Novell Monday announced it had signed a definitive agreement to acquire for $205 million PlateSpin, a maker of tools to help companies adopt, extend and manage server virtualization in the data center.

The deal, expected to close by April 30, will equip Novell with the technology to help customers better manage and optimize heterogeneous physical and virtual servers in next-generation data centers, the company said in a press conference call. PlateSpin, founded in 2003, generated more than $20 million in revenue in 2007 with its technology that disconnects software from hardware and allows servers to be streamed over a network from any source to any destination. Such capabilities, Novell executives say, will enable Novell to help its customers better manage workloads and optimize data-center resources in any environment. "It is a cornerstone of Novell corporate strategy to help our customers work in a mixed environment," said Ron Hovsepian, president and CEO of Novell.

The PlateSpin deal is Novell’s second in two weeks. Last week, Novell announced the acquisition of open source collaboration vendor SiteScape. Novell officials are undecided on whether they will make any of PlateSpin's technology open source.

The pending acquisition will allow PlateSpin to expand its reach into larger companies and couple its technology with Novell's ZENworks management tools to "become a powerhouse," says Stephen Pollack, founder and CEO of PlateSpin, which is headquartered in Toronto.

This acquisition ideally would help Novell accomplish a goal toward which many management and virtualization vendors are working: heterogeneous management of multivendor virtualization platforms. VMware last fall acquired Dunes Technologies to bring more management capabilities in-house, and Microsoft is expected to couple its virtualization wares with management capabilities.

"It's going to be a big year for virtualization, and there is an awful lot of money floating around the big players in the management market," such as BMC Software, CA, EMC, HP and IBM, says Rich Ptak, principal and founder of market research firm Ptak, Noel and Associates. "The demand for platform-agnostic, heterogeneous virtual management is going to be there, and Microsoft is going to put a lot of pressure on the virtualization market because it is beefing up its management capabilities. Successful vendors have to make virtualization accessible and make management a critical function that is easy to implement."
