Lenovo ThinkSystem SR860 Setup Manual page 86

Example: Intel Xeon 5215L and Xeon Platinum 8280M
To verify if the presently installed processors support DCPMMs, examine the four digits in the processor
description. Only the processor with description meeting both of the following requirements 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)
– Medium memory tier (M): The processors with M after the four digits (for example: Xeon Platinum
8280M)
– Other: Other processors that support DCPMMs (for example: Intel Xeon Gold 5222)
In addition, you can take advantage of a memory configurator, which is available at the following site:

DC Persistent Memory Module (DCPMM) setup
Follow the instructions in this section to complete required setup before installing DCPMMs for the first time,
determine the most suitable configuration, and install memory modules accordingly.
Complete the following steps to finish system setup to support DCPMMs, and install the memory modules
according to the designated combination.
1. Update the system firmware to the latest version that supports DCPMMs (see
page 134).
2. Make sure to meet all the following requirements before installing DCPMMs.
• All the DCPMMs that are installed must be of the same part number.
• All the DRAM DIMMs that are installed must be of the same type, rank, and capacity with minimum
capacity of 16 GB. It is recommended to use Lenovo DRAM DIMMs of the same part number.
• 64 GB 3DS LRDIMMs are not supported to be mixed with DCPMMs.
3. Refer to "DCPMM and DRAM DIMM installation order" in Memory Population Reference to determine
the most suitable combination and the following:
• Number and capacity of the DCPMMs and DRAM DIMMs to install.
• Check if the presently installed processors support the combination. If not, replace the processors
with ones that support the combination.
4. Based on the determined DCPMM combination, acquire the DCPMMs, DRAM DIMMs and processors if
necessary.
5. Replace the processors if necessary (see "Processor and heat sink replacement" in Maintenance
Manual).
6. Remove all the memory modules that are installed (see "Remove a memory module" in Maintenance
Manual).
7. Follow the slot combination in "DCPMM and DRAM DIMM installation order" in Memory Population
Reference to install all the DCPMMs and DRAM DIMMs (see
8. Disable security on all the installed DCPMMs (see
page 139).
9. Make sure the DCPMM firmware is the latest version. If not, update it to the latest version (see
sysmgt.lenovofiles.com/help/topic/com.lenovo.lxca.doc/update_fw.html
10. Configure DCPMMs so that the capacity is available for use (see
(PMem)" on page 139).
