VMware and NGDC

One audience member who was keen on the Storage VMotion was Kyle Meyer, a senior systems engineer at Johnson Controls, which has 350 to 400 VMware-powered virtual machines out of a collection of 2,300 total servers. Currently, when the company's EMC Clariion storage systems go off lease, the company has to shut down servers to switch to new storage systems — a task they typically schedule at 3am on Saturday in an effort to minimise disruption.

"Nondisruption is the biggest thing," Meyer said. " [Today] we lease Clariion. If we're moving it to somebody else, we've got to shut it down."

There are complications to using Storage VMotion, Rosenblum said in an interview after the speech. For one thing, moving a data store takes a long time, even with the "teeny" one and the high-speed network in the demo. For another, a database that's already running full-tilt might not have network capacity to spare for being moved to another storage system.

GlassHouse Technologies Inc. on Tuesday registered to raise as much as $100 million in an initial public offering that, despite the company's financial losses, could prove a hit with investors drawn to its focus on "virtualization" technology. The Framingham, Mass., company offers consulting services for companies that use virtualization software to improve the performance of corporate servers and cut costs in their data centers. GlassHouse also provides Internet-based data storage. "Software-as-a-service," or SaaS, companies and vendors of virtualization products have proved popular among investors in recent years as corporate customers seek alternatives to conventional packaged software. GlassHouse, with roots in both sectors, will test the strength of that interest, said Peter Falvey, managing director with Boston investment bank Revolution Partners. "It will be a bit of a bell weather," he says. "It's not as though it's the 15th SaaS m...
