PUE: Core Metric for Data Center Energy Efficiency

What is PUE

PUE (Power Usage Effectiveness) is the most commonly used metric for measuring data center energy efficiency.

Factors Affecting PUE

Main factors affecting PUE include cooling system efficiency, power supply system efficiency, and lighting and auxiliary equipment energy consumption.

Methods to Optimize PUE

Common measures to reduce PUE include natural cooling, optimizing airflow, introducing liquid cooling, and improving power supply efficiency.

• Traditional data center PUE is usually between 1.5-2.0,Advanced data center PUE can be controlled below 1.3,Liquid cooling technology can reduce PUE below 1.1,PUE monitoring requires multi-dimensional data on IT equipment, cooling, and power
