What is PUE and why should my company know it’s PUE?

Power GeneratorPUE stands for Power Usage Effectiveness. Knowing your PUE gives your company a baseline of how efficient their data center is and helps to set a goal of where and how efficient you want your data center to be. PUE is a measure of your Total Facility Power divided by the Total IT equipment power. This gives a number to show your current efficiency. The lower the number the more efficient your data center is. A PUE of 1 is virtually impossible but is theoretically when all power in the data center is used to power the IT equipment which is optimum efficiency. A PUE of 1.6 is an Optimized data center and is feasible when taking appropriate measures. A PUE of 2 is an efficient data center and is a good first target. A PUE of 2.4 is an average data center and more improvement may be needed. And finally a PUE of 3 or greater is inefficient leaving a lot of room for improvement.
