HPE Persistent Memory module relocation guidelines

Observe the relocation guidelines when doing the following:

  • When relocating HPE Persistent Memory modules to another DIMM slot on the server.

  • When relocating HPE Persistent Memory modules to another server.

  • When reinstalling HPE Persistent Memory modules after replacing the server system board.

IMPORTANT:

When data must be preserved, Hewlett Packard Enterprise strongly recommends that you perform a manual backup of all user data on the HPE Persistent Memory modules before changing the goal configuration or performing relocation procedures.

Requirements for relocating HPE Persistent Memory modules or a set of HPE Persistent Memory modules when the 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 HPE Persistent Memory modules are used with Persistent Memory Interleaving set to Enabled in the original server, do the following:

    • Install the HPE Persistent Memory modules in the same DIMM slots in the destination server.

    • Install the entire interleaved set (all the DIMMs and HPE 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 HPE Persistent Memory modules to another server.

    • Relocate the HPE Persistent Memory modules to another server.

    • Sanitize all HPE Persistent Memory modules on the new server before using them.

Requirements for relocating encrypted HPE Persistent Memory modules or a set of HPE Persistent Memory modules when the data must be preserved

  • If HPE Persistent Memory modules are encrypted with local key management, either manually retrieve the HPE 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 HPE Persistent Memory modules or a set of HPE Persistent Memory modules when the data must be preserved.

  • Do one of the following:

    • If HPE Persistent Memory modules are encrypted with local key management, either manually enter the HPE Persistent Memory module passwords in the System Utilities or import the password file from the USB key.

    • If HPE 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 HPE Persistent Memory modules.

Requirements for relocating HPE Persistent Memory modules or a set of HPE Persistent Memory modules when the data does not have to be preserved

  • Move the HPE Persistent Memory modules to the new location and sanitize all HPE Persistent Memory modules after installing them to the new location.
  • Observe the DIMM and HPE Persistent Memory module population guidelines.
  • Observe the process for removing an HPE Persistent Memory module.
  • Observe the process for installing an HPE Persistent Memory module.
  • Review and configure the system settings for HPE Persistent Memory.
