Data Centre Design

Course Supplier: CNET Telephone Number: 0121 326 2219 Cost: £1,095

Description:
­

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 centres.

It consists of a number of subsections that address the fundamental requirements of a successful design such as electrical power supply, air conditioning and data cabling. Best practice is achieved by bringing together the requirements of British Building Regulations, Statutory Instruments, EC Directives and British and European 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 lead the students through all the steps needed to arrive at a baseline design of a modern data centre.
