I need to spec a UPS for a Dell PowerEdge T320 running Hyper-V and an SBS 2011 Std VM:
It would need to cover the server for say, 30 - 45 mins (obviously longer is better), plus a screen and KVM switch (USB keyboard and mouse).
Perfect world, it would also cover a VDSL (soon to be fibre) modem / router.
Even better if it could also handle another physical 'server', which is actually a Dell Optiplex PC running a LoB application.
The T320 also has a 2.5" external USB Drive plugged in (backups) and the Optiplex has an external 3.5" USB drive (backups). Backups themselves run within about 30 mins, hence aiming for 30 - 45 mins battery time seems to make sense.
I had thought about something like this:
but I don't have much experience with UPS so looking for a recommendation / sanity check.
