SAPHANA 2.0 SPS4: Fast Restart Option via TMPFS
For restarting the HANA in case of activating parameter or in context of HSR the CS can be kept in TMPFS during maintenance.
This will reduce restart times also if your HW is not ready for pmem but not in case of linux reboot.
For LINUX reboot and keeping HANA TMPFS data in memory a PowerVM based solution is already in development process (outlook).
