[Beowulf] How to choose an UPS for a Beowulf cluster

I'm building a small Beowulf cluster for HPC (about 16 nodes) and I need
some advices on choosing the right UPS. The UPS should be able to signal
the central node when the battery reaches some level (I think this is
common usage) and it should be able to turn itself off before running
out of battery (I was told that this extends the life of the battery).
10 minutes of runtime sould be enough. I was looking in the APC site but
I was rather confused by all the models available. Can anyone give me
some advice on the type of device to choose?

Thanks for any tip
