Abstract: Energy demand in data centre industry is growing rapidly as computing technology changes and Information Technology (IT) professionals seek to maximise performance of data centres. A multitude of methods have been used to estimate and quantify energy intensity. Rising energy costs, continuing concerns about global economic downturn and global warming effects has leaded ways for energy efficient data centres. The goal of computer system design has been shifted to power and energy efficiency. This paper highlights strategies and techniques that provide energy savings in data centre like reducing frequent hardware purchases, power/cooling cost reductions, green metrics, shrinking data storage, workload consolidation and reducing physical servers.

Keywords: green data centres; green IT; information technology; energy efficiency; global warming; virtualisation; metrics; energy savings; energy consumption.
