Probably correct, I bought some power meters from Maplin, and tried it 
on the dual processor Compaq DL360 (2 x p3'S, 2 X scsi) idling in the 
rack with little disk activity chews 0.39A or about 80 watts. I'll try a 
meter on a DL380 later.

My DL380's at the DC are at least partitioned into 10 VPS's however I 
would not go as far as to say they are doing the job of 10 hardware 
servers :/
