Don't forget that with a bigger/more expensive UPS, most of the time you have the advantage of hot-swappable battery's and/or a bypass function plus the ability to shut down more than one server if things go wrong. Most of the small UPS's have to be shut-down to swap the battery's. Furthermore with the big UPS's the battery voltage is higher resulting in low amp's on the battery's resulting in longer lifetime.
Erland, I think you're talking very large UPS'es here - I haven't seen anything less than 25kVA with hot-swappable batteries. Bypass mode yes, but hot-swappable batteries is another level. /Per -- /Per Jessen, Zürich -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
