DC Persistent Memory Module (DCPMM) installation order
This section contains information of how to install DC Persistent Memory Module (DCPMM) and DRAM DIMMs.
For more information about the processors compatibility, see Lenovo ServerProven website.
Before installing DCPMMs and DRAM DIMMs, refer to DC Persistent Memory Module (DCPMM) setup and make sure to meet all the requirements.
To verify if the presently installed processors support DCPMMs, examine the four digits in the processor description. Only the processors with description meeting both of the following requirements support DCPMMs.
The first digit is 5 or a larger number.
The second digit is 2.
Example: Intel Xeon 5215L and Intel Xeon Platinum 8260M
If the presently installed processors do not support DCPMMs, replace them with the processors that support DCPMMs.
- Supported memory capacity range varies with the following types of DCPMMs.
Large memory tier (L): The processors with L after the four digits (for example: Intel Xeon 5215L)support up to 4.5 TB of memory capacity per processor
Medium memory tier (M): The processors with M after the four digits (for example: Intel Xeon Platinum 8260M)support up to 2 TB of memory capacity per processor
Other: Other processors that support DCPMMs (for example: Intel Xeon Gold 5222)support up to 1 TB of memory capacity per processor
