Power efficiency (lemmy.zip)

I'm wondering what folks do to optimise the power efficiency of their Linux servers. I've never really got to the bottom of what is the best way to do this and with the current energy crisis its a pertinent topic.

I'm talking about home servers, so the availability requirements are not the same as in a corporate environment. There might be vast chunks of time during the day or night when they sit idle, and home users are more tolerant of a lag when accessing resources if it means lower energy bills.

Specifically I've been thinking about:

allowing lower power states when idle
spinning-down hdd's when they're not in use
MAYBE letting machines sleep/hibernate
setting schedules of times where you know demand will be low/zero and efficiency can be managed aggressively
any other quick wins I've missed

It would be amazing if there was one tool or one guide that helps with all of that but thats never the case, is it 😅

Thoughts?

I had to start over anyways, so I choose SSD only. Pricier of course, but I don't need a terrible lot of space anyways.

When I still had HDDs, they were usually used once a day for backups, and I spun them down after that.

Optimizing power profiles and C states makes a little difference, but planning with efficient hardware from the beginning is the most important thing. Don't use your old gaming PC if you care for power efficiency.
