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.
