Show Memory Resources
Show the total Intel Optane persistent memory resource allocation across the host server.
ipmctl show [OPTIONS] -memoryresources
The following shows persistent memory module resource allocation from a system configured in 100% AppDirect mode:
$ ipmctl show -memoryresources
MemoryType | DDR | PMemModule | Total

: Total DDR capacity that is inaccessible.InaccessibleCapacity
: Total system persistent memory capacity that is inaccessible due to any of:- Platform configuration prevents accessing this capacity. For example, MemoryCapacity is configured but MemoryMode is not enabled by platform FW (current Memory 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.
- Persistent 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 space (SPA).
- Capacity that is unusable because it has not been configured.
- PMem module configured capacity but SKU prevents usage. For example, AppDirectCapacity but PMem module SKU is MemoryMode only.
