Flight Simulator Calculation - running costs

Simulator Calculations
We assume ~12 racks (but power below is probably for 6 - 12 HPC racks depending on load)
P = IV [power = amps x volts]
rack = 30A x ~240V [note: some racks might use two 30A]
rack = 7200
E(kWh/day) = P(W) × t(h/day) / 1000(W/kW)
Energy per rack per day = 7200 x 24 / 1000
rack = 172.8 kWh/day
At 14p per kWh (Google today ;)
Cost = 172.8 * 0.14
£24.19
Assuming 12 racks, £290.30
Cost per year = 365 * 290 = £105,960.96
Bargain ;)
