In a long-expected move, Network Appliance has added block-level de-duplication to its FAS and NearStore R200 product lines. The vendor's Advanced Single Instance Storage (A-SIS) is now offered as a free upgrade to Ontap 7G customers with maintenance contracts; others will pay a "nominal" fee of roughly 1 to 2 percent of the overall cost of their system.
Up to now, NetApp offered A-SIS only in systems bundled with Symantec NetBackup as part of a joint solution.
NetApp's NearStore VTL, which runs under a different operating system, will get its own de-duplication software in mid-June. That announcement is scheduled for the Symantec Vision event in Las Vegas.
The Ontap GX operating system is earmarked to get de-duplication too, but no date's been set. NetApp believes the help with de-dupe is needed primarily in mainstream enterprise applications that use Ontap 7G.
NetApp has tarried in delivering this feature, for which the vendor claims over 50 early adopters. Competitors include Asigra, Quantum, Sepaton, and Symantec, which also support de-duplication of data after it's written to a target disk. Data Domain, Diligent, and EMC (via its Avamar acquisition) de-dupe prior to backup. (See De-Dupe Deep Dive.)
