WhiteNoseThunderPants Posted August 28, 2019 Share Posted August 28, 2019 (edited) So I have a Dell PE R710 that I am using for UNRAID, but it is definitely power hungry. It has been a very long time since I custom built anything (2001), so I need some advice. The server is performing great, but I need to reduce the power use. At the time of typing this, the idrac is reading 252W. Is this just what I need to expect on power usage or can I decrease this a good amount with a modern build that won't break the bank? Is my best option to just remove what I don't need as far as like a CPU and some RAM? Here are the specs of the R710: Dual Xeon E5645's 128GB RAM 1 x 500GB Edge SSD plugged into DVD connection as a cache drive 6 x 4TB WD Green 5400 RPM internal 3 x 4TB WD Green 5400 RPM in a Mediasonic box 1 x 4TB Seagate 7200 RPM in the same Mediasonic box 1 x 7 port USB3 card with 2 500GB SSD in external enclosures as unassigned drives 1 x 2 port esata card (Mediasonic box plugged in here) 4 x GBe ports in a bond group Here is what I am running on it: Docker Containers: plex deluge w/vpn nzbget w/vpn radarr sonarr tautulli jackett pi-hole grafana influxdb telegraf varken apcupsd-influxdb-exporter VM's: Windows 10 VM for Blue Iris (Will be moving this off to it's own machine) 8 cores & 8GB of RAM Ubuntu 19.04 VM for Hass.io (Possibly moving this to a RPi4 once it works properly) 2 Cores & 4GB of RAM Edited August 28, 2019 by WhiteNoseThunderPants Quote Link to comment
Vr2Io Posted August 28, 2019 Share Posted August 28, 2019 (edited) I would expect not much would save due to E5645 was 80w TDP only. People always think will save a lot if change to a 65w CPU. The reason was those 15w different was CPU only and talking in heavy load. This still in small ratio if compare to whole system power usage. I notice you have 2 USB mediasonic box, this also a factor for high power usage and UPS power reading just is a ref. and not always accuracy. Unless electric bill show save a lot, otherwise not much meaning. Edited August 28, 2019 by Benson Quote Link to comment
WhiteNoseThunderPants Posted August 28, 2019 Author Share Posted August 28, 2019 Actually I only have one mediasonic box connected via esata. The drives listed are in the same box. I see now how it could be confusing. and seem like two. So if I was to remove one of the processors, I would only save that 80w if the processor was always pegged at 100%, correct? If it is idle most of the time, I won't save much power by removing it. Quote Link to comment

Vr2Io Posted August 28, 2019 Share Posted August 28, 2019 If you remove one CPU, appreciate if you could feedback the founding here, thanks. Quote Link to comment
