● Mixing of DDR4 DIMM types (RDIMM, LRDIMM, and 3DS LRDIMM), within channels, for Integrated Memory Controller (iMC), or across sockets are not supported. ● Mixing of Intel Persistent Memory 200 series (BPS) operating modes (App Direct, Memory Mode) is not supported. ● If only one DIMM is populated on a channel, then the DIMM should always be populated in the first slot in that channel (white slot). ● If a Intel Persistent Memory 200 series (BPS) and a DDR4 DIMM are populated on the same channel, always plug Intel Persistent Memory 200 series (BPS) on second slot (black slot). ● If the Intel Persistent Memory 200 series (BPS) is configured in Memory Mode, the recommended DDR4 to Intel Persistent Memory 200 series (BPS) capacity ratio is 1:4 to 1:16 per iMC. ● Intel Persistent Memory 200 series (BPS)' cannot be mixed with other Intel Persistent Memory 200 series (BPS) capacities or NVDIMMs. ● Mixing different capacities of RDIMMs and LRDIMMs are not allowed when Intel Persistent Memory 200 series (BPS) is installed. ● Intel Persistent Memory 200 series (BPS) of different capacities are not allowed. ● VMware ESXi boot takes longer time when higher capacity of Intel Intel Persistent Memory 200 series (BPS) are configured in AppDirect mode. This is expected as background ARS is going on the interleave sets and needs to be completed prior the pMem datastore is mounted on ESXi. ● App Direct (AD) can be populated symmetrically or asymmetrically across sockets. ● In Memory mode (MM), symmetry across sockets is required. ● Memory mode is not supported for the 6+1, 8+1 and 12+2 configurations irrespective of DDR to Intel Persistent Memory 200 series (BPS) capacity ratio. ● In VMware ESXI environment, if BPS goal is changed between App Direct and Memory mode, it is recommended to sanitize the DIMMs before creating a new goal. ● Populate Intel Persistent Memory 200 series (BPS) in DIMM slot 1, unless Intel Persistent Memory 200 series (BPS) is the only DIMM in that channel and then populate in DIMM slot 0.
