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

I know they’re gonna be a power suck lol. Three mini PCs, a SFF PC, 4-bay hard drive docking station, 8-port switch, and a RPi0w… Hoping for a max of 200W, but I suppose we’ll see what happens 🫤

You might need to lower your expectations

  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. 🙃

I see your 4-bay docking station and raise my 20-bay storage server. I even stopped counting how much the hardware costs for it :p

  It’s attached via USB to a 2014-era Mac Mini. Honestly not a huge fan of it.
  
  The kicker is that I’m upgrading it to a 7th-gen based server soon. My dad gave me an old Pentium 4-powered HP Proliant DL110, the case of which has 10x 3.5" drive bays, and is fully ATX compatible, so I’m gonna drop in a 7th gen mobo with Pentium G4560T (already have that on my desk), a newer PSU, and an HBA card. Don’t need a ton of processing power for a dedicated NAS running OMV - just a lot of expansion capacity.
