| Calxeda provides revolutionary efficiency to the data center. Leveraging ultra-low power technology from ARM, servers built on Calxeda’s silicon and software platform consume a fraction of the power and space of today’s best-in-class servers, enabling data centers to realize significant reduction in capital and operating expenses. The Calxedaplatform scales efficiently to thousands of server nodes, with unique network and storage acceleration, and is enhanced with management technology to deliver true “energy-proportional” computing. The result is a stunning breakthrough in performance efficiency, density, and scalability. | $55M / Series C / Oct 09, 2012 | ||
