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.
