Open CloudServer

A chassis system that utilizes EIA 310-D 19" racks has been contributed by Microsoft. The system has been built with operational knowledge gained by operating over a million servers. The 12U chassis has dedicated, hard-wired out of band management, phase-balanced power, and high efficiency cooling. All of these are accepted by IC

System on Chip (SoC) Servers

The SoC systems are typically a server card that must be installed into a larger platform to operate. These cards could be installed onto a larger "baseboard" with many SoC cards or as a single server into a larger platform. There are storage solutions that utilize a single Micro-Server card.

This section includes the SoC cards and applicable platforms.
