Data Centre (Telecom)


Data centres are relatively new features on the UK’s urban landscape. In fact, many people are unaware that they even exist. Often occupying boring-looking industrial buildings or nondescript offices, data centres take the form of rooms or halls packed full of computing equipment, patrolled by small numbers of geeky looking individuals who talk in a language only vaguely related to English. Nobody seems to understand why they are there or what they actually do, which in most cases appears to be shrouded in secrecy. Yet data centres underpin an incredible range of activities across government, business and society and are now part of our critical national infrastructure whether we like it or not. So it seems worth finding out a bit more about them. This document explains in simple terms what data centres are, what they do and why they exist. A data centre is a building (or self-contained unit within a building) used to house computing equipment such as servers along with associated components such as telecommunications, network and storage systems. A data centre is equipped with a guaranteed power supply and high bandwidth connectivity. Resilience is critical so redundancy (duplication) of networks, power and other infrastructure is common to ensure continuity. Other facilities include building management controls such as air conditioning to maintain the environmental conditions for the equipment within a specified envelope of temperature and humidity, and security systems to ensure that the facility and its data remain secure
