Hello all, I'm not sure where to go with questions these days, most of the mail = archives look pretty quiet and I didn't see one focused on storage = (maybe -scsi?). The forums seem active enough, but maybe more home user = focused? Anyhow, we're trying purchase a few servers (likely this Supermicro: = https://www.supermicro.com/en/products/system/UP/1U/SYS-111E-WR) and = since manufacturers don't seem to validate for FreeBSD these days, I was = hoping for some community input. Last time I looked into this NVMe (specifically the "U.2" format for = servers that includes hot swap) was supported in FreeBSD but hot swap = was kind of iffy. I don't think too many FreeBSD users/developers at = that time had the hardware, most people seemed to just be using an = on-board NVMe drive on desktop or laptop systems, and there's not any = real call for hot swap in that segment. I have a thread on the forums linked below, but really what I'm looking = to find is some larger orgs that are running NVMe drives and can confirm = hot swap works as expected, if there's any gotchas to be on the lookout = for, etc. Trying not to overcomplicate it, but we don't want to be stuck = with a bunch of servers that might be less stable than our current = SAS/SATA servers. We exclusively use ZFS, if that's useful info. Let me know if there's another list I should be bringing this too, it's = been a long time since I posted to a FreeBSD list. Thanks!
