Issue Description

Customer need to use all the DDR memory from server.

Handling Process

RH8100 V3 support functions Memory Mirroring and Memory Migration.



The Memory Mirroring function is used for mirroring a part of system memory and saving important data (this must be supported by the operating system). The minimum granularity is at HA level, with four memory channels. After the Memory Mirroring function is enabled, you can mirror important areas to improve the reliability of key areas and ensure that only a little memory capacity is lost. This function is disabled by default.


Memory Migration is used to reserve memory resources of a CPU to replace faulty memory resources without interrupting system operations.


To obtain all the system memory you need to disable from BIOS -> IntelRCSetup:
