Memory Configuration Parameters
DescriptionName
How the memory reliability, availability, and serviceability
(RAS) is configured for the server. This can be one of the
following:
• —System performance is optimized.
• Mirroring—System reliability is optimized by using half
the system memory as backup.
• Sparing—The system reserves some memory for use in
the event a DIMM fails. If that happens, the server takes
the DIMM offline and replaces it with the reserved
memory. This option provides less redundancy than
mirroring, but it leaves more of the memory available for
programs running on the server.
Select Memory RAS
Whether the BIOS supports NUMA. This can be one of the
following:
• Disabled—The BIOS does not support NUMA.
• Enabled—The BIOS includes the ACPI tables that are
required for NUMA-aware operating systems. If you
enable this option, the system must disable Inter-Socket
Memory interleaving on some platforms.
