UPS/Power Sizing - Data Center Racks

[paul2006]

Hi - am looking for a bit of advice on something that I've never done before regarding UPS

I have a couple of specific questions:

1. For a given UPS (E.g. APC3000) - how do I work out what power feed it requires (i.e. in Amps) - is there a rating or calculation that can be performed to provide this value

2. With my UPS (Again assuming a APC3000) how do I work out how many servers it can take before it becomes full - supposing for example I was using HP DL servers - again is there a rating or calculation I Can perform from the standard details the manufacturers provide!

If anyone can answer these two questions, it'd really help plug a hole in my knowledge

Thanks
paul

There's a load calculator depending on your config (ie processors, power supplies, HD...) on APC's website at
