is also a viable option if you’re working with nonstandard sizes.\r\n<span style=\"font-weight: bold;\">Are there any specific ventilation requirements with server racks?</span>\r\nOver 65% of IT equipment failures are directly attributed to inadequate, poorly maintained, or failed air conditioning in the server room. So yes, proper ventilation is a critical part of maintaining any data center. Some cabinet manufacturers construct side panel ventilation instead of front and back ventilation, but experts say it’s inadequate for rack mount servers. This can be especially dangerous if more than one cabinet is being set up at once.

Although blade server technology in theory allows for open, cross-vendor system, most users buy modules, enclosures, racks and management tools from the same vendor.\r\nEventual standardization of the technology might result in more choices for consumers; as of 2009 increasing numbers of third-party software vendors have started to enter this growing field.\r\nBlade servers do not, however, provide the answer to every computing problem. One can view them as a form of productized server-farm that borrows from mainframe packaging, cooling, and power-supply technology. Very large computing tasks may still require server farms of blade servers, and because of blade servers' high power density, can suffer even more acutely from the heating, ventilation, and air conditioning problems that affect large conventional server farms.","materialsDescription":" <span style=\"font-weight: bold;\">What is blade server?</span>\r\nA blade server is a server chassis housing multiple thin, modular electronic circuit boards, known as server blades. Each blade is a server in its own right, often dedicated to a single application. The blades are literally servers on a card, containing processors, memory, integrated network controllers, an optional Fiber Channel host bus adaptor (HBA) and other input/output (IO) ports.\r\nBlade servers allow more processing power in less rack space, simplifying cabling and reducing power consumption. According to a SearchWinSystems.com article on server technology, enterprises moving to blade servers can experience as much as an 85% reduction in cabling for blade installations over conventional 1U or tower servers. With so much less cabling, IT administrators can spend less time managing the infrastructure and more time ensuring high availability.\r\nEach blade typically comes with one or two local ATA or SCSI drives. For additional storage, blade servers can connect to a storage pool facilitated by a network-attached storage (NAS), Fiber Channel, or iSCSI storage-area network (SAN). The advantage of blade servers comes not only from the consolidation benefits of housing several servers in a single chassis, but also from the consolidation of associated resources (like storage and networking equipment) into a smaller architecture that can be managed through a single interface.\r\nA blade server is sometimes referred to as a high-density server and is typically used in a clustering of servers that are dedicated to a single task, such as:\r\n<ul><li>File sharing</li><li>Web page serving and caching</li><li>SSL encrypting of Web communication</li><li>The transcoding of Web page content for smaller displays</li><li>Streaming audio and video content</li></ul>\r\nLike most clustering applications, blade servers can also be managed to include load balancing and failover capabilities.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Blade_System.png"},{"id":35,"title":"Server","alias":"server","description":"In computing, a server is a computer program or a device that provides functionality for other programs or devices, called "clients". This architecture is called the client–server model, and a single overall computation is distributed across multiple processes or devices. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients, or performing computation for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers.\r\nClient–server systems are today most frequently implemented by (and often identified with) the request–response model: a client sends a request to the server, which performs some action and sends a response back to the client, typically with a result or acknowledgement. Designating a computer as "server-class hardware" implies that it is specialized for running servers on it. This often implies that it is more powerful and reliable than standard personal computers, but alternatively, large computing clusters may be composed of many relatively simple, replaceable server components.\r\nStrictly speaking, the term server refers to a computer program or process (running program). Through metonymy, it refers to a device used for (or a device dedicated to) running one or several server programs. On a network, such a device is called a host. In addition to server, the words serve and service (as noun and as verb) are frequently used, though servicer and servant are not. The word service (noun) may refer to either the abstract form of functionality, e.g. Web service. Alternatively, it may refer to a computer program that turns a computer into a server, e.g. Windows service. Originally used as "servers serve users" (and "users use servers"), in the sense of "obey", today one often says that "servers serve data", in the same sense as "give". For instance, web servers "serve web pages to users" or "service their requests".\r\nThe server is part of the client–server model; in this model, a server serves data for clients. The nature of communication between a client and server is request and response. This is in contrast with peer-to-peer model in which the relationship is on-demand reciprocation. In principle, any computerized process that can be used or called by another process (particularly remotely, particularly to share a resource) is a server, and the calling process or processes is a client. Thus any general purpose computer connected to a network can host servers. For example, if files on a device are shared by some process, that process is a file server. Similarly, web server software can run on any capable computer, and so a laptop or a personal computer can host a web server.\r\nWhile request–response is the most common client–server design, there are others, such as the publish–subscribe pattern. In the publish–subscribe pattern, clients register with a pub–sub server, subscribing to specified types of messages; this initial registration may be done by request–response. Thereafter, the pub–sub server forwards matching messages to the clients without any further requests: the server pushes messages to the client, rather than the client pulling messages from the server as in request–response.","materialsDescription":" <span style=\"font-weight: bold;\">What is a server?</span>\r\nA server is a software or hardware device that accepts and responds to requests made over a network. The device that makes the request, and receives a response from the server, is called a client. On the Internet, the term "server" commonly refers to the computer system which receives a request for a web document and sends the requested information to the client.\r\n<span style=\"font-weight: bold;\">What are they used for?</span>\r\nServers are used to manage network resources. For example, a user may set up a server to control access to a network, send/receive an e-mail, manage print jobs, or host a website. They are also proficient at performing intense calculations. Some servers are committed to a specific task, often referred to as dedicated. However, many servers today are shared servers which can take on the responsibility of e-mail, DNS, FTP, and even multiple websites in the case of a web server.\r\n<span style=\"font-weight: bold;\">Why are servers always on?</span>\r\nBecause they are commonly used to deliver services that are constantly required, most servers are never turned off. Consequently, when servers fail, they can cause the network users and company many problems. To alleviate these issues, servers are commonly set up to be fault-tolerant.\r\n<span style=\"font-weight: bold;\">What are the examples of servers?</span>\r\nThe following list contains links to various server types:\r\n<ul><li>Application server;</li><li>Blade server;</li><li>Cloud server;</li><li>Database server;</li><li>Dedicated server;</li><li>Domain name service;</li><li>File server;</li><li>Mail server;</li><li>Print server;</li><li>Proxy server;</li><li>Standalone server;</li><li>Web server.</li></ul>\r\n<span style=\"font-weight: bold;\">How do other computers connect to a server?</span>\r\nWith a local network, the server connects to a router or switch that all other computers on the network use. Once connected to the network, other computers can access that server and its features. For example, with a web server, a user could connect to the server to view a website, search, and communicate with other users on the network.\r\nAn Internet server works the same way as a local network server, but on a much larger scale. The server is assigned an IP address by InterNIC, or by a web host.\r\nUsually, users connect to a server using its domain name, which is registered with a domain name registrar. When users connect to the domain name (such as "computerhope.com"), the name is automatically translated to the server's IP address by a DNS resolver.\r\nThe domain name makes it easier for users to connect to the server because the name is easier to remember than an IP address. Also, domain names enable the server operator to change the IP address of the server without disrupting the way that users access the server. The domain name can always remain the same, even if the IP address changes.\r\n<span style=\"font-weight: bold;\">Where are servers stored?</span>\r\nIn a business or corporate environment, a server and other network equipment are often stored in a closet or glasshouse. These areas help isolate sensitive computers and equipment from people who should not have access to them.\r\nServers that are remote or not hosted on-site are located in a data center. With these types of servers, the hardware is managed by another company and configured remotely by you or your company.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Server.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},{"id":869,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/DELL_Upravlenie_klientskimi_sistemami.jpg","logo":true,"scheme":false,"title":"DELL Управление клиентскими системами","vendorVerified":0,"rating":"2.00","implementationsCount":0,"suppliersCount":0,"supplierPartnersCount":15,"alias":"dell-upravlenie-klientskimi-sistemami","companyTitle":"DELL","companyTypes":["vendor"],"companyId":169,"companyAlias":"dell","description":"\r\nУстройства управления Dell KACE K1000\r\nУстройство управления Dell KACE K1000 удовлетворяют все ваши требования к управлению системами — от первоначального развертывания до текущего управления и списания, для 100-20 000 конечных узлов.\r\n\r\nУстройства для развертывания Dell KACE K2000\r\nУстройства для развертывания Dell KACE K2000 удовлетворяют потребности в развертывании систем, включая оценку ресурсов, развертывание ОС, установку приложений, настройку и восстановление.","shortDescription":"С помощью упрощенного комплексного подхода к развертыванию систем организации стремятся сэкономить время и деньги и повысить эффективность работы ИТ-отделов.\r\nЗащита данных\r\nDell KACE K1000\r\nDell KACE K2000","type":null,"isRoiCalculatorAvaliable":false,"isConfiguratorAvaliable":false,"bonus":100,"usingCount":6,"sellingCount":12,"discontinued":0,"rebateForPoc":0,"rebate":0,"seo":{"title":"DELL Управление клиентскими системами","keywords":"Dell, KACE, развертывания, Устройства, управления, удовлетворяют, K2000, K1000","description":"\r\nУстройства управления Dell KACE K1000\r\nУстройство управления Dell KACE K1000 удовлетворяют все ваши требования к управлению системами — от первоначального развертывания до текущего управления и списания, для 100-20 000 конечных узлов.\r\n\r\nУстройства для разве","og:title":"DELL Управление клиентскими системами","og:description":"\r\nУстройства управления Dell KACE K1000\r\nУстройство управления Dell KACE K1000 удовлетворяют все ваши требования к управлению системами — от первоначального развертывания до текущего управления и списания, для 100-20 000 конечных узлов.\r\n\r\nУстройства для разве","og:image":"https://old.roi4cio.com/fileadmin/user_upload/DELL_Upravlenie_klientskimi_sistemami.jpg"},"eventUrl":"","translationId":7017,"dealDetails":null,"roi":null,"price":null,"bonusForReference":null,"templateData":[],"testingArea":"","categories":[],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]}],"suppliedProducts":[],"partnershipProgramme":{"levels":[{"id":9,"level":"Registered"},{"id":33,"level":"Preferred"},{"id":34,"level":"Premier"},{"id":35,"level":"Distributor"}],"partnerDiscounts":{"Registered":"","Preferred":"","Premier":"","Distributor":""},"registeredDiscounts":{"Registered":"","Preferred":"","Premier":"","Distributor":""},"additionalBenefits":[],"salesPlan":{"Registered":"","Preferred":"","Premier":"","Distributor":""},"additionalRequirements":[]}}},"aliases":{},"links":{},"meta":{},"loading":false,"error":null},"implementations":{"implementationsByAlias":{},"aliases":{},"links":{},"meta":{},"loading":false,"error":null},"agreements":{"agreementById":{},"ids":{},"links":{},"meta":{},"loading":false,"error":null},"comparison":{"loading":false,"error":false,"templatesById":{},"comparisonByTemplateId":{},"products":[],"selectedTemplateId":null},"presentation":{"type":null,"company":{},"products":[],"partners":[],"formData":{},"dataLoading":false,"dataError":false,"loading":false,"error":false},"catalogsGlobal":{"subMenuItemTitle":""}}
