Move UnRaid from metal to Proxmox (lemmy.ml)

I have a trusty UnRaid server that has been running great for almost 3 years now, with some kinks and headaches here and there, but mostly very stable. Now I'm entertaining the idea of setting that box up with ProxMox, and running UnRaid virtualized. The reason being that I want to use UnRaid exclusively as a NAS and then run all dockers and VMs on ProxMox (at least that's how I'm picturing it). I would like to know your opinion on this idea. All I have is Nextcloud, Immich, Vaultwarden, Jellyfin, Calibre, Kavita and a Windows VM I use to update some hardware every now and then. I mainly want to do that for the backup capabilities in ProxMox for each instance. Storage is not a concern, and I have 64GB of ECC Ram running in that box. What are the Pros and Cons, or is it even worth it to move all this to ProxMox?

It depends on your needs. It's entirely possible to just format a bunch of disks as xfs and setup some mount points you hand to a union filesystem like mergerfs or whatever. Then you would just hand that to proxmox directly as a storage location. Management can absolutely vary depending how you do this.

At its heart it's just Debian so it has all those abilities of Debian. The web UI is more tuned to vm/lxc management operations. I don't really like the default lvm/ext4 but they do that to give access to snapshots.

I personally just imported an existing zfs pool into proxmox and configured it to my liking. I discovered options like directly passing datasets into lxc containers with lxc options like lxc.mount.entry

I recently finished optimizing my proxmox for performance in regards to disk io. It's modified with things like log2ram, tmpfs in fstab for /tmp and /var/tmp, tcp congestion control set to cubic, a virtual opnsense heavily modified for 10gb performance, a bunch of zfs media datasets migrated to one media dataset and optimized for performance. Just so many tweaks and knobs to turn in proxmox that can increase performance. Folks even mention docker I've got it contained in an lxc. My active ram usage for all my services down to 7 gigs and disk io jumping .9 - 8%. That's crazy but it just works.
