I wanted some backup in case the power went down at home, not that it happens every day or even month but it happens. there was always a problem after such an event, not all the discs were found on my opensolaris (usb disk with a very low spin up time) or it was stuck on the boot archive. So I bought me two of these UPS’es, each for about €80 and they have a usb cable to monitor them! I hooked one to my soekris downstairs wich runs openbsd and one to my backup/media server running opensolaris. here is what I did to configure them from the source on http://www.apcupsd.org/
