Designed for workgroups, departments, or remote offices requiring large amounts of storage and mobile/remote access requirements, the 20TB (4 x 5TB) 4-Bay SnapServer XSR 40 NAS from Overland Storage offers enterprise class data management and data protection features in a 1U rackmount form factor. With support for < 100 concurrent users and data performance speeds up to 40 MB/s, the XSR 40 runs on GuardianOS. This NAS comes pre-configured with 20TB (4 x 5TB) of storage and supports 4 x SATA II 3 Gb/s drive bays. It is powered by a 1.8 GHz processor and its 2GB of ECC RAM, which can be upgraded to 4GB, allows frequently-used files to be quickly accessed. Network connectivity is achieved using the dual Gigabit Ethernet ports. This NAS also has 2 x USB 2.0 ports for connecting external devices, such as an RDX QuickStor.
SnapServer's GuardianOS includes DynamicRAID for seamless storage expansion by adding or replacing hard drives as capacity requirements change. In addition, all SnapServer storage volumes can grow or shrink dynamically within the storage pool without IT intervention, helping to prevent provisioning errors and costly upgrades. Supported RAID modes include RAID 0, 1, 5, 6, 10, and JBOD, as well as Dynamic RAID Dual or Single Parity.
With both block and file level access, the XSR 40 has cross-platform compatibility with Windows, Linux, UNIX, and Macintosh systems. GuardianOS also includes additional data protection features such as high performance snapshots, direct backup to RDX, disk, or LTO tape, as well as BitTorrent Sync, which will help sync and replicate to other SnapServers in the event of disaster recovery. BitTorrent Sync will also enable anywhere file access with virtually any mobile device and optional data replication is also available.
The capacity of the XSR 40 can also be expanded. Although this NAS only comes pre-configured with 20TB of storage, drives can be added to the array, provided there are available drive bays, but further expansion is possible using the external 2U, 12-bay SnapExpansion chassis. Up to three SnapExpansion chassis units may be simultaneously utilized. The XSR 40 is compatible with Enterprise SATA II drives with capacities of 1, 2, 3, 4, 5, and 6TB.
The 20TB (4 x 5TB) 4-Bay SnapServer XSR 40 NAS has a power rating of 200W and operates on 100-240 VAC at 50-60 Hz. It has a maximum input current of 4A at 115 VAC and 2A at 230 VAC. It consumes 80W and includes a US power cord, an EMEA power cord, a UK power cord, a Serial DB9 to RJ-11 adapter, a fixed rack rail mounting kit, and 2 x 7.00' / 2.13m Cat-5 Ethernet cables.
