I have few machines and am wondering when to start bothering with upgrades. Power is not too expensive here so I would probably switch if I can halve the idle wattage whenever more recent used hardware hits the second hand market.
I am currently looking at 70-90W per server.
NAS server has 4 disks 1 ram stick, proxmox has 8 disks full ram.
Alternatively, do I ride with the current setup until they fall apart?
I did a BIOS power tune recently, and that shaved off 14 watts on idle.
So that’s a thing you can also do.
