Because it's almost impossible to purchase the equipment required to
convert old drive bays to u.2 etc.
The M.2's we purchased are enterprise class.

Why use such a card and M.2 drives that I suspect aren’t enterprise-class?
Instead of U.2, E1.s, or E3.s ?

Hello,
So we were going to replace a Ceph cluster with some hardware we had laying
around using SATA HBAs but I was told that the only right way to build Ceph in
2023 is with direct attach NVMe.
Does anyone have any recommendation for a 1U barebones server (we just drop in ram
disks and cpus) with 8-10 2.5" NVMe bays that are direct attached to the
motherboard without a bridge or HBA for Ceph specifically?
Thanks,
-Drew

Hi
You need to use PCIe card with a PCIe switch, cards with 4 x m.2 NVME are cheap
enough around $USD180 from Aliexpress.
There are companies with cards which have many more m.2 ports but the cost goes
up greatly.
We just build a 3x1RU G9 HP cluster with 4 x 2T m.2 NVME using Dual 40G
Ethernet ports and dual 10G Ethernet and a second hand Arisa 16 port 40G switch.
It works really well.
Cheers
Mike
