Data center is a committed space, which is used for the purpose of storing computer systems and its components, additional duplicated or backup data components, telecommunication, and security-based devices, basic structure and facilities in case of power supply, etc. The committed space allocated for the data center can possibly be inside a building, or in a set of buildings.

Data Center History

  • The first time data centers came into sight in the 1940s, during the time of the English mathematician and computer scientist, Alan Turing, who gave the concept of the organized structure of data-manipulation principles or procedures, known as Turing-complete through ENIAC (Electronic Numerical Integrator and Computer), the foremost original electronic general-purpose digital computer.
  • In the 1940s, in those times the computer sizes were very big, which covers huge dimension based rooms for the purpose of functioning and storage.
  • During the 1980s and 90s, the effortlessness in the use of reasonably priced networking based devices or equipment, which are together with the original set of principles in case of the network structured cabling in the building, created the prospect to put down servers by the use of the hierarchical designed precise detailed rooms within the organization or corporation, which also gave life to the term 'data center' that began to put on well-accepted appreciation and identification throughout this duration of the era.

Data center levels and tiers

The Telecommunications Industry Association (TIA) and the Uptime Institute brings out the data center policies and guidelines by preparing and issuing the policies and guidelines in the United States.

  • Telecommunications Industry Association: It consists of Level 1and Level 4.
  • Uptime Institute (Data center Tier Classification Standard): It consists of four Tiers, which are:
    1. Tier I (BASIC CAPACITY)
    2. Tier II (REDUNDANT CAPACITY)
    3. Tier III (CONCURRENTLY MAINTAINABLE)
    4. Tier IV (FAULT TOLERANT)
