online help.
Installing DIMMs
The server supports DCPMMs and DRAM DIMMs (both LRDIMM and RDIMM supported).
Compared with DRAM DIMMs, DCPMMs provide larger capacity and can protect data from getting
lost in case of unexpected system failures.
Both DCPMMs and DRAM DIMMs are referred to as DIMMs in this document, unless otherwise
stated.
Guidelines
WARNING!
The DIMMs are not hot swappable.
You can install a maximum of 12 DIMMs for each processor, six DIMMs per memory controller. For
more information, see "DIMM slots."
