Estimated Power Cost Comparison of Physical Server Vs Virtualized Server in a Data Center

Abstract

The Cloud computing environment provides computing resources on-demand and based on pay as needed. Different organizations (mostly IT) store confidential data in cloud storage systems and in a manner such that only authorized clients can access the data. Therefore, a data center plays a key role in this setup. The more efficient a computing resource technology is, the less will be the load on an existing data center. In this regard, opting for virtualization of a data center can prove to be power saving as well as cost saving. In a virtualized data center, systems are partitioned to offload pressure on energy consumption. The resulting energy savings can be further accelerated through proper adjustment of power and the use of appropriate cooling infrastructure. Currently, the high rate of growth of IT departments is generating huge amounts of data on a day to day basis. As such, virtualization will be extremely helpful for storing and accessing data properly at minimized cost and low energy requirements. This paper is a review of the savings that can be achieved in terms of power consumed by a virtualized server in the data center environment.
