Currently my UPS is reporting 207 watts, that’s with a unraid server (3600 + 32GB ram + 2060 super for plex, and 6 drives), a mini pc for pf sense, a rpi 4 running pihole and vpn server, a single poe ap, a modem, and security cameras… it can spike to 250w with multiple encodes going on from family … but overall not bad… I did have a dedicated 20A switch installed for just my network closet as well
Mine has been idling around 300-400 watts. I’ve recently been making some changes that have it running more than usual. I’m hoping in the next week I will get it back below 300 watt idle. With the space I have and the current cost of solar panels I basically offset the entire labs electric usage with about $800 worth of solar gear. So I haven’t stressed too much about electric use.
I went with simple micro-inverters (www.amazon.com/dp/B09N8T2741/) paired with some standard panels (www.amazon.com/dp/B0BRKK73QN/) Micro-inverters can’t be used when doing a full off-grid system but they are great at reducing energy bills. Super easy install that required no change to my home’s electric circuits.
I’ve got:
R720 w/ 2697v2s, 12 hdds Some Intel 2011 box w/ 2667v2s A custom AM5 server w/ 7700x, 8 hdds An old Cisco enterprise 48 port (&4 SFP+) switch It seems to hover ~800w.
I’m looking into replacing a lot of it especially the Intel server because it’s used for just pfSense.
My Grafana dashboard says 81 watts at the moment. This includes a slightly beefy Intel computer running Proxmox, with a Kubernetes cluster inside, a few other small ARM servers, and my networking stack which is a router, 1 switch, 1 AP, and a modem. Also the main server is full of spinning rust disks. I haven’t done much to optimize power consumption.
About 45W for my router, fiber endpoint, switch, three wireless APs and a Pi4 running Home Assistant. I've got a synology running separately that I suspect uses more, but I haven't measured it recently. Thinking about putting the synology in the crawlspace as it's kinda loud.
Out of curiosity, what whitebox are you using for the NAS? An old PC or something you assembled purposely for the NAS? Would love to see pics too as I’m considering going down this route.
I’ve purposely build that NAS around two or three years ago. It’s a Gigabyte B360M D3H mainboard, Intel Pentium Gold G5400 and 16GB of the cheapest RAM I could find. An Adaptec 71605 card provides SAS/SATA connections for up to 16 drives and a Mellanox Connect-X3 connects my NAS via 10Gbit/s to my network. The case is an Inter-Tech IPC 4U-4424 . It has 24 hot swap bays. But I would not recommend it because the backplane is terrible. Four or five slots are not working. Sometimes, when I re-insert a drive, it is not detected.
Using cheap RAM bit me in the ass last year as one of the RAM sticks started to fail. I didn’t notice that there is a problem with the RAM at first. Only when I observed that one of my scripts was not working I started to investigate the problem. Turns out that one of the RAM sticks failed. Re-inserting the stick did not resolve the problem so I replaced all sticks with old Crucial RAM I had laying around. Some files that I transfered to the NAS during that time period are corrupt. In the future I won’t use cheap RAM anymore and I’m also currently planning to replace the mainboard and CPU with something that supportes ECC RAM so that I can be notified when on of the sticks starts to fail.
Mine runs a little under 18 W with one 8 port managed switch, a DSL modem, CM4-based router, a tiny Wifi AP, and an Intel Celeron J4105 based mini PC server.
My rack looks to pull about 325-350W. I need to downgrade my main server, as it's a bit overkill as a decommed proliant. Need to figure out a high ram nuc as a replacement
