Improving Cooling efficiency in tomorrow's data centre Kevin Hughes, APC Senior Systems Engineer
© 2003 APC corporation. Agenda The Problem: High Density IT Equipment Legacy Cooling System Limitations The Solution: APC InfraStruXure In-Row Cooling Innovation The Benefits of IR Cooling Methodology Summary
© 2003 APC corporation. The Problem Average rack in a typical data center is under 2 kW Full deployment of high density servers (10-20 kW per rack) would greatly exceed the power and cooling ability of the typical data center Providing 10-20kW of cooling per rack is technically impractical to infeasible using conventional methods
© 2003 APC corporation. What is the industry saying ? “You cannot keep it a secret, performance-per-watt will become critical over next decade. […] for every watt that goes into a processor you will use another watt to cool it“, Steve Prentice, research VP at Gartner June 2006 "There's no question that the issue of power and cooling is a growing concern. The assumptions used for building data centres have been blown away", John Humphreys, IDC Analyst
© 2003 APC corporation. Industry statistics Power & cooling #1 issue for CIOs 70% of respondents recently said power and/or cooling issues are now their single largest problem facing their datacenters Projections are 48% of IT budget spent on energy, up from 8% Source: Gartner CIO Survey

The Solution: In-row rack-coupled CRAC

© 2003 APC corporation. Summary Your data centre’s Network Critical Physical Infrastructure (NCPI) must support dynamic business needs High-density server deployment requires unique cooling and power solutions In-row, close-coupled cooling maximises efficiency NCPI Health Check increases availability and reduces TCO of existing systems APC’s original In-Row Cooling is the most cost effective, agile solution to today’s cooling challenges Complexity is not a necessity. Do not tolerate unpredictable performance & inflexibility Doing high density the right way costs less
