I have an HP Gen8 server running my home-assistant instance, and various other services (download, AI, etc) - I also have an 8 bay NAS - the combination chews through electricity, about 6-7kWh a day. (the heaviest user in the house - it uses double the heatpump)
I like the Gen8 because iLo - its saved me few times where I've been away and something brings the server down - I can remotely connect and bring it back up. I'd ideally like to keep it because of that.
I suspect the bigger power draw is from the NAS - its always on because I keep all the db's, HA logs, security snapshots, etc on it instead of the Gen8s SSD.
Any suggestions on getting power usage down? Thought of adding a 2-4TB 3.5" drive directly to the server and moving all my fast read/write to that - allowing the NAS to sleep when not being used. (streaming, backups, etc)
