This course, held over three days, is aimed at teaching best practice design principles for the design, construction and operation of computer rooms and data centers. It consists of a number of subsections that address the fundamental requirements of a successful design such as electrical power supply, air conditioning, airflow management and data cabling. Best practice is achieved by bringing together the requirements of Building Regulations, Statutory Instruments, and E.U. Directives, British, European and International standards. Several case studies are considered to see examples of good and bad practice in real situations. The unit is principally assessed by an ongoing design exercise that leads the delegates through all the steps needed to arrive at a baseline design of a modern data Centre. All the Data Centre Courses have been fully updated to take into account the requirements of the 2009 EU Code of Conduct on Data Centers Energy Efficiency.

To understand the best practice of design principles, construction, operation and ongoing management of computer rooms and data Centre’s Ensuring they are efficient and compliant.

Prerequisites

• Experience of the data Centre environment is essential.
