Upgrading an old, inefficient data centre cooling system can result in a 50 per cent reduction of cooling costs. • Reduce unnecessary airflow and cooling. power use and supply • Minimise lighting levels, and install sensors. • Reduce unnecessary power consumption by removing idle resources, improving management practices and implementing systematic checking. • Replace and update old equipment. it function, data storage and application • Remove duplicate data (de- duplication) to consolidate storage requirements and decommission old servers that are no longer required. • Apply virtualisation software for control of server activity and to maximise utilisation. Seek advice from IT staff to ensure that ICT equipment runs under optimal conditions, and to prevent equipment failure.

Consider outsourcing to an off- site data centre, or procuring it as a service Outsourcing your IT to a service provider, or using cloud computing for some or all systems, is becoming increasingly popular. Specialist providers and facilities have economies of scale and are generally leaders in best practice. They will most likely be running shared servers at optimal conditions, which should be more economical and energy-efficient.
