8 DIMM configuration changes The following PMem migration scenarios are supported: ● Replacement of System Board due to failure All DIMMs must be re-populated in the exact same slots. PMems and data content will be available for customer application access after the board has been restored to the same configuration as the original board. System Restore will automatically restore the BIOS configuration on the replacement board, including the PMem Passphrase, if it is set. ● Replacing bad DIMM In the case of a failed PMem, any data associated with the PMem would be lost. The region and interleave set on the failed PMem must be recreated once it is replaced. The user must use BIOS Setup to create a new goal for the affected PMem. NOTE: Any remaining persistent memory data on Intel PMem must be backed up prior creating a goal. The goal creation process deletes all namespaces, regions, and data stored on the PMems on the selected CPUs. If a Security Passphrase is enabled, the new persistent memory region is protected with the system PMem passphrase. NOTE: Adding or removing PMems to an existing PMem configuration is not supported, and not validated. It is recommended that customers back up all PMem data to another storage device before making any PMem configuration changes. Once the server is reconfigured to the new PMem configuration, the customer can create a goal configuration and restore data back to PMems. DIMM configuration changes 33

DIMM configuration changes
The following PMem migration scenarios are supported:
●
Replacement of System Board due to failure
All DIMMs must be re-populated in the exact same slots. PMems and data content will be available for customer application
access after the board has been restored to the same configuration as the original board. System Restore will automatically
restore the BIOS configuration on the replacement board, including the PMem Passphrase, if it is set.
●
Replacing bad DIMM
In the case of a failed PMem, any data associated with the PMem would be lost. The region and interleave set on the failed
PMem must be recreated once it is replaced. The user must use BIOS Setup to create a new goal for the affected PMem.
NOTE:
Any remaining persistent memory data on Intel PMem must be backed up prior creating a goal. The goal creation
process deletes all namespaces, regions, and data stored on the PMems on the selected CPUs. If a Security Passphrase is
enabled, the new persistent memory region is protected with the system PMem passphrase.
NOTE:
Adding or removing PMems to an existing PMem configuration is
not supported
, and not validated. It is
recommended that customers back up all PMem data to another storage device before making any PMem configuration
changes. Once the server is reconfigured to the new PMem configuration, the customer can create a goal configuration and
restore data back to PMems.
