Chip startup Calxeda raises $55 million for ARM-based servers

Calxeda, the startup that's building data centers with chips normally found in cell phones, has raised an additional $55 million, signaling that its low-power server technology may be gaining traction.

The company, which was founded four years ago by former Intel and Marvell engineer Barry Evans, is an early proponent of using ARM architecture in servers rather than traditional x86 designs popularized by Intel and Advanced Micro Devices.

"This significant infusion of capital will accelerate the exciting trajectory we've been on for the past four years," Evans said in a statement. "Businesses require a more … Read more

Powered by ARM chip, Calxeda server sips 5 watts

Start-up Calxeda is making an end run around the limitations of power in data centers by using chips normally used for mobile phones.

The company today is launching its EnergyCore "server on a chip" around the ARM processor, which yields a four-core server that runs at 5 watts and less than half a watt when idle. Hewlett-Packard plans to build a line of energy-efficient servers around EnergyCore.

The EnergyCore processing unit is well suited for "big data" applications that crunch large amounts of data in parallel, such as analytics, media streaming, or in-memory databases, according to … Read more
