What is the pue?

The term "PUE" stands for Power Usage Effectiveness, a metric used to evaluate the energy efficiency of a data center. It is calculated by dividing the total building energy consumption by the energy used solely for IT equipment. A lower PUE indicates better efficiency, as it means less energy is being wasted on non-IT infrastructure like cooling and power systems. The ideal PUE target often aimed for is around 1.1 to 1.2.
