New consolidated data storage server sanity check

I’m thinking of consolidating 5 of my NAS system down to a single server.

Right now, my hard drives are kind of scattered between those systems and then two plan is going to be moving to Proxmox VE 7.3-3, running ZFS.

I wanted to run the idea of setting up 4 vdevs, each with 8 drives each, and each vdev being a raidz2 vdev.

Two of the vdevs will consist of 6 TB drives (8 x 6 x 2) and two of the vdevs will consist of 10 TB drives.

If I have such a massive storage pool like that, but broken out into vdevs that are no more than 8-wide, is there anything that I should be aware of before setting something up like this?

Any “gotchas” that I should be thinking about or be weary of?

(I tested this configuration in a VM environment with TrueNAS and it didn’t seem to have an issue with it, but I wanted to double check before deploying Proxmox on bare metal, and then using Promox’s ZFS capabilities to set something like this up.)

Your help is greatly appreciated.

Thank you.

ZFS deals with Imbalanced VDEV’s by dividing the data based on the size of each one.
