So, it is Linux MD RAID with some management addons. I prefer to stay far
away from such addons.
A nice feature is the LED management, but who needs it if you have proper
monitoring and are not in the DC anyway?
I prefer standard U.2 NVMe SSDs connected via PCIE to the CPU. Works
wonderfully on AMD EPYC so I expect the same on Intel also.
Just don't forget to adjust raid speed limits. I have
dev.raid.speed_limit_max = 10000000
dev.raid.speed_limit_min = 15000
to enjoy full sync speed.
Regards,
Simon
