October 16, 20187 yr Hey All, Build my new server a few days ago and i love the updates on UnRaid since I tried it a few years ago. The only thing that bothers me is the power usage, i chose low energy components, but bare install + power tweaks (tips & tricks, governor). still give me 10+ more watt than on another distro (Fedora/Debian). Most of this is actually caused by the usage of the package "Powertop" in the other distro's. Unfortunately this package is not available as plugin for UnRaid so I'm looking for other methods to save energy. I already looked into: - Auto sleep > Not exactly what i want, i can WoL when i need it, but when someone else from my family is trying to access the server they can't. - Governor > Set to powersave, but not the result i expected - Spin down times > I notice unraid saying the disks are spun down, but they're still rotating, only way to spin them all down is using the spin down all button in the main tab What other measurements can i take to save power? a tool like powertop edits a lot of settings and can get my config down to 12 watts idle/spun down. While atm it's at 30+, but those arent' available in Unraid.
October 16, 20187 yr Do you happen to know if the processor is down clocking? With 30 watts of consumption I'm assuming either a tiny processor or not a lot of disks. Could you give more insight into what hardware your using and amount of disks? Reason that is a "need to know" is there have been issues with downclocking on certain hardware.

When I read the post, fist thinking was even with 1 disk only, whole system really hard to idle in 12w. BTW, it is possible and I am not interesting / agure for 12w or 20w or whatover. 3 hours ago, wessel145 said: - Spin down times > I notice unraid saying the disks are spun down, but they're still rotating, only way to spin them all down is using the spin down all button in the main tab I just update to 6.6.2, this kind of bug seems come back, I will report it.

Imma replace my mobo and intel stock cooler for a fujitsu and passive one, that will save me a watt or 4 on top of it. I actually reinstalled everything (i did tests on another mobo) and that caused the power to drop. Still figuring out how that happened, but it's kinda the results I was hoping for in the first place (spin up idle = 24 watt) Over time i'll replace my 3,5" HDD's for 2,5". Since they use a lot less power.

I'm at 6.6.2 and i'm still having this bug, Unraid is telling me the HDD is spun down, when i log into console and check with "hdparm -C /dev/sdx" it's still active. I guess that has a lot to do with the initial power issue i'm having

I guess that has a lot to do with the initial power issue i'm having I have Brennenstuhl too (PM230). Pls note those device ( in fact many other device ) couldn't accuracy do power measurement. The "bug" I also report, but truly said, most time Unraid could spindown disk as expect.
