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.

I would create a raidz pool, to migrate the data you can copy over LAN, using rsync for example.

The problem with that option is that it's all happening on the same system... 😅 . I currently have a plus license. Can I upgrade to pro to remove the disk number limit and do the copy internally? Or is going the external route the only way?
