Calxeda, which is developing low-power server technology based on ARM processors, has raised an additional $55 million in funding.

 

ARM server specialist Calxeda has announced a $55 million round of additional funding led by Austin Ventures and Vulcan Capital, with participation by the firm’s existing investors. Calxeda says it will use the funding to accelerate its quest to bring the low-power computing seen in popular mobile devices to the web server market. The company’s processors  are based on technology from ARM Holdings, which has long been used in the iPhone and iPad.

 

Calxeda, which is based in Austin, recently told Data Center Knowledge that it expects server vendors to launch the first production-ready servers based on its technology by year-end. At least seven server vendors are working with Calxeda technology, including Boston Limited and HP.

“This significant infusion of capital will accelerate the exciting trajectory we’ve been on for the past four years,” said Calxeda co-founder and CEO Barry Evans. “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.”

Calxeda’s EnergyCore is based on processor technology from ARM and consumes about 5 watts of power – and as little as 1.5 watts in microserver configurations – which could allow data center operators to dramatically slash their power usage for some applications.

In announcing its new funding, Calxeda also alluded to performance testing and power measurements showing that Calxeda delivers “as much as a ten-fold improvement in energy efficiency compared to today’s commodity X86-based servers.” The company has not yet provided detailed results to document that claim. But its progress has generated  enthusiasm with its investors.

“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,” said Clark Jernigan, Venture Partner, Austin Ventures. “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.”
