![]() PUE is not the only focus for the measurement of data center efficiency Saving energy is a sustainable task and if enterprises can combine a PUE value with the cycle of measurement, analysis, planning and action, even high-density data centers with high power usage can achieve continuous power savings. The goal for the Green Grid’s PUE is to provide a metric that can be used repeatedly. ![]() A lower PUE value means a higher energy savings. The Green Grid provides a formula to calculate the PUE value and determine the power usage status-simply divide the total power of the data center by the power used for IT, or divide the total facility power by the IT equipment power. The Power Usage Effectiveness (PUE) promoted by The Green Grid, an association of IT professionals, is a standard international index used to assess power usage efficiency. ![]() For high-density data centers, the green issue is equally important. With the gradual depletion of global energy, enterprises face the unchangeable fact of higher and higher energy costs. ![]()
