Mixed Memory Mode
In this mode, some percentage of DCPMM capacity is directly accessible to specific applications (App Direct), while the rest serves as system memory. The App Direct part of DCPMM is displayed as persistent memory, while the rest of DCPMM capacity is displayed as system memory. DRAM DIMMs act as cache in this mode.
Note
Before installing DC Persistent Memory Module (DCPMM), refer to Memory configuration and Configure DC Persistent Memory Module (DCPMM) for the requirements.
