A data center is a facility used to house computer systems and associated components, such as telecommunications and storage systems. It generally includes redundant or backup power supplies, redundant data communications connections, environmental controls (e.g., air conditioning, fire suppression) and various security devices. Large data centers are industrial scale operations using as much electricity as a small town.

Another definition could be, a large group of networked computer servers typically used by organizations for the remote storage, processing, or distribution of large amounts of data.


With the rapid growth of the Internet economy and the explosion of information technology, the data center is playing a pivotal role and is one of the most exciting fields in the world of IT today. The trend continues with both virtualization and cloud computing fueling growth and making data center solutions more efficient and scalable. More specifically, organizations using virtualization technologies are seeing greater returns and more viability to deal with the growing demands of the economy.


Data center virtualization is an evolutionary process that was started several years ago within mainframe computer rooms, and it has dramatically intensified in the last few years. Its proposed freedom from physical boundaries has produced benefits in each technology area, and much more importantly, from an architectural perspective.
