Data Center

A data center is a facility used to house computer systems and associated components, such as telecommunications and storage systems.

The server room or system, also called a communications room, houses the server and the data warehouse..

Data centers are generally divided into two categories: private data centers and Internet data centers. Private data centers are used by one organization only. The Internet data centers provide services to third parties. The electrical, mechanical, and security systems vary according to the processed and stored in DC data and its significance. Data centers are generally supposed to have redundant power supplies, redundant data communications connections, air conditioning systems used for cooling of systems located in the center, fire fighting systems and the protection against the dangers that may come from outside; they keep their security systems according to the data and the degree of its security.

The data center roots in the history of the computer room in the early era of the computer industry. Operation and maintenance of the first computer systems such as Data Centers were quite difficult and needed a special environment to work. The first computer networks were created by a combination of a large number of equipment via a cable connection. Interconnection of an equipment plurality necessitated a variety of procedures and methods. For example, standard data center rack is mounted on the equipment which uses raised floors and cable trays as in the first computer system. Security was very important because quite expensive computers were used for military purposes. With critical data centers, authorization was required to enter the computer room. In the period of development of the microprocessor industry, especially in the 1980s, computers began to appear everywhere, but in most cases the operating requirements were ignored. However, with the improving of the information technology operation and its complexity companies have realized the necessity of information resources management. Client-server models of microprocessors (now called servers) began to take their place in the old computer room in the 1990s with the development of network architecture. To make network equipment accessible in prices, new standards for structured cable networks were defined; it enabled the creation of a hierarchy of servers put into a special room in the workplace. The specially designed computer room was named ‘a data center’ and the term is widely used today.
