Dell EMC PMem 100 Series User's Guide

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.
