Existing investors Battery Ventures, Flybridge Capital Partners and Highland Capital Partners also took part in the round.
Calxeda co-founder and CEO Barry Evans said, “Businesses require a more efficient solution for the web, cloud, and big data.
“That is what Calxeda is now delivering and this funding will enable us to go bigger and faster.”
The company says its hardware can deliver a ten-fold improvement in energy efficiency compared to regular x86 architecture servers.
Austin Ventures partner Clark Jernigan said, “In the time since we first met Calxeda, they have executed exceptionally well, and the market has begun to embrace disruptively power-efficient datacenter architectures.
“Calxeda has also demonstrated solid customer traction across several key end user segments, and we are very excited to join their already impressive investor group.”
Vulcan Capital managing director Steve Hall said, “I am very impressed with the innovative approach and completeness of Calxeda’s vision.
“Calxeda thinks like a solution company, aligning their technology to solve the bigger challenges. They aren’t just chip guys.”
In August big data developer sqrrl received seed funding from early stage investor Atlas Venture and venture capital firm Matrix Partners.
The company said the financing would enable it to “aggressively hire” to meet the rising demand for its products and fuel the release of an enterprise version of Apache Accumulo that extends the core technology.
