Ways to reduce data center electrical cost are a top priority for many IT executives. A new white paper from APC explores models for estimating electrical losses as a first step in finding ways to reduce data center electrical cost.
APC White Paper on Electrical Efficiency Modeling
Conventional models for estimating electrical efficiency of data centers are grossly inaccurate for real-world installations. Estimates of electrical losses are typically made by summing the inefficiencies of various electrical devices, such as power and cooling equipment. This paper shows that the values commonly used for estimating equipment inefficiency are quite inaccurate. A simple, more accurate efficiency model is described that provides a rational basis to identify and quantify waste in power and cooling equipment.
