What is PUE and how is it calculated?
PUE (Power Usage Effectiveness) is a metric used to identify how efficiently your data center is running. By comparing total facility power to your IT power, a ratio of cooling vs IT power is calculated. The lower your PUE the more efficient your data center. But it doesn’t tell the whole picture. A low PUE can be achieved by adjusting your cooling setpoint or turning off servers. But this doesn’t mean you are operating efficiently. Underutilized server capacity or undercooling does not make for an efficient data center operation.

This calculator gives you a benchmark from two figures. Your actual PUE moves with cooling setpoints, airflow, containment, and load — finding out where it's drifting takes measured data, not estimates.
