Next-generation data protection and integrity When dealing with large-scale data storage, businesses require a solution that offers reliable backup and prevents file corruption. With support for the next-generation Btrfs file system, RackStation series Plus ensures information is stored with a high level of data integrity, while providing flexible and efficient data protection tools. Fast and efficient snapshots Snapshots preserve the history of a shared folder allowing you to save up to 2561 backup copies for point-in-time recovery. Snapshots can be automatically captured up to every 5 minutes, without noticeably impacting system performance. Metadata mirroring and survivability Btrfs file system stores two copies of critical metadata on a volume, improving the availability and ensuring the integrity of your file system. Corruption detection and correction Btrfs generates checksums for data and metadata, and then verifies the checksums during each read process to ensure the integrity of the filesystem and files. If the file system discovers a mismatch, metadata will be repaired to keep file system consistent. In the mean time, corrupted files will be reported and logged. Customizable quotas for shared folders With Btrfs, you can specify a storage limit for each shared folder, making it possible to precisely control space consumption when multiple teams or departments save files on the same Synology NAS server. Quad-core CPU for speedy performance RackStation series Plus is powered by a quad-core CPU running at 2.4 GHz. Combined with 2GB of DDR3 RAM (expandable to 6GB), it delivers blazing-fast performance over 450 MB/s reading and 380 MB/s writing2. This kind of power makes it easy for RackStation series Plus to run multiple applications and deliver consistently high throughput to all connected clients. On-the-fly scalability up to 24 drives As your data storage needs grow, RackStation series Plus can be connected to a dedicated RackStation series Plus expansion unit3, allowing you to expand storage capacity to 24 drives for a total of 192TB4 without disrupting service. The specially-designed connection cables ensure high-speed data transmission between the main server and expansion unit.
