Procedure to test a M2 NVME to Oculink adapter card prior to adding said drives to my cache pool

Featured Replies

Hello all,

I got a new server pretty recently. It has 2x 3.5" ssd slots in the back, and I had 2x SSDs in my old server, so easy peasy, worked great.

I am intrigued by the fact the new server also has 4x PCIe 3 NVME Oculink headers on it, expressly for adding 4x NVME drives. I didn't see any good backplanes for this functionality so I landed on this pretty sketch adapter:

The reviews I've seen on these are pretty mixed. One review noted that the actual m2 slots ripped off with zero effort because of jank soldering, and other fun stuff like that. I wound up getting the best one I saw and hoping for the best.

I also have new drives on the way to populate into said card.

I am looking for suggestions of how I can absolutely pound the hell out of those drives once I install them assuming it all connects and no ports physically rip off? I am guessing I would add them as unassigned devices, validate them with some kind of punishing test, and then expand my cache pool onto it once done - it's that middle part I am looking for advice for, what kind of software or suchlike that will really hammer the drives and try to pop a fault before anything that matters is on them. Can I just repeatedly preclear them, or does that really only work with mechanical drives?

Thanks for any advice you might have on this!
