DCPMM Installation order: App Direct mode with four processors

When implementing App Direct Mode, any supported DIMMs in any capacity can be installed.

When eight processors are installed in the server:

  • 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.

Several configurations are supported with implementing App Direct mode with eight processors:

  • 6 DCPMMs/6 DRAM DIMMs per processor

  • 4 DCPMMs/6 DRAM DIMMs per processor

  • 2 DCPMMs/8 DRAM DIMMs per processor

  • 2 DCPMMs/6 DRAM DIMMs per processor

  • 2 DCPMMs/4 DRAM DIMMs per processor

  • 1 DCPMM/6 DRAM DIMMs per processor

  • 1 DCPMM in the system

6 DCPMMs/6 DRAM DIMMs per processor​
