StackIQ, a startup that specializes in automating and managing big data clusters, has taken in a $6 million series B funding round. Grayhawk Capital, Keshif Ventures, DLA Piper and OurCrowd were new investors in this funding round alongside Anthem Venture Partners and Avalon Ventures. The cluster management space has seen some action in recent months. Bright Computing, which sells hardware-agnostic Linux cluster management software, took in $14.5 million in June. In August, Google partnered up with Mesosphere to allow Google Compute Engine users to easily spin up self-managing clusters.
