Mixed Memory Mode
In Mixed Memory Mode, 1-99% of DCPMM capacity acts as system memory. 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.
When implementing Mixed Memory Mode, any supported DIMMs in any capacity can be installed.
