Hello all, I need some advice on the best way to use a bunch of NVMe drives for my server. I use that box as a file/media server and lab with several VMs and containers currently running off the cache pool. Below is the current config:
Compute: Dual Intel Xeon 2680 v2, 320GB DDR3 ECC
Storage array: 8xSeagate Archive 8TB SMR(6 holding data and 2 parity disks)
Cache pool: 2*1TB SATA SSD + 2*500 GB SATA SSD strip mirrored
And this is what it is being upgraded(internal components swap) to:
Compute: Threadripper 3960x, 256gb DDR4
Storage(where I need your help): 8xIntel P4610 DC 6.4TB NVMe SSD
What would be the best way to set up those new drives and migrate data? Should I even bother with a cache pool since they are so much faster than the spinning rust? I was thinking about going raidz with no cache, since data would be spread across the disk at the block-level and not file-level maximizing throughput for those vdisks. Thoughts?
If I go the raidz route, how would I go about migrating data since /domains and /appdata are not visible in the share?
Thank you.
