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.

Intel g3930, 2x8GB RAM, 2x SSD, 1x HDD, integrated 1GB LAN = 30-35W. Kinda cheap here, 30-35€ a year

[–] vividspecter@lemm.ee 1 points 5 months ago

Systems themselves are all around 5-20W, although the ones with mechanical HDDs obviously add their own idle usage.

About 120W total for:

  • 2 Proxmox hosts with 4 spinning disks between them
  • Opnsense firewall
  • 24 port GbE switch
  • Fiber ONT
  • Unifi AP

Actually if anyone has advice I'd love to hear. My server is a b450 mobo with an athlon 320ge. Even with no hard drives spinning it uses 65watts. I don't understand how it is possible. 6 hard drives bring it to 85-90. Running truenas if it matters

I keep it off most of the time to safe power, I was expecting especially with such a cou much lower wattage, like under 20 idle. My assumption is the power supply can't get low enough.

What CPU governor are you using? I saved about 40W idle powerdraw switching to powersave vs the default on a Ryzen 9 3900X.

[–] Soggytoast@lemm.ee 1 points 5 months ago (1 children)

Is that a bios or truenas setting? The CPU is only 35 watt max

[–] boonhet@lemm.ee 1 points 5 months ago

Operating system so TrueNAS in your case

[–] Aux@lemmy.world 1 points 5 months ago

I have four Raspberry Pi 4 running, so that's 15W max each or 60W max total. Usually they consume much much less.
