EMC Refreshes NAS, SAN

EMC unveiled a few new software twists to challenge Network Appliances NAS products today as well as its expected upgrade of the Symmetrix DMX-3 high-end SAN system to take on Hitachi Data Systems and IBM. (See EMC Upgrades Symmetrix.)

On the NAS front, EMC added global namespace management to its Rainfinity file virtualization product and iSCSI file sharing and replication for its Celerra platform.

While iSCSI is usually thought of as a SAN protocol, EMC's new IP products are about improving its Celerra NAS rather than its iSCSI Clariion systems.

“We don't consider IP all about SANs. We’re looking at NAS, iSCSI, and Fibre Channel together,” EMC director of technology analysis Ken Steinhardt said in an interview following EMC's product rollout webcast from London. “Customers shouldn’t be hard-locked into one or another.”

That echoes the NetApp unified storage approach, which gives the customers the option of NAS, Fibre Channel, or iSCSI on all of its systems. EMC isn’t about to blur the lines of its Fibre Channel SAN and NAS platforms, but its Multi-Path File System for iSCSI (MPFSi) software will let customers move block and file storage in one system.
