Finally got the 2x Supermicro NVME Gen4 re-timer cards working.
Driving 8x 2TB Samsung Gen4 NVME in RAID0 using RAIDIX Era.
Getting ~40 GBytes/second sequential read speed, still tweaking to be done.
Out of interest why have you got the CPU Cooler at 90° to the airflow?
It’s an AMD EPYC motherboard, cooler designed for Threadripper which has a 90-deg socket orientation.
I tried a dedicated EPYC 4U cooler with correct orientation, but it performed worse than this Noctua.
