Puppet Labs, a data center automation company, is announcing today that virtualization giant (and previous investor) VMware has invested $30 million in the company. This brings the company's total funding to $46 million. Puppet Labs' other investors include True Ventures, Cisco, Google Ventures, Kleiner Perkins Caufield & Byers, and Radar Partners. The company declined to reveal the valuation in the round, but we hear it was a "healthy increase" from the last round in 2011.
