I was thinking maybe about trying a Proxmox cluster across 6 nodes, and using containers for the Jellyfin media streaming stack here:  For storage, I have two 4tb drives, and I'd like to have them separated across two different nodes, but mirrored and preferably auto fail-over. Thoughts? Ideas?

I may have the options between two Mikrotik l009 routers or a single rb5009. Which route should I go?

Just bought Cyberpower OR700 1U UPS (20lbs). Will I need rack mount rails to support the back or will the cage nuts at the front be enough to support the UPS?
