PowerEdge 15G and 14G servers with Intel Xeon CPUs combined with Intel Optane memory can lower the TCO for SAP HANA environments and increase the overall memory capacity in a machine.
Note: PowerEdge 16G servers do not support Intel Optane memory.
Intel Optane memory on SAP HANA allows up to 15 TB of data to be stored within one four-socket server beyond the physical capabilities of DRAM. SAP HANA supports PMEM only in App Direct mode for production systems. At the time of writing, memory mode is supported for nonproduction systems.
Here are the memory limits:
Note: PMEM works only with SAP HANA-certified Intel Xeon 2nd and 3rd Generation servers.
SAP HANA supports the following minimum operating system versions with PMEM:
