RAS Memory Features

Cisco UCS Manager expands on Intel® Xeon® processor support for RAS memory features via the BIOS. These features expand on the capabilities of the processor to increase the performance and reliability of memory DIMMs.

These include limiting presented memory to a subset of overall memory, ability to create a mirrored region in memory map with the attributes of a partial mirror copy, rather than the complete mirror copy.
