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.

      Average load 800W is 0.8kW24h30d=576kWh/M

      Which is over 172€ on a 30ct/kWh contract.

        Wow! I’m paying 10.5¢/kWh for electricity at home here in the US; it’s a little below the national average but not dramatically.

          Yeah, we pay a lot. We also got one of the lowest downtimes regarding electricity, on average approximately 10minutes per year…so that’s kind of a (small) advantage you get for the premium price
