EMC Takes CDP Downmarket

With storage vendors struggling to squeeze additional revenues out of large enterprises, EMC has refocused on smaller firms, today unveiling scaled-down versions of its Clariion hardware and RecoverPoint software for backup, archiving, and CDP. (See Vendors Set Sights on SMB Windfall, EMC Delivers Insignia to SMBs, EMC Eyes SMB Push, and EMC Retrospect Supports Vista.)

RecoverPoint, which EMC acquired when it bought Kashya, supports continuous snapshots, typically seconds apart, as well as full CDP, albeit limited to SAN devices. (See EMC Coughs Up for Kashya.)

Last October, the vendor unveiled an enterprise version of the RecoverPoint software, capable of sharing data across its Clariion devices and SAN products from other vendors. Today, EMC took the wraps off an SMB version of the software, RecoverPoint SE, which only works across Clariion devices, and, at $10,000 per array, is significantly cheaper than the $83,000 enterprise version.

EMC execs refused to say when they are likely to extend this level of functionality to their Celerra NAS devices, although rival NetApp is also dragging its feet in this area. (See Exanet Dips Toe in CDP Pool.) NetApp acquired CDP technology when it bought Alacritus in 2005 but hasn't yet rolled out a full CDP product, although it does support snapshots on its NAS systems. (See NetApp Annexes Alacritus.)

The vendor did not respond to Byte and Switch's request for information on its CDP roadmap, although NetApp is said to be considering rolling out CDP on its VTLs. "We haven't seen [the Alacritus CDP technology] surface yet," says Dianne McAdam, director of enterprise infrastructure at analyst firm The Clipper Group, adding that a CDP/clustered NAS combo would be useful for users. "You're giving them more storage under the same management umbrella."
