Tandberg Data recently launched the DPS2000 NAS series of disk-based storage appliance for small to medium-sized businesses. Though named an NAS appliance, the DPS2000 is in fact the first unified NAS and SAN device release by the company, thanks to its support for iSCSI.
Available as a four-bay storage box with a capacity 4TB or in 1U rackmount configuration with either 4TB or 8TB of storage, the DPS2000 NAS is designed with hot-swap to complement its RAID capabilities. Where external connectivity is concerned, the storage server comes with 3 USB 2.0 ports and gigabit Ethernet, which is relatively standard hardware.
The device does come with a couple of features typically found only in higher-end appliances, such as hot-swappable power supplies and the ability to automatically rebuild hard-disk images in the background. This allows for zero downtime as burned-out power supplies or failed hard-disk drives can be changed as the DPS2000 continues to operate without interruption.
Under the hood, Linux software provides concurrent iSCSI block access together with CIFS, NFS and AFP capabilities. Tandberg says simultaneous access via file sharing and iSCSI to the same appliance is possible, which makes the DPS2000 NAS a very attractive proposition to SMBs.
For example, SMBs can leverage the NAS capabilities of the appliance to serve as a general file storage device for a small network, while also using it as a quick means to expand the storage capacities of local servers. As many as eight unique iSCSI targets can be maintained simultaneously by the DPS2000 NAS.
In addition, the DPS2000 also features block-level remote replication, which can be used to provide offsite storage to another DPS2000 to achieve high data availability and fast disaster recovery. A virtual appliance stacking feature also means that multiple DPS2000 NAS units can be stacked together to scale capacity as necessary.
Finally, Tandberg's AccuGuard backup and recovery software will be bundled together with the DPS2000 NAS. AccuGuard supports source-based deduplication, which does deduplication of data by identifying and removing redundant data prior to storing it.
According to the official press release, a 4TB version of the DPS2000 NAS with AccuGuard has a MSRP of $2,290. Price includes one year of onsite hardware service, where available.
