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.

Where do you find the bandwidth to do all that? NVME eats it up and the 40g too.

I did ran out of pcie, yeah :-( the network peaks at about 26gbit/s, which is the most you can squeeze out of pcie 3.0 x4. I could move the nvmes off the pcie 4.0 x16 (I have two m2 slots on the motherboard itself), but I planned to expand the nvme storage to 4x SSDs and I’m out of the pci lanes on the other end of the fiber either way (that box has all x16 going to the gpu)
