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