As the importance of data centres grows, so too does the need for high-quality networks in order for the demands of the digital economy to be met. The modern data centre relies on quick and efficient exchanges of information, to and from customers and between the active IT components it houses. As such, growth in the deployment of virtualization and of cloud systems within the data centre mean that low latency, adequate bandwidth, connections and ports are as important as the adequate provision of power and cooling. The need for proper decision making and management in relation to network equipment, including cabling, is driven by data centre perational requirements. As with the equipment it connects, cabling should be modular, scalable and easily adaptable. It is able to transmit more data, faster and more accurately without an equivalent increase in the power or space required to do so. Improved design and management practices mean less time and labour are spent maintaining, repairing or installing cabling. More than ever, planning, installing and maintaining network cabling to standards of best practice gives operators a greater chance of chaos avoidance in the data centre.
