Comment on Got myself some energy monitoring Zigbee plugs and made an interesting discovery

  FYI - the cluster is pulling 115 watts.

  • 1x Mac mini 2014, running OMV as a dedicated NAS (i5-4308U, 16GB RAM)
  • 4-bay Sabrent DS-SC4B, attached to Mac mini (3x 4TB WD Reds in RAID5, 1x 4TB WD Black as hot spare)
  • 1x 8TB WD backup drive (it’s something)
  • 2x HP Elitedesk 800 G3 mini (or G4, don’t remember), both running Proxmox (i7-7700T, 32GB RAM each)
  • 1x Dell Optiplex 7050 SFF running Proxmox (i7-7700, 32GB RAM)

  All running multiple VMs (Docker and other) and LXC containers.

  I’m impressed, honestly. I was expecting 200+ watts minimum. It’ll be interesting to see the spikes as it’s used over time.

    I’m surprised! Seems like it should be more, but I haven’t done any wattage calculations in a while, so maybe power efficiency really has gotten that much better.

    Do you know if the drives were spun up or down at the time? I know idle vs. active makes a difference, but if they were spun down entirely, that’s kind of cheating.

      I watched it as it booted, didn’t pull much more than 150 watts. But it’ll be interesting to see how it goes over time.

  Yeah… I know. 🙃
