    Gurus,

    We are moving offices, and the construction company is bugging us about
    power and AC requirements for a new server room (we have 3 half full
    racks)

    We have looked at the servers, and e.g. an E450 has a maximum power usage
    of 13.6Amps (I would guess at 100V), and maximum heat output 5680 BTU/hr.

    However, how do I get these #'s down to a realistic #?

    Is there are some rule of thumb? If I calculate all maximum powers of all
    equipment I get something like 110Amps and 47000BTU/hr, which is highly
    unrealistic.

    If you can point to some docs on standards, that could help too.

    Thanks.
