IBM Announces Mid-Range Deduplication Appliance

By Computerworld Thu, Jul 29, 2010

IBM unveiled a new mid-range deduplication appliance and the company also announced enhancements, including a new policy engine, to its enterprise-class network-attached storage (NAS) array.

The new mid-range 2U high (3.5-in) ProtecTIER TS7610 is a gateway device, meaning, it sits between an application server and its primary storage array, such as the IBM XIV storage system .

The deduplication technology comes from IBM's acquisition of Diligent Technologies Corp. in 2008. In the fall of that year, IBM brought out the first ProtecTIER product based on Diligent technology.

And earlier this year, IBM released the ProtecTIER TS7680 gateway device for mainframes.

The low-end model can scale from 27TB of capacity using 60 15,000-rpm serial-attached SCSI disk drives with 450GB each. A base model can start at 60TB using 1TB Serial ATA drives and scale up to 7,200 drives and 14 petabytes.

The new SONAS policy engine allows system administrators to set up business policies for placing data on tiers of disk. The policies are based on how often it is used. The policy engine can also be set up to migrate data to tape archive systems or to delete it after a set time period.

IBM is also offering 600GB capacity serial SCSI (SAS) drives in the array, which offer 25% more capacity than its previous 450GB drives.

IBM is also now selling its SONAS NAS system as a gateway device for its XIV storage array, enabling both NAS and SAN traffic. Perspective users can order the new SONAS NAS configurations today. IBM expects to begin shipping them Aug. 13.
