Virtualized desktops are generally hosted on a remote central server, rather than the hard drive of the personal computer. Because the client-server computing model is used in virtualizing desktops, desktop virtualization is also known as client virtualization.\r\nDesktop virtualization provides a way for users to maintain their individual desktops on a single, central server. The users may be connected to the central server through a LAN, WAN or over the Internet.\r\nDesktop virtualization has many benefits, including a lower total cost of ownership (TCO), increased security, reduced energy costs, reduced downtime and centralized management.\r\nLimitations of desktop virtualization include difficulty in maintenance and set up of printer drivers; increased downtime in case of network failures; complexity and costs involved in VDI deployment and security risks in the event of improper network management.<br /><br />","materialsDescription":" <span style=\"font-weight: bold; \">What are types of desktop virtualization technologies?</span>\r\nHost-based forms of desktop virtualization require that users view and interact with their virtual desktops over a network by using a remote display protocol. Because processing takes place in a data center, client devices can be traditional PCs, but also thin clients, zero clients, smartphones and tablets. Examples of host-based desktop virtualization technology include:\r\n<span style=\"font-weight: bold; \">Host-based virtual machines:</span> Each user connects to an individual VM that is hosted in a data center. The user may connect to the same VM every time, allowing for personalization (known as a persistent desktop), or be given a fresh VM at each login (a nonpersistent desktop).\r\n<span style=\"font-weight: bold; \">Shared hosted:</span> Users connect to a shared desktop that runs on a server. Microsoft Remote Desktop Services, formerly Terminal Services, takes this client-server approach. Users may also connect to individual applications running on a server; this technology is an example of application virtualization.\r\n<span style=\"font-weight: bold; \">Host-based physical machines:</span> The operating system runs directly on another device's physical hardware.\r\nClient virtualization requires processing to occur on local hardware; the use of thin clients, zero clients and mobile devices is not possible. These types of desktop virtualization include:\r\n<span style=\"font-weight: bold; \">OS image streaming:</span> The operating system runs on local hardware, but it boots to a remote disk image across the network. This is useful for groups of desktops that use the same disk image. OS image streaming, also known as remote desktop virtualization, requires a constant network connection in order to function.\r\n<span style=\"font-weight: bold; \">Client-based virtual machines:</span> A VM runs on a fully functional PC, with a hypervisor in place. Client-based virtual machines can be managed by regularly syncing the disk image with a server, but a constant network connection is not necessary in order for them to function.\r\n<span style=\"font-weight: bold;\">Desktop virtualization vs. virtual desktop infrastructure</span>\r\nThe terms <span style=\"font-style: italic;\">desktop virtualization</span> and virtual desktop infrastructure (VDI) are often used interchangeably, but they are not the same. While VDI is a type of desktop virtualization, not all desktop virtualization uses VDI.\r\nVDI refers to the use of host-based VMs to deliver virtual desktops, which emerged in 2006 as an alternative to Terminal Services and Citrix's client-server approach to desktop virtualization technology. Other types of desktop virtualization -- including the shared hosted model, host-based physical machines and all methods of client virtualization -- are not examples of VDI.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/icon_Desktop_virtualization.png","alias":"desktop-virtualization"}},"branches":"Information Technology","companyUrl":"http://gigatech.az/","countryCodes":["AZE"],"certifications":[],"isSeller":true,"isSupplier":true,"isVendor":false,"presenterCodeLng":"","seo":{"title":"GIGATECH","keywords":"computer, GIGATECH, equipment, retail, such, market, Baku, leader","description":"\r\n&quot;GIGATECH&quot; Computer shop was founded on 15 December 2003 and specializes in the sale of consumables for computer equipment.

Superdome is represented by three models with 16, 32 and 64 processor sockets. Within the family, there is the possibility of moving from younger models to older ones, which ensures a reduction in initial costs, investment protection and the possibility of a phased increase in system performance. Superdome is a universal hierarchical crossbar architecture specifically designed to work with various types of processors. The main components of the architecture are Cells, Crossbar Backplane, and I / O subsystems.<br />\r\nThe cell board is the main unit of the Superdome system. It is a symmetrical multiprocessor (SMP) containing 4 processor sockets and up to 64 GB of main memory. It is possible (but not necessary) to connect to the cell its own I / O subsystem, which is an I / O basket with 12 PCI-X slots. Each cell can work in different configurations, i.e., be connected to other cells or form an independent independent server. In one system, cell boards can be combined with both PA-RISC processors and Itanium processors.<br />\r\nBackplane patch panels provide a non-blocking connection between cells, their associated memory, and I / O modules. The main principle underlying Superdome is the balanced performance of the system at all levels of the hierarchy in order to exclude the appearance of additional delays when the processors of one cell access the RAM located on other cells. The developed architecture allows the system to demonstrate record performance indicators for various types of tasks, such as operational transaction processing, technical calculations, processing of Internet transactions, analysis of large volumes of data, etc.<br />\r\nA single Superdome system can be logically divided into many hardware independent, software independent partitions, virtual machines, or resource partitions within a single server. Each hardware / software partition or virtual machine is running its own independent operating system. For cells with PA-RISC processors, the operating system is HP-UX 11i, and for cells with Itanium processors, HP-UX, Linux, Microsoft Windows 2003, and OpenVMS.\r\nTo implement effective system management and technical support, the Superdome server family includes:\r\n<ul><li>Event Monitoring System (EMS), an alert service that monitors the status of server hardware, including processors, memory, FC components, system buses, cache, system temperature, battery status, fans, power supplies.</li></ul>\r\n<ul><li>A hardware inventory service in Support Tools Manager (STM) that provides system inventory information, including serial numbers, part numbers, version levels, and so on.</li></ul>\r\n<ul><li>Support Management Station (SMS), which is used to start the process of scanning, diagnostics and testing the platform throughout the life cycle, including upgrades.</li></ul>\r\nThe Superdome family provides customers with investment protection and uptime thanks to a system infrastructure designed to upgrade to next-generation processors.","shortDescription":"HP Superdome is a premium server designed and manufactured by Hewlett Packard Enterprise.","type":null,"isRoiCalculatorAvaliable":false,"isConfiguratorAvaliable":false,"bonus":100,"usingCount":19,"sellingCount":13,"discontinued":0,"rebateForPoc":0,"rebate":0,"seo":{"title":"HP Integrity Superdome","keywords":"","description":"HP Superdome is the family of enterprise-class high-performance servers manufactured with both the PA-8900 processors (HP 9000 family) and Intel Itanium 2 processors (HP Integrity family).

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 &quot;services&quot;, 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 &quot;server-class hardware&quot; 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 &quot;servers serve users&quot; (and &quot;users use servers&quot;), in the sense of &quot;obey&quot;, today one often says that &quot;servers serve data&quot;, in the same sense as &quot;give&quot;. For instance, web servers &quot;serve web pages to users&quot; or &quot;service their requests&quot;.\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 &quot;server&quot; 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 &quot;computerhope.com&quot;), 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.

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 &quot;services&quot;, 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 &quot;server-class hardware&quot; 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 &quot;servers serve users&quot; (and &quot;users use servers&quot;), in the sense of &quot;obey&quot;, today one often says that &quot;servers serve data&quot;, in the same sense as &quot;give&quot;. For instance, web servers &quot;serve web pages to users&quot; or &quot;service their requests&quot;.\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.

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 &quot;network blindness.&quot; 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.

Because the client-server computing model is used in virtualizing desktops, desktop virtualization is also known as client virtualization.\r\nDesktop virtualization provides a way for users to maintain their individual desktops on a single, central server. The users may be connected to the central server through a LAN, WAN or over the Internet.\r\nDesktop virtualization has many benefits, including a lower total cost of ownership (TCO), increased security, reduced energy costs, reduced downtime and centralized management.\r\nLimitations of desktop virtualization include difficulty in maintenance and set up of printer drivers; increased downtime in case of network failures; complexity and costs involved in VDI deployment and security risks in the event of improper network management.<br /><br />","materialsDescription":" <span style=\"font-weight: bold; \">What are types of desktop virtualization technologies?</span>\r\nHost-based forms of desktop virtualization require that users view and interact with their virtual desktops over a network by using a remote display protocol. Because processing takes place in a data center, client devices can be traditional PCs, but also thin clients, zero clients, smartphones and tablets. Examples of host-based desktop virtualization technology include:\r\n<span style=\"font-weight: bold; \">Host-based virtual machines:</span> Each user connects to an individual VM that is hosted in a data center. The user may connect to the same VM every time, allowing for personalization (known as a persistent desktop), or be given a fresh VM at each login (a nonpersistent desktop).\r\n<span style=\"font-weight: bold; \">Shared hosted:</span> Users connect to a shared desktop that runs on a server. Microsoft Remote Desktop Services, formerly Terminal Services, takes this client-server approach. Users may also connect to individual applications running on a server; this technology is an example of application virtualization.\r\n<span style=\"font-weight: bold; \">Host-based physical machines:</span> The operating system runs directly on another device's physical hardware.\r\nClient virtualization requires processing to occur on local hardware; the use of thin clients, zero clients and mobile devices is not possible.

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 &quot;chunk&quot; 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.

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 &quot;firmware&quot;), 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 &quot;deleted&quot; 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 &quot;data recovery&quot; 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 &quot;back up&quot; (a phrasal verb), whereas the noun and adjective form is &quot;backup&quot;.\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"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},{"id":47,"logoURL":"https://old.roi4cio.com/fileadmin/content/ProLiant_DL_Rack.png","logo":true,"scheme":false,"title":"HPE ProLiant DL Rack","vendorVerified":0,"rating":"2.00","implementationsCount":1,"suppliersCount":0,"supplierPartnersCount":451,"alias":"hpe-proliant-dl-rack","companyTitle":"Hewlett Packard Enterprise","companyTypes":["supplier","vendor"],"companyId":172,"companyAlias":"hewlett-packard-enterprise","description":"The DL family of servers are the most flexible, reliable, and performance-optimized ProLiant rack servers—ever.

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. &quot;U&quot; 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 &quot;low-profile&quot; 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. 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"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},{"id":48,"logoURL":"https://old.roi4cio.com/fileadmin/content/HPE_3PAR_StoreServ.png","logo":true,"scheme":false,"title":"HPE 3PAR StoreServ","vendorVerified":0,"rating":"2.00","implementationsCount":3,"suppliersCount":0,"supplierPartnersCount":451,"alias":"hpe-3par-storeserv","companyTitle":"Hewlett Packard Enterprise","companyTypes":["supplier","vendor"],"companyId":172,"companyAlias":"hewlett-packard-enterprise","description":"<span style=\"background-color: rgb(252, 252, 252); color: rgb(51, 51, 51); font-family: &quot;Metric Light&quot;, Arial, sans-serif; font-size: 18px; \">HPE 3PAR StoreServ Storage is a new class of enterprise flash arrays with greater than 3M IOPS, sub-millisecond latencies, a 6x density advantage, and scalability of over 20 PiB of usable capacity for massive consolidation.&nbsp;</span>","shortDescription":"HPE 3PAR StoreServ Scalable to Meet Growing Enterprise Requirements.","type":null,"isRoiCalculatorAvaliable":false,"isConfiguratorAvaliable":false,"bonus":100,"usingCount":6,"sellingCount":12,"discontinued":0,"rebateForPoc":0,"rebate":0,"seo":{"title":"HPE 3PAR StoreServ","keywords":"StoreServ, 3PAR, scalability, advantage, over, density, usable, massive","description":"<span style=\"background-color: rgb(252, 252, 252); color: rgb(51, 51, 51); font-family: &quot;Metric Light&quot;, Arial, sans-serif; font-size: 18px; \">HPE 3PAR StoreServ Storage is a new class of enterprise flash arrays with greater than 3M IOPS, sub-millisec","og:title":"HPE 3PAR StoreServ","og:description":"<span style=\"background-color: rgb(252, 252, 252); color: rgb(51, 51, 51); font-family: &quot;Metric Light&quot;, Arial, sans-serif; font-size: 18px; \">HPE 3PAR StoreServ Storage is a new class of enterprise flash arrays with greater than 3M IOPS, sub-millisec","og:image":"https://old.roi4cio.com/fileadmin/content/HPE_3PAR_StoreServ.png"},"eventUrl":"","translationId":103,"dealDetails":null,"roi":null,"price":null,"bonusForReference":null,"templateData":[],"testingArea":"","categories":[{"id":501,"title":"All-flash and Hybrid Storage","alias":"all-flash-and-hybrid-storage","description":" Costs have come down making hybrid and all-flash enterprise storage solutions the preferred choice for storing, processing and moving the massive volumes of business data generated in today’s cloud, mobile and IoT environment.\r\nll-flash storage arrays utilize solid-state drives (SSDs) to deliver high-performance and low-latency workloads using data compression and deduplication technologies.

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 &quot;services&quot;, 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 &quot;server-class hardware&quot; 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 &quot;servers serve users&quot; (and &quot;users use servers&quot;), in the sense of &quot;obey&quot;, today one often says that &quot;servers serve data&quot;, in the same sense as &quot;give&quot;. For instance, web servers &quot;serve web pages to users&quot; or &quot;service their requests&quot;.\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 &quot;server&quot; 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 &quot;computerhope.com&quot;), 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.

Routers perform the traffic directing functions on the Internet. Data sent through the internet, such as a web page or email, is in the form of data packets. A packet is typically forwarded from one router to another router through the networks that constitute an internetwork (e.g. the Internet) until it reaches its destination node.\r\nA router is connected to two or more data lines from different IP networks. When a data packet comes in on one of the lines, the router reads the network address information in the packet header to determine the ultimate destination. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey.\r\nThe most familiar type of IP routers are home and small office routers that simply forward IP packets between the home computers and the Internet. An example of a router would be the owner's cable or DSL router, which connects to the Internet through an Internet service provider (ISP). More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone.\r\nThe main purpose of a router is to connect multiple networks and forward packets destined either for its own networks or other networks. A router is considered a layer-3 device because its primary forwarding decision is based on the information in the layer-3 IP packet, specifically the destination IP address. When a router receives a packet, it searches its routing table to find the best match between the destination IP address of the packet and one of the addresses in the routing table. Once a match is found, the packet is encapsulated in the layer-2 data link frame for the outgoing interface indicated in the table entry. A router typically does not look into the packet payload,[citation needed] but only at the layer-3 addresses to make a forwarding decision, plus optionally other information in the header for hints on, for example, quality of service (QoS). For pure IP forwarding, a router is designed to minimize the state information associated with individual packets. Once a packet is forwarded, the router does not retain any historical information about the packet.\r\nThe routing table itself can contain information derived from a variety of sources, such as a default or static routes that are configured manually, or dynamic routing protocols where the router learns routes from other routers. A default route is one that is used to route all traffic whose destination does not otherwise appear in the routing table; this is common – even necessary – in small networks, such as a home or small business where the default route simply sends all non-local traffic to the Internet service provider. The default route can be manually configured (as a static route), or learned by dynamic routing protocols, or be obtained by DHCP.\r\nA router can run more than one routing protocol at a time, particularly if it serves as an autonomous system border router between parts of a network that run different routing protocols; if it does so, then redistribution may be used (usually selectively) to share information between the different protocols running on the same router.\r\nBesides making a decision as to which interface a packet is forwarded to, which is handled primarily via the routing table, a router also has to manage congestion when packets arrive at a rate higher than the router can process. Three policies commonly used in the Internet are tail drop, random early detection (RED), and weighted random early detection (WRED). Tail drop is the simplest and most easily implemented; the router simply drops new incoming packets once the length of the queue exceeds the size of the buffers in the router. RED probabilistically drops datagrams early when the queue exceeds a pre-configured portion of the buffer, until a pre-determined max, when it becomes tail drop. WRED requires a weight on the average queue size to act upon when the traffic is about to exceed the pre-configured size, so that short bursts will not trigger random drops.\r\nAnother function a router performs is to decide which packet should be processed first when multiple queues exist. This is managed through QoS, which is critical when Voice over IP is deployed, so as not to introduce excessive latency.\r\nYet another function a router performs is called policy-based routing where special rules are constructed to override the rules derived from the routing table when a packet forwarding decision is made.\r\nRouter functions may be performed through the same internal paths that the packets travel inside the router. Some of the functions may be performed through an application-specific integrated circuit (ASIC) to avoid overhead of scheduling CPU time to process the packets. Others may have to be performed through the CPU as these packets need special attention that cannot be handled by an ASIC.","materialsDescription":" <span style=\"font-weight: bold;\">What Is a Router?</span>\r\nRouters are the nodes that make up a computer network like the internet. The router you use at home is the central node of your home network.\r\nIt functions as an information manager between the internet and all devices that go online (i.e. all devices connected to the router). Generally speaking, routers direct incoming traffic to its destination.\r\nThis also makes your router the first line of security in protecting your home network from malicious online attacks.\r\n<span style=\"font-weight: bold;\">What Does a Router Do?</span>\r\nYour router handles network traffic. For example, to view this article, data packages coding for this website have to transit from our server, through various nodes on the internet, and finally through your router to arrive on your phone or computer. On your device, your browser decodes those data packages to display the article you’re currently reading.\r\nSince a typical household has more than one device that connects to the internet, you need a router to manage the incoming network signals. In other words, your router makes sure that the data packages coding for a website you want to view on your computer aren’t sent to your phone. It does that by using your device’s MAC address.\r\nWhile your router has a unique (external) IP address to receive data packages from servers worldwide, every device on your home network also carries a unique MAC address. Simply put, when you try to access information online, your router maintains a table to keep track of which device requested information from where. Based on this table, your router distributes incoming data packages to the correct recipient.\r\n<span style=\"font-weight: bold;\">What Is the Difference Between Modems and Routers?</span>\r\nA modem turns the proprietary network signal of your ISP (internet service provider) into a standard network signal. In theory, you can choose between multiple ISPs and some of them may use the same delivery route. Your modem knows which signals to read and translate.\r\nThe kind of modem your ISP will provide you with depends on how you’re connecting to the internet. For example, a DSL modem requires a different technology than a cable or fiber optic broadband modem. That’s because one uses the copper wiring of your telephone line, while the others use a coaxial or a fiber optic cable, respectively.\r\nThe DSL modem has to filter and read both the low frequencies that phone and voice data produce, as well as the high frequencies of internet data. Cable modems, on the other hand, have to differentiate between television and internet signals, which are transmitted on different channels, rather than different frequencies. Finally, fiber optic uses pulses of light to transmit information. The modem has to decode these signals into standard data packages.\r\nOnce the modem has turned the ISP’s network signal into data packages, the router can distribute them to the target device.","iconURL":"https://old.roi4cio.com/fileadmin/user_upload/Router1.png"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},{"id":384,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/Server_HPE_ProLiant_DL360_Gen9.png","logo":true,"scheme":false,"title":"HPE ProLiant DL360 Gen9 Server","vendorVerified":0,"rating":"2.00","implementationsCount":2,"suppliersCount":0,"supplierPartnersCount":451,"alias":"hpe-proliant-dl360-gen9-server","companyTitle":"Hewlett Packard Enterprise","companyTypes":["supplier","vendor"],"companyId":172,"companyAlias":"hewlett-packard-enterprise","description":"Does your data center need a performance driven dense 1U server that you can confidently deploy for virtualization, data base, or high-performance computing?

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. &quot;U&quot; 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 &quot;low-profile&quot; 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. 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.

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 &quot;chunk&quot; 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"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},{"id":421,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/HP_ProLiant_BL_bleid-servery.png","logo":true,"scheme":false,"title":"HPE ProLiant BL Server Blade","vendorVerified":0,"rating":"2.00","implementationsCount":10,"suppliersCount":0,"supplierPartnersCount":451,"alias":"hpe-proliant-bl-server-blade","companyTitle":"Hewlett Packard Enterprise","companyTypes":["supplier","vendor"],"companyId":172,"companyAlias":"hewlett-packard-enterprise","description":"HPE ProLiant BL Server Blade allow you to choose the type of connection and storage.\r\n<span style=\"font-weight: bold; \">Benefits:</span>\r\n- HPE ProLiant BL Server Blade are compact and optimized for rapid deployment and changing of server roles;\r\n- The ideal solution for enterprises and service providers with limited space.\r\n","shortDescription":"HPE ProLiant BL Server Blade with the latest dual-core processors have the same features, capabilities and benefits of rack servers, consuming less energy and are more efficient to use.","type":null,"isRoiCalculatorAvaliable":false,"isConfiguratorAvaliable":false,"bonus":100,"usingCount":12,"sellingCount":0,"discontinued":0,"rebateForPoc":0,"rebate":0,"seo":{"title":"HPE ProLiant BL Server Blade","keywords":"Blade, ProLiant, Server, ideal, roles, server, changing, solution","description":"HPE ProLiant BL Server Blade allow you to choose the type of connection and storage.\r\n<span style=\"font-weight: bold; \">Benefits:</span>\r\n- HPE ProLiant BL Server Blade are compact and optimized for rapid deployment and changing of server roles;\r\n- The ideal s","og:title":"HPE ProLiant BL Server Blade","og:description":"HPE ProLiant BL Server Blade allow you to choose the type of connection and storage.\r\n<span style=\"font-weight: bold; \">Benefits:</span>\r\n- HPE ProLiant BL Server Blade are compact and optimized for rapid deployment and changing of server roles;\r\n- The ideal s","og:image":"https://old.roi4cio.com/fileadmin/user_upload/HP_ProLiant_BL_bleid-servery.png"},"eventUrl":"","translationId":422,"dealDetails":null,"roi":null,"price":null,"bonusForReference":null,"templateData":[],"testingArea":"","categories":[{"id":435,"title":"Rack Server","alias":"rack-server","description":"A rack mount server is a great way to maximize your shelf space by packing a lot of servers into a small space. 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. &quot;U&quot; 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 &quot;low-profile&quot; 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. 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"}],"characteristics":[],"concurentProducts":[],"jobRoles":[],"organizationalFeatures":[],"complementaryCategories":[],"solutions":[],"materials":[],"useCases":[],"best_practices":[],"values":[],"implementations":[]},{"id":409,"logoURL":"https://old.roi4cio.com/fileadmin/user_upload/HPE_logo.jpeg","logo":true,"scheme":false,"title":"HPE Intelligent Management Center (IMC)","vendorVerified":0,"rating":"2.40","implementationsCount":1,"suppliersCount":0,"supplierPartnersCount":451,"alias":"hpe-intelligent-management-center-imc","companyTitle":"Hewlett Packard Enterprise","companyTypes":["supplier","vendor"],"companyId":172,"companyAlias":"hewlett-packard-enterprise","description":"Network managers, engineers, and operators face complex challenges in their mission to deliver a reliable\r\nand available network infrastructure.

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&nbsp; 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":[]}],"partnershipProgramme":null}},"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":""}}
