I have a system running with my old PC with a few HDD and SSDs. The system uses about 40 - 50 WATT currently that sums up with the german power supply costs over time.
Currently, i use unraid as a NAS from time to time, so i don't need the system for days at all.
Is there a setting or a docking container or anything that powers the system down to a minimum when in idle and powers the system up, when it is required like access a share or the scheduler starts to calculate parity or whatever happens?
So there is a little delay until the required data is available but that would be fine.
It would be good to save some power when the system is not required.
