Persistent memory modulePersistent memory module relocation guidelines relocation guidelines
Observe the relocation guidelines when doing the following:
When relocating persistent memory modules to another DIMM slot on the server.
When relocating persistent memory modules to another server.
When reinstalling persistent memory modules after replacing the server system board.
IMPORTANT:IMPORTANT:
When data must be preserved, Hewlett Packard Enterprise strongly recommends that you perform a manual backup of
all user data on the persistent memory modules before changing the goal configuration or performing relocation
procedures.
Requirements for relocating Requirements for relocating persistent memory modulespersistent memory modules or a set of or a set of persistent memory modulespersistent memory modules when when
the data must be preservedthe data must be preserved
The destination server hardware must match the original server hardware configuration.
All System Utilities settings in the destination server must match the original System Utilities settings in the original server.
If persistent memory modules are used with Persistent Memory Interleaving set to Enabled in the original server, do the following:
Install the persistent memory modules in the same DIMM slots in the destination server.
Install the entire interleaved set (all the DIMMs and persistent memory modules on the processor) on the destination server.
If any of the requirements cannot be met during relocation, do the following:
Manually back up the persistent memory data before relocating persistent memory modules to another server.
Relocate the persistent memory modules to another server.
Sanitize all persistent memory modules on the new server before using them.

If persistent memory modules are encrypted with local key management, either manually retrieve the persistent memory module
passwords from the server (user-generated passwords only) or export a password file to a USB key.
Hewlett Packard Enterprise recommends exporting the password file to a USB key.
Follow the requirements for relocating persistent memory modules or a set of persistent memory modules when the data must be
preserved.
Do one of the following:
If persistent memory modules are encrypted with local key management, either manually enter the persistent memory module
passwords in the System Utilities or import the password file from the USB key.
If persistent memory modules are encrypted with remote key management, enroll the HPE iLO in the key management server to
provide access to the data on the persistent memory modules.

Move the persistent memory modules to the new location and sanitize all persistent memory modules after installing them to the new
location.
Observe the DIMM and persistent memory module population guidelines.
Observe the process for removing a persistent memory module.

Review and configure the system settings for Intel Optane persistent memory for HPE.
