Abstract: The increase in the number of Data Centers, in recent years, generates an increasing consumption of energy, with a considerable impact on global energy consumption and effects on the environment. Efficient energy monitoring is the foundation of building a “green” data center. A energy model for servers is required to achieve energy management in data centers. This article presents and analyzes several server energy models, more often used for data centers. The variables involved in server energy models are the frequency and degree of processor usage, memory and hard disk usage, performance, temperature, and fan speed. Server energy models are mainly classified into additive models and active-base models. A comparative analysis of server energy models and their application error is performed. Experimentally, an analysis of energy consumption for different servers was performed.

Keywords: Data Center, server, energy models, additive models, active-base models.
