PMem in App-direct mode
In App-direct mode, Windows creates two types of device objects for PMems :
● Physical INVDIMM device
● Logical Persistent Memory disk
Logical persistent memory disks get created after creating namespaces on PMem Physical disks.
When the system first boots into the Operating System, PMem devices get enumerated as physical INVDIMM devices under
Memory Devices in Device Manager.
Figure 16. Memory Devices in Device Manager
After PMem disks are configured over PowerShell, logical persistent memory disks show under Device Manager.
