However, use either R-DIMM (Registered DIMM: 8 GB/16 GB/32 GB) memory or
LR-DIMM (Load Reduced DIMM: 64 GB) memory.
Table 2-1 lists the supported memory installation configurations.
Configuration with memory mirroring
■
Install exactly 8 or 16 memory modules. That is, the installed memory modules are
in sets of 8.
■
Install memory of the same capacity and rank within each set of eight modules.
■
You can install memory of different capacities among the sets of eight modules.
However, use either R-DIMM (Registered DIMM: 8 GB/16 GB/32 GB) memory or
LR-DIMM (Load Reduced DIMM: 64 GB) memory.
Table 2-2 lists the supported memory installation configurations.
Figure 2-4 shows combinations of mirrored memory. The 4 modules at a and the 4
modules at b are mirrored in an 8-module combination, and the 8 modules at a and c
and the 8 modules at b and d are mirrored in a 16-module combination.
2.2.2 Checking memory information
Check the type and size of the memory by using the showhardconf command of the
XSCF firmware.
1. Log in to the XSCF shell.
2.
Execute the showhardconf command to check the memory information.
