DC Persistent Memory Module - Memory Mode

Memory modules must be installed in a specific order based on the memory configuration that you implement on your node. Below is the information of Memory Mode.

Note

Before installing DCPMM, refer to Configure Persistent Memory Module (PMem) for the requirements.

Following are all the combinations that are supported in this solution.

Memory Mode with one processor

Table 1. Memory Mode with one processor
D: DRAM DIMMs with 16 GB or larger capacity P: Only DC Persistent Memory Module (DCPMM) can be installed on the corresponding DIMM slots.
Configuration	Processor 1
Configuration	1	2	3	4	5	6	7	8	9	10	11	12
2 DCPMMs and 6 DIMMs	D		D		D	P	P	D		D		D
4 DCPMMs and 6 DIMMs	D		D	P	D	P	P	D	P	D		D
6 DCPMMs and 6 DIMMs	D	P	D	P	D	P	P	D	P	D	P	D
2 DCPMMs and 4 DIMMs	P		D		D			D		D		P

Note

2 DCPMMs and 4 DIMMs: one DIMM per processor channel configuration.
