I use APC, because the explicitly support Linux, even
providing the Linux version of their powerchute program
on their website.

Right now I'm considering a new UPS. I used MGE (a sponsor

My question : do you protect more than one server with one UPS?

That depends on your circumstances.
What's the capacity of your UPS
What's the power draw of your servers?
How long does it take a server to shut down?
In light of the power draw, how much of the UPS battery
will you use up if you shut down immediately when a power
outage is connected?

How much spare time is left over -- so that you can set
the program to WAIT for, hopefully, at least 60 seconds
before starting an automatic shutdown.

I'm not sure..it's been 3+ years since I played with it.
And since I've beeen on a laptop for the last year and
a half... I haven't even thought about it.

I'm going to be rebuilding the tower soon...but not
right now (I have other priorities at the moment).

to the UPS's status, "slaves" just get power from the UPS.
Can Windows be part of this setup ?

If not, you can just create a shell script that shuts
down the slave machines if powerchute starts to shut
down the master.

I looked on their web-site but I didn't find these answers, maybe I overlooked?

Download the ...I think it's a tarball(?) and then
read the README.
