StackIQ, a Solana Beach software maker specializing in products to manage large infrastructures, said that it received $6 million in series B funding.

Existing investors Anthem Venture Partners and Avalon Ventures contributed to the round, as well as new investors Grayhawk Capital, Keshif Ventures, DLA Piper and OurCrowd.

The company said it planned to use its new funds to scale its sales, marketing and operations to meet demand.

StackIQ was founded in 2006 and raised $5 million in a series A round in February 2011. Tim McIntire is CEO and co-founder. Longtime San Diego tech executive and investor Joe Markee is executive chairman of the board.

StackIQ’s foundation is something called Rocks — an open-source software for cluster management. StackIQ’s software incorporates code developed by the Rocks Cluster Group at the San Diego Supercomputer Center at University of California, San Diego.
