SANs Encompass iSCSI

5:30 PM -- Among the slew of product rollouts EMC will make next week is one that reinforces the fact that Fibre Channel SAN vendors are increasingly learning to live with -- if not love -- iSCSI.

With its launch of Clariions that support iSCSI and Fibre Channel in the same system Monday, EMC will become the third FC SAN vendor to add an iSCSI product to its portfolio within a week. (See EMC in Full Launch Mode.) And that doesnt include IP SAN vendor LeftHand's announcement that it would make its SAN/IQ software available to install on Hewlett-Packard DL380 servers -- turning them into iSCSI controllers.

Earlier this week, Xiotech launched its entry-level IP SAN, the Magnitude 750. (See Xiotech Intros Storage System.) Pillar Data began offering iSCSI as an option with Fibre Channel on a new low-end Axiom system. (See Pillar Extends Reach.)

Outside of Pillar, all the other SAN vendors with recent iSCSI announcements had some type of IP SAN before. EMC sells low-end IP SANs, HP offers iSCSI for its midrange EVA SANs through a QLogic multiprotocol router (EMC uses a card version of QLogic's same product for its new Clariion), and Xiotech had iSCSI connectivity for its midrange Magnitudes.

Considering Fibre Channel vendors accepted iSCSI slowly and in small doses at first, we can assume they're adding more IP connectivity because they're getting more requests from customers.
