Consider the following recommendations for the PowerFlex R6525 AMD EPYC compute nodes.
- PowerFlex R6525 nodes are updated with BIOS firmware and system profile is set to performance mode.
- Red Hat Enterprise Linux 8.4 TuneD has Oracle profile. Use the Oracle profile to set the operating system level performance settings according to Oracle from the kernel level to memory and network settings. For more information, see Appendix 1. Tuning the system with TuneD.
- Disable Linux kernel auto NUMA balancing.
echo 0 > /proc/sys/kernel/numa_balancing
- Set I/O scheduler to none to get better performance with lower CPU overhead.
#cat /sys/block/scinia/queue/scheduler
[none]
