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 DCPMM, and install the memory modules
according to the designated combination.
1. Update the system firmware to the latest version that supports DCPMM (see "Update the firmware" in
Setup Guide).
2. Make sure to meet all the following requirements before installing DCPMMs.
• All the DCPMMs that are installed must be of the same Lenovo part number.
• All DRAM memory modules 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 memory modules of the same
part number.
3. Refer to DCPMM installation rules to determine the most suitable combination and the following:
• Number and capacity of the DCPMMs and DRAM memory modules 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 memory modules and
processors if necessary.
5. Remove all the memory modules that are installed.
6. Follow the slot combination in DCPMM installation rules to install all the DCPMMs and DRAM memory
modules.
7. Disable security on all the installed DCPMMs (see "Configuring DC Persistent Memory Module
(DCPMM)" on page 12).
8. Make sure the DCPMM firmware is the latest version. If not, update it to the latest version (see
update)
).
9. Configure DCPMMs so that the capacity is available for use (see "Configuring DC Persistent Memory
Module (DCPMM)" on page 12.
Configuring DC Persistent Memory Module (DCPMM)
Follow the instructions in this section to configure DCPMMs and DRAM DIMMs.
