The Series 2 financing, announced today, was led by vSpring Capital, with input from San Francisco Equity Partners, Weber Capital, and Convergence Partners. It brings Penguin's total funding to roughly $34 million since its founding in 1998.
The money will go largely to ongoing development and marketing of Scyld Clusterware, the software Penguin acquired with the 2003 purchase of Scyld Computing. Pesatori (ex-BlueArc) says enhancements will include scaleability, added support for specific vertical market customers, and other features. (See Ex-BlueArc Exec Joins Penguin.)
Scyld and clustering will take precedence over the Linux servers on which Penguin established its business. "Linux HPC or our main focus... and the sweet spot in the market is small clusters," Pesatori says. "That's the fastest-growing segment."
