Techniques to achieve energy proportionality in data centers: A survey

Abstract

A data center is a set of physical and possibly virtual machines along with other components such as storage, network, cooling, power supplies and management software, that function together to serve data and information to facilitate information services to a business or organization. It consists of computing and data dissemination as the main functions, however there are several other physical elements such as cooling management and power budgeting that interact with the computing elements, thusly making a data center to exhibit both a cyber and a physical behavior.
