I've got several Compaq servers with dual power supplies which I'm going to split across 2 different power sources.
I am trying to determine the amount of power required for these servers so I don't overload my UPS and/or the electrical circuits.
Since the electrician here talks about the circuit load in terms of amps, that's how I've been trying to rate the load that the servers will need.
The power rating on the back of the server has 2 numbers for amps (e.g., 7.6 and 3.8)--I'm assuming that the 2 numbers represent the amperage at 120 volts and 240 volts. What I need to determine...
(1) At 120 volts, is the 7.6 amps the total load that the server pulls or the load per power supply?
(2) When both power supplies are operational, is each one pulling half of the amp load or is 1 power supply the master and pulls the full load?
(3) At 120 volts, is 7.6 amps the peak load that will be pulled? It seems that I've read somewhere that equipmdnt typically pulls more power during a power on cycle. Is this 7.6 amp rating the most that the server will ever pull? If so, what's a ballpark pct for what it requires during normal operation?
Thanks!
