Calxeda says its 64-bit processors based on the ARMv8-A architecture will be available for tests in the first half of 2014, and servers built around the low-power chips will become available in the second half. "64-bit is coming. It will be an amazing change in the [server] industry," Calxeda's Karl Freund says. "Our priority is to get them to market as fast as possible." Separately, Dell is set to demonstrate a low-power ARM-based microserver with the Fedora Linux operating system at ARM's TechCon conference.
