HP, IBM Make Virtual Motions: Page 2 of 3

Some of the customers who have deployed CASA include The Metropolitan Museum of Art; Energy United, a utility in North Carolina; San Juan Unified School District in California; and National Medical Health Card Systems Inc. (NMHC), a prescription drug management firm.

HP's next release of CASA, version 6, is due out in the fourth quarter of 2003. This version will be based around the 16-port Brocade Communications Systems Inc. (Nasdaq: BRCD) switch (which Brocade acquired via Rhapsody) and will incorporate elements of Compaq's VersaStor host-based virtualization technology (see HP Picks Rhapsody and Brocade Reupholsters Rhapsody).

Sorenson maintains that the Brocade/Rhapsody switch will simply augment the features provided by the current PC-based CASA. "All you do is get more scaleability and performance," he says. "The functionality is the same... it will be a seamless upgrade."

Meanwhile, IBM is getting ready to release its own block-level virtualization product -- dubbed the TotalStorage SAN Volume Controller -- the basic details of which Big Blue outlined about a year ago (see IBM Software Slides to 2003).

The in-band SAN Volume Controller, code-named Lodestone, is based on clustered IBM xSeries servers running Linux. According to IBM, additional nodes can be added nondisruptively to provide "enterprise-class scalability." But the first iteration of SAN Volume Controller, which is expected to ship sometime this summer, appears to have some serious limitations. For one thing, it will initially support only IBM Enterprise Storage Server (a.k.a. Shark) and FastT disk arrays.
