Data Center Levels and Tiers

Data Center Levels and Tiers are dedicated spaces that are used to house computer systems and their parts. Additional duplicated or backup data parts, telecommunication, and security-based equipment. As well as the fundamental infrastructure and facilities for power supply. The dedicated area designated for the data center may be located inside one building or a group of buildings.

Data Center Levels and Tiers are a framework for uniformly describing particular types of data center tiers infrastructure. Tier 1 infrastructure is the most basic, whereas Tier 4 infrastructure is the most intricate and has the most redundant parts. Each layer has all of the necessary elements from the tiers below it.

Data Center Background

Data Center Levels and Tiers were first observed in the 1940s, during the work of English mathematician and computer scientist Alan Turing. Who developed ENIAC (Electronic Numerical Integrator and Computer). The first original electronic general-purpose digital computer, and introduced the idea of the organized structure of data-manipulation principles or procedures, known as Turing-complete.

When computers were first invented in the 1940s. They were incredibly large and required large rooms for storage and operation. The opportunity to install servers using hierarchically designed, meticulously detailed rooms within the organization or corporation was made possible during the 1980s and 1990s thanks to the ease of use of inexpensive networking-based devices or equipment.

Which are together with the original set of principles in the case of the network structured cabling in the building. This also gave rise to the term ” Data Center Levels and Tiers”, which started to gain widespread acceptance and identity.

Tiers and Levels of Data Centres

The Data Center Levels and Tiers policies and guidelines are created and published in the United States by the Telecommunications Industry Association (TIA) and the Uptime Institute.

Telecommunications Industry Association: It consists of Level 1 and Level 4.

Uptime Institute (Datacenter 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)
