Good to hear that you got things going. As for the dual supply servers on
two ups units, this is what lead me to use Nut in the first place. The docs
discuss this setup:
The main thing you need to make sure of is that your server does not freak
when it looses power on one unit. We had some ML370 Compaq servers that
would boot and run on one supply but if the server booted with all three
supplies (yes three) plugged in and the one plug was pulled the server would
shut off. Our dual unit servers seem to be fine loosing one supply (DL380)
as I have moved the servers between UPS units by moving one plug at a time.
In my scenario I used one server (actually a virtual server) to monitor all
20+ UPS units and then let the servers talk to it for status.
