NetApp Extends De-Dupe to Rivals' Storage

Software upgrade turns vendor's V-Series controller into a de-dupe gateway for other vendors' arrays

NetApp, which like Sepaton, and Exagrid, uses a ‘post-processing’ approach, where data is de-duped after it is written to a target disk, has been ramping up its de-dupe strategy during recent months. Earlier this year, for example, the vendor was the first to extend its de-dupe capabilities from secondary to primary storage devices.

The vendor is touting today’s announcement as another plank in this primary de-dupe strategy.

”It’s for both primary and secondary storage, although the main use case is front-end primary” storage, says the NetApp exec. “HP, Diligent, all those folks, are talking the backup game, but the game has changed and it’s now on primary storage.”

Like NetApp’s V-Series, rival vendor Data Domain also offers de-dupe gateway devices that can be connected to storage from other vendors, although these focus on backup. Data Domain, unlike NetApp, uses “inline” de-duplication where data is compressed on the fly while it is being sent to the target.

Despite all of NetApp’s de-dupe hype, the vendor was unable to offer up any early adopters who are using the V-Series software upgrade, although Cummings reiterated that vendor’s commitment to de-dupe technology.
