License Required iDRAC Express or iDRAC Enterprise Dependency Not applicable BIOS.MemSettings.RawCapacity (Read or Write) Description Total NVDIMM raw size in the system. Legal Values None Default Value Not Applicable Write Privilege Server Control License Required iDRAC Express or iDRAC Enterprise Dependency Not applicable BIOS.MemSettings.RedundantMem (Read or Write) Description Enables or disables the redundant memory feature. This feature can be enabled only if a valid redundant memory configuration is detected. When Mirror Mode is enabled, the server maintains two identical copies of data in memory. This feature allows the system to continue running even during a catastrophic memory failure. NOTE: In Mirror Mode, only half of the memory size is reported to the OS. When Spare Mode is enabled, certain sets of DIMMs or a portion of these DIMMs called a Rank will be set aside as the spare memory. When a preset threshold of correctable errors has been reached on an active DIMM rank, the contents of that rank will be copied to the spare memory to prevent catastrophic memory failure. Note that in Spare Mode, the memory size reported to the OS does not include the spare portion. Default: Disabled For Spare Mode: Has a dependency on DIMM population where within a given channel, multi-rank DIMM or multi single rank DIMM needs to be populated. For Mirror Mode and Lockstep Mode: Has a dependency on DIMM population where corresponding channnels for each socket (Channel0 and Channel2, Channel1 and Channel 3) needs to be populated and populated idenditally.
