Data Centres are at the core of Corporate and Internet businesses and are the foundation blocks of the world economy. Data Centres range in size from small rooms in SME businesses supporting their own operations to purpose built campuses of hangar size buildings with multiple halls supporting the world wide web and global corporations. The IT facilities themselves are secure, robust and reliable providing a stable environment for the equipment and to minimise downtime. Regardless of whom owns the information shared, whether it is government, industry or the general public, there are common demands, most importantly, instant access to current and accurate data on demand and without disruption, 24 hours a day, 7 days a week, 365 days a year. Data Centres reliably store data and applications for remote access by users. The increasing volumes of data held and the growth in demand to access the data, means Data Centres need a high speed, scaleable and flexible IT infrastructure. The complex issues impacting Data Centre operational efficiency must be addressed in all aspects of design to achieve optimum performance and improve return on investment. Ultimate service reliability is essential as downtime costs money, and new technologies must be embraced to maximise network performance, availability and business continuity. The tiering of a Data Centre influences the cabling infrastructure design. A Tier IV installation requires IT cabling to be dual routed to support the availability target. The components employed in the cabling system must be designed for optimum performance over their installed life and meet the rigours of the environment. This not only requires assured component reliability but also intelligent cable management, secure routing and management at distributors and equipment outlets.
