Anyone else using a Xeon E5-2680 v4 (or similar?) - I have questions RE: power consumption (alien.top)

Hi folks,

I currently have a HP ML10v2 with Xeon E3-1265L v3 in it (4c/8t) and 16GB DDR3 ECC. At work, we disposed of (and I now have in my wardrobe) a dual socket Xeon E5-2680 v4 (14c/28t each) and 64GB DDR4 ECC RAM.

Now this is obviously a massive jump in horsepower, and I very much doubt that I have any use case for a total of 28c/56t, so I was considering removing one of the Xeons and keeping it spare. I currently use a 1050TI for transcodes and that will be moved across.

It's all built on a ASUS Z10PE-D8 WS motherboard, so I'm just looking for anyone else using similar gear, and any tips you might have to reduce power consumption. I haven't yet gone diving through the BIOS to see what options are there, but I'm hedging between trying to screw down the power consumption, and just seeing if I can sell off the bigger machine and get a more modern Core i5 or similar...

As is, on the HP I'm running Unraid with a dozen docker containers, and that's about it. I would like to start playing with Ansible, so the bigger system would be good in that regard, but I'm not 100% sure if I want to keep this machine or not.

For reference, my power costs are AUD $0.8087/day supply charge, and AUD $0.2299/kwh. I'm renting so have no options for solar etc.

Thanks!

I have two 2680v4 with 160GB of RAM, 1 SSD, and 12 HDDs (4 SAS, 8 SATA), and a Quaddro P5000. Average consumption over the last week is 220W (about 25 docker containers that run plex-related stuff 24/7, and a handful of self hosted things). Min consumption (roughly idle, I assume) is 164W. Power is cheap where I live, <12¢ per kWh.

You could cut power consumption down by removing a CPU or consolidating your storage to fewer drives (or going with SSDs if thats in the budget).
