Partitioning memory modules into volatile and non-volatile portions

A method, comprising:

• partitioning, by a memory controller, a subset of a plurality of memory modules into non-volatile portions and volatile portions;
• identifying, by the memory controller, persistent data to be backed up in response to an interruption of primary power supply to the plurality of memory modules;
• and
• moving, by the memory controller, the persistent data from the volatile portions of the plurality of memory modules to the non-volatile portions of the plurality of memory modules, in response to the interruption of primary power supply, using backup power provided by a backup power supply.

A non-transitory computer-readable storage medium encoded with instructions executable by a processor of a computing system, the computer-readable storage medium comprising instructions to:

• partition a subset of a plurality of memory modules into non-volatile portions and volatile portions;
• identify persistent data to be backed up from the volatile portions of the plurality of memory modules in response to a power loss condition;
• and
• copy the persistent data from the volatile portions to the non-volatile portions of the plurality of memory modules in response to the power loss condition, using backup power from a backup power supply.
