Server hardware configuration
PMem is supported in R650, R750, R750xa, MX750c, XR11 and XR12 PowerEdge servers with third-generation Intel Xeon
Scalable Processors of Gold and Platinum grade. See PMem configurations for a list of fully supported and validated PMem
configurations in two-socket servers. Four-socket configurations are a direct scale up of two-socket configurations.
NOTE: For PowerEdge R750 or R750xa, 1400 W or 2400 W PSUs are required when Intel PMems are present in the
system. If these guidelines are not followed, the system may not have sufficient power holdup in an AC loss scenario to
flush in-flight data contents to persistent media. All systems built from Dell Technologies factories will be pre-configured to
meet these guidelines.
DIMM installation and removal
Industry standard DIMM practices and procedures must be followed while handling, installing, or removing PMem memories.
For more details on procedures for installing or removing modules, see the Standard Practices and Procedures - Module
Insertion Procedure for DIMM and miniDIMM Connectors documentation by JEDEC.
JEDEC Standards (www.jedec.org): Document Number SPP-023B.
PMem hardware configuration
PMem recommended topologies
This section contains the high-level introduction on PMem configuration and provisioning concepts.
The following topologies are recommended per processor socket. For multiple socket systems with more than one PMem, each
socket should be populated identically.
See the Installation and Service Manual for memory installation guidelines of respective servers.
NOTE:
The following image and table is for reference which displays the PowerEdge R750 processor and DIMM slot
locations.
