These were called ' servers', as timesharing operating systems like Unix rely heavily on the client-server model to facilitate sharing unique resources between multiple users. The advent of Unix from the early 1970s led to the subsequent proliferation of freely available Linux-compatible PC operating-systems during the 1990s. However, as information technology (IT) operations started to grow in complexity, organizations grew aware of the need to control IT resources.

Basic design-guidelines for controlling access to the computer room were therefore devised.ĭuring the boom of the microcomputer industry, and especially during the 1980s, users started to deploy computers everywhere, in many cases with little or no care about operating requirements.

Security became important – computers were expensive, and were often used for military purposes. A single mainframe required a great deal of power, and had to be cooled to avoid overheating. Many cables were necessary to connect all the components, and methods to accommodate and organize these were devised, such as standard racks to mount equipment, raised floors, and cable trays (installed overhead or under the elevated floor). Early computer systems, complex to operate and maintain, required a special environment in which to operate. Historyĭata centers have their roots in the huge computer rooms of the early ages of the computing industry. Large data centers are industrial scale operations using as much electricity as a small town. It generally includes redundant or backup power supplies, redundant data communications connections, environmental controls (e.g., air conditioning, fire suppression) and various security devices.

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