![]() ![]() 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. 1962ĭata centers have their roots in the huge computer rooms of the 1940s, typified by ENIAC, one of the earliest examples of a data center. History NASA mission control computer room c. Four common categories used to segment types of data centers are onsite data centers, colocation facilities, hyperscale data centers, and edge data centers. ĭata centers can vary widely in terms of size, power requirements, redundancy, and overall structure. This excludes energy used for cryptocurrency mining, which was estimated to be around 110 TWh in 2022, or another 0.4% of global electricity demand. Estimated global data center electricity consumption in 2022 was 240-340 TWh, or roughly 1-1.3% of global electricity demand. A large data center is an industrial-scale operation using as much electricity as a small town. Since IT operations are crucial for business continuity, it generally includes redundant or backup components and infrastructure for power supply, data communication connections, environmental controls (e.g., air conditioning, fire suppression), and various security devices. ![]() Building or room used to house computer servers and related equipmentĪ data center ( American English) or data centre ( Commonwealth English) is a building, a dedicated space within a building, or a group of buildings used to house computer systems and associated components, such as telecommunications and storage systems. ![]()
