What's your server wattage? (lemmy.world)

I'm in the process of wiring a home before moving in and getting excited about running 10g from my server to the computer. Then I see 25g gear isn't that much more expensive so I might was well run at least one fiber line. But what kind of three node ceph monster will it take to make use of any of this bandwidth (plus run all my Proxmox VMs and LXCs in HA) and how much heat will I have to deal with. What's your experience with high speed homelab NAS builds and the electric bill shock that comes later? Epyc 7002 series looks perfect but seems to idle high.

On the Sata SSD ceph storage. That's just live stuff on the containers/vms. I'm at 20% usage of the 70TiB usable at the moment. I don't use it all that heavily. Because of the way ceph works it's really ~23 TiB of usable space and ~4.5 TiB written since it writes 3 copies in my cluster.

On the slow storage node it's running Truenas with 28 spinning disks at 16TB each. 2 hot spares, and 2 ssds each for cache, log, and metadata (eating up total of 36 bays). That's 342.8TiB usable after raidz nonsense. And I'm 56% usage. I have literally everything I've done that I cared to save from like 2005 or 2006 or so. Backups for the ceph storage (PBS). Backups for computers I've had over the years. Lots of linux ISOs(105TiB) archived, including complete sets of gaming (37TiB) variants. Oh and my full steam library as well which currently sits at 14TiB. Flashpoint takes up a few TiB as well...
