PFE1100-12-054NA White Paper Issue 6
Power Savings in the Data Center.
Data center PUE for this example is set at 1.9 (refer to Table 9 for EPA 2011 target details), with the cost of
electricity at 11 cents per kWh. Calculations refer to the full set of 10 upgraded racks (de?ned on page 13) to
run with the PFE1100-12-054NA.
Data centers take steps to maximize ef?ciency in the application of fans, chillers, UPS, PDU’s , etc.
Sometimes selecting the best hardware can provide better energy, carbon and cost savings. The mechanical
cooling systems are left to remove the heat from a data center. The Coef?cient of Performance (CoP) de?nes
the ef?ciency of these criteria. If it takes 400 W to remove 1000 W of heat, then the CoP is 0.4 or 40%.
A data center has to allocate the worst case power draw from a rack of servers. From the IT load a facility
load is calculated, this changes relative to the PUE.
High ef?ciency server power supplies will reduce the IT load, also then reducing the facility and assisting
with the other infrastructure changes throughout the ongoing process of PUE reduction.

Taking the example from Table 7 and applying a 100 rack data center example would provide the following
data shown in Table 10.
