Mixed Memory Mode
In this mode, some percentage of PMEM capacity is directly accessible to specific applications (App Direct),
while the rest serves as system memory. The App Direct part of PMEM is displayed as persistent memory,
while the rest of PMEM capacity is displayed as system memory. DRAM DIMMs act as cache in this mode.
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.
