Installation order: memory sparing with six processors
Memory module installation order for memory sparing with six processors installed in the server.
The following table shows the DIMM population sequence for memory sparing when six processors are
installed.
• Processors 1 and 2 are installed in the lower system board of the lower compute tray.
• Processors 3 and 4 are installed in the upper system board of the lower compute tray.
• Processor 5 is installed in the lower system board of the upper compute tray.
• Processor 6 is installed in the upper system board of the upper compute tray (processor slot 7).
Note: An even number of DIMMs is required for memory sparing.
