Industry needs to benchmark data centers<br />
Efficient components are necessary, but not sufficient<br />
<strong>HP</strong> introduces “Power Usage Effectiveness” (PUE) for the data<br />
center<br />
• Look at the ratio of building load to IT load as a measure of efficiency<br />
PUE = Building Load / IT Load<br />
Industry numbers suggest<br />
PUE = 1.6 Ideal 0%<br />
PUE = 2.0 Target 5%<br />
PUE = 2.4 Ave 10%<br />
PUE = +3.0 Poor 85%<br />
Building load<br />
Demand from grid<br />
Power (Switch Gear,<br />
UPS, Battery<br />
backup, and so on)<br />
Cooling (Chillers,<br />
CRACs, and so on)<br />
IT load<br />
Demand from<br />
servers, storage,<br />
telco equipment, and<br />
so on<br />
