PFE1100-12-054NA White Paper Issue 6
Energy Savings Using PFE1100-12-054NA
The following section details the energy effects using the PFE1100-12-054NA in a data center environment.
Table 5 detailed the server count for key companies. A rack of servers using 1100 W power supplies would
not be a typical x86 server; the power in these servers is more typically between 450 W to 850 W
This paper will demonstrate how much energy and carbon emissions are reduced in a single-rack
con?guration and a 10-rack con?guration, with both examples using the PFE power supply.
This example details systems requiring 1U redundant 1100 W front ends. The system power budget for this
example is set at 850 W maximum per server and the rack contains 40 x 1U servers.
Data center PUE for this example is set at 1.9, (de?ned as current trend by the EPA as shown in Table 4), with
the cost of electricity at 11 cents per kWh. Workload for each server has been set as a variable load
between 20% and 50% load of a single 1100 W supply, with the load shared 50:50 by the redundant PSU.
Power and climate comparison data is shown for each product across the Climate Saver speci?cations,
Silver, Gold, Platinum, and PFE1100-12-054NA. The baseline for all calculations is the Silver requirement as
de?ned in Table 6.
