I have a HP Proliant DL380G7, basically the last server with a front side bus, and all the comments about it where about power per watt.
and they’re not wrong.
I just don’t think this is the community for old servers like this, self hosting is very much a practical consideration and the money spent on electricity running anything useful on these old things is better spent on a raspberry pi or stand alone NAS or something.
just messing around on https://shell.cloud.google.com is good for a beginner to unix enviroments.
my scsi controller needs to be entered during boot to manage raid. it also has an external battery that needed replacing (which cost more new than just buying a new card … with the exact same battery) so if you’re not in verbose boot mode figure that out and see if the controller is telling you which function key it needs.
figuring out this old stuff is most of the fun in running it, I would sell it as scrap before actually hosting anything on it.
