Show Memory Resources

Show the total Intel Optane DC persistent memory resource allocation across the host server.

ipmctl show [OPTIONS] -memoryresources

Example

Show persistent memory module resource allocation.

$ ipmctl show -memoryresources

Capacity=1517.0 GiB
MemoryCapacity=0.0 GiB
AppDirectCapacity=1512.0 GiB
UnconfiguredCapacity=0.0 GiB
InaccessibleCapacity=5.0 GiB
ReservedCapacity=0.0 GiB

Return Data

• MemoryCapacity: Total usable system persistent memory for Memory Mode.

• AppDirectCapacity: Total usable system persistent memory for App Direct mode.

• UnconfiguredCapacity: Total system persistent memory capacity that is unusable because it has not been configured.

• ReservedCapacity: Total system persistent memory capacity that is reserved. This capacity is the persistent memory partition capacity (rounded down for alignment) less any App Direct capacity. Reserved capacity typically results from a Memory Allocation Goal request that specified the Reserved property. This capacity is not mapped to system physical address (SPA) space.

• InaccessibleCapacity: Total system persistent memory capacity that is inaccessible due any of:

  • Platform configuration prevents accessing this capacity. e.g. MemoryCapacity is configured but MemoryMode is not enabled by platform FW (current operating mode is 1LM).

  • Capacity is inaccessible because it is not mapped into the system physical address space (SPA). This is usually due to platform firmware memory alignment requirements.

  • Intel Optane DC persistent memory is configured but SKU prevents usage. e.g. AppDirectCapacity but SKU is MemoryMode only.
