App Direct Mode
In this mode, PMEMs act as independent and persistent memory resources directly accessible by specific
applications, and DRAM DIMMs act as system memory.
Note: When adding one or more DIMMs during a memory upgrade, you might need to remove some DIMMs
that are already installed to new locations.
