I'm in the process of building two new servers and wanted some thoughts on getting the speediest storage I can. I already have quite a few SSDs but I'm not opposed to selling and purchasing more appropriate drives. Both servers will be used as VM hosts running 2019 as the hypervisor. I will be using dedupe so I only need about 1.5tb of useable storage. Redundancy is a must and VM performance is near the top of the list.
Server1: Epyc 7402p on a Supermicro H12 board (when available) with a built in LSI 3008 controller.
Server2: Xeon e-2286g also on an SM board with the built in intel sata software raid controller.
Available SSDs:
8x 1.92TB Toshiba HK4 SATA SSDs (so 4x per server, thinking raid 10)
4x 400GB P3700 NVMe SSDs
My current thought is to use 4x of the Toshiba drives in a raid 10 array on the LSI controller on server 1 and raid 10 on the intel controller on server 2. Plenty of space but only sata speeds.
I don't think I'll be using the NVMe drives as there is no way to use hardware raid and they are a bit too small.
I could use 4x SAS SSDs on server 1 if anyone has any suggestions on what to buy that would be noticeably faster than the Toshiba drives. 800GB per drive would be a perfectly good size, dedupe is so efficient I fit over a dozen VMs in a couple hundred GB of space.
