What is a data center?

How many of you have wondered about a data center? Have you ever got a clear picture of what is a data center? This article will give you an exact idea about the complete building architecture of a data center.

A data center is a facility that houses an organization’s IT operations and equipment’s in the most effective and secure manner. Technically speaking, it is composed of a number of elements such as routers, switches, security devices, storage systems, servers and more. These are the components that IT needs to store and manage the most critical systems that are vital to the continuous operations of a company. Because of this, the reliability, efficiency, security and constant evolution of a data center are typically a top priority.

They have existed in one form or another since the advent of computers. The main pillars of a data center facility can be classified as SpacePowerCooling, and Connectivity. The operation of a data center will be related to or depend on these four constraints. Each of these constraints are larger than you think and more details will be discussed in the coming articles. 

An overview of data centers building can be as below,

Data Center Building Architecture

This picture is as simple as possible to show the building structure that a data center consists of. However please note that some of these facilities will differ based on the standard/certifications that each data center follows.


Typically a data center building will have all building facilities as per the local law with the addition of below areas,

Building Area Function
Computer room/server room House computer racks and communications equipment
Control room/Network Operations Control(NOC) All control and monitoring functions are concentrated
General office area Works space for Computer/Electrical and Mechanical engineers
Entrance facility/meet-me room/point of demarcation Where external communications cabling enter the building
Fire gas suppression storage room Space depends on the type of gas used
 Electrical switch room Electrical power cables enter the building and form a demarcation point
UPS in the battery room Recommend: For loads of 100 kVA and above to have a separate UPS room
Generator room Houses standby diesel generators
Fuel oil storage Houses diesel fuel for generators
Storage and build area/staging or provisioning room To store and unpack, prepare and build equipment 
Delivery and loading area The adjacent area to allow heavy equipment to be shipped into the building
Planning and meeting room To hold meetings
Internal staff facilities Male/female/disabled toilets and showers
Electrical substation Due to power needs, a separate substation may be required
Air conditioning condensers A secure area is required depending on the air conditioning requirements
External staff facilities Parking spaces

Also, I would like to make your attention to the definition of a data center as below based on certain standards like TIA(Telecommunications Industry Association) and EU(European Union).

TIA 942 states that a DC is “A building or portion of a building whose primary function is to house a computer room and its support areas”

EU Code of Conduct states that “All buildings, facilities and rooms which contain enterprise servers, server communication equipment, cooling equipment power equipment, and provide some form of data service”

Data Centre Functional Requirements

Have you ever thought of a requirement for having a data center? What is the function of a data center? Answers are as simple as below,

  • To locate servers, storage and networking devices safely and securely
  • To provide the power needed to maintain these devices
  • To provide a temperature-controlled environment within set parameters needed to run these devices
  • To provide connectivity to other devices both inside and outside of the data center
  • To provide other services that may be required to support these devices.

I hope things are clear to you. Would you like to know what are the types of data centers that we use? Look at this article to get more ideas about this.
