AppDirect
The following shows persistent memory module resource allocation from a system configured in 100% AppDirect mode:
1
$ ipmctl show -memoryresources

Return Data
Volatile DDR Capacity: Total DDR capacity that is used as volatile memory.Volatile PMem module Capacity: Total PMem module capacity that is used as volatile memory.Total Volatile Capacity: Total DDR and PMem module capacity that is used as volatile memory.AppDirect PMem module Capacity: Total PMem module capacity used as persistent memory.Total AppDirect Capacity: Total DDR and PMem module capacity used as persistent memory.Cache DDR Capacity: Total DDR capacity used as a cache for PMem modules.Total Cache Capacity: Total DDR capacity used as a cache for PMem modules.Inaccessible DDR Capacity: 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.
Total Inaccessible Capacity: Total capacity of DDR and PMem module that is inaccessible.Physical DDR Capacity: Total physical DDR capacity populated on the platform.Physical PMem module Capacity: Total physical PMem module capacity populated on the platform.Total Physical Capacity: Total physical capacity populated on the platform.
