DCPMM Installation order: App Direct mode with six 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.
• Processors 5 and 6 are installed in the lower system board of the upper 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
