Infinio (née SilverLining Systems), a not yet two-year-old Cambridge start-up developing software to improve data storage performance in virtual environments, said Tuesday that it's raised a $10 million Series A round led by new investors Highland Capital Partners and Bessemer Venture Partners.

Both get a seat on the board.

That gives Infinio $12 million since it was started. Earlier investors were also part of the Series A, including Lightspeed Venture Partners, Founder Collective, the New York City Seed Fund and some angel backers.

Infinio reckons storage performance issues are "the most expensive bottleneck in virtual environments."

"The majority of performance problems in virtual environments are storage-related," Arun Agarwal, Infinio CEO, said in a statement. "Storage systems represent a huge portion of IT budgets, and too often, data center managers find themselves buying more hardware in an effort to improve performance, even when they have plenty of storage space. We're building a software product that will help solve that problem."

The widgetry won't beta for some months yet.

The company's looking for people and will be putting a marketing campaign together.
