PMEM vs SAP HANA Fast restart option
19
Scenario DCPMM Fast Restart Option
HANA restart Yes Yes
HANA service restart Yes Yes
HANA upgrade/service patch Yes Yes
Operating system update/service patch Yes No
Server reboot (planned) Yes No
Server reboot (HW failure) Yes No
Power outage Yes No
BIOS/firmware update Yes No
HW upgrade w/o Persistent Memory replacement Yes No
• The Fast Restart option is a bridge technology for environments with servers that do not support DCPMM.
• Like DCPMM, it provides less downtime, but not the cost efficiency of DCPMM.
Comparison table below indicates which cases in-memory data can be reused without reading data from persistent storage (disk).
