IT and Data Center – The Problem and the Solution
“Today, it takes less than half the energy to produce a dollar of
economic output as it did in 1970…Information & communication
technologies have played a critical role in reducing energy
waste…from sensors & microprocessors, to smart grids &
virtualization…”
Information and Communication Technologies: The Power of Productivity, ACEEE Report #E081, Feb. 2008

State of the US Industry – EPA Report to Congress
Trends in Data Center Energy Use:
• Data center sector consumed about 61 billion KWh in 2006
– Equates to ~1.5% total U.S. electricity consumption and ~$4.5 billion
• Projected to increase to 100 billion kWh in 2011
– Equates to ~2.5% of total U.S. electricity consumption and ~$7.4 billion

Cooling Airflow Management
Three categories of air movement challenges
• Below floor obstruction
• Raised floor performance
• Above floor circulation
42U Confidential ©2008 42U All rights reserved
Assessing Your Current Environment Should Result In…
• Holistic understanding of your
data center’s environment• Increased Awareness of your
critical risk factors• A benchmark of performance
metrics• A punch list of opportunities for
improvement
42U Confidential ©2008 42U All rights reserved
Getting Started…
• Calculate PUE and DCiE• Perform a complete inventory of your equipment• Include the cost of power when evaluating new
equipment• Address the easy fixes• Track and share metrics

Cooling: Total Cost of Ownership
• Real Estate savings– Having the ability to cool dense loads allows for
server consolidation into a single rack, or adoption of denser server technologies such as blades
• Running cost savings– Close coupled cooling allows for multiple savings in
regards to energy • Lower fan energy costs• Lower lighting cost for smaller, more dense data center• Lower chilled water plant costs• Evaporative and dry free coolers
