Memory Mirroring is a RAS feature that enables duplicating memory content at a remote DIMM in the partition. This capability enables high data availability from memory subsystem. Fault Resilient Memory enables you to select the segments of system memory that contains the most critical code. Sample Memory Configurations The following table shows sample memory configurations for a single processor that follow the appropriate memory guidelines stated in this section. NOTE: DIMMs populated must be identical for each riser. In the mirroring mode, only one of the two CPUs is populated. NOTE: 64GB LRDIMMs are supported by the system. Table 2.

Memory Mirroring is a RAS feature that enables duplicating memory content at a remote DIMM in the partition. This
capability enables high data availability from memory subsystem. Fault Resilient Memory enables you to select the
segments of system memory that contains the most critical code.
Sample Memory Configurations
The following table shows sample memory configurations for a single processor that follow the appropriate memory
guidelines stated in this section.
NOTE:
DIMMs populated must be identical for each riser. In the mirroring mode, only one of the two CPUs is
populated.
NOTE:
64GB LRDIMMs are supported by the system.
