Optimizing Power and Data Center Resources Jim Sweeney Enterprise Solutions Consultant, GTSI Going Green Lots of Good Reasons: In the next decade, growth in server shipments will be 6x and 69x for storage. IBM / Consultant studies Per square foot, annual data center energy costs are 10 to 30 times more than those of a typical office building. William Tschudi, March 2006 Data centers have doubled their energy use in the past five years. Koomey, February 2007 US commercial electrical costs increased by 10 percent from 2005-2006. EPA Monthly Forecast, 2007 Energy costs for servers will match acquisition costs by 2012. IDC 2007 What Percentage of Energy Actually Does Productive Work? DATA CENTER Generation & Distribution Energy Source 100% Power Supplies, UPS Cooling 16% 30% Mission Critical Apps Servers Silicon .003% 1% Where Does Power Go? IT Equipment = 30% Power: PDU: 5% UPS: 18% Switchgear: 1% Lighting: 1% Cooling: Chiller: 33% Humidifier: 3% CRAC: 9% Green is More Than Power Usage Energy-Efficient Systems: Cooling, UPS, power supplies, servers, and non-IT equipment Asset Procurement: Equipment is selected considering full lifecycle environmental impact, from technology providers with appropriate environmental policies and controls Building Construction: The physical building, its fixtures and fittings are designed and selected to be energy efficient and to make use of relatively low impact materials and construction techniques (LEED certification) Energy-Efficient Operations: The systems are monitored and operated to maximize energy efficiency Energy Source: Appropriate use of renewable or locally generated energy; solar, wind, hydro, geothermal, fuel cell, etc. Support Services: Selected and managed to minimize the environmental footprint Waste Management: Waste products and emissions are reduced, recycled, or reused Where to Reduce Consumption Right-size Power / Cooling equipment 30% Using a modular, scalable power and cooling architecture Some DC’s are over provisioned by 205% 8 – 10 to 1 is typical consolidation ratio (Can be as high as 30 to 1) Virtualize Servers Not always possible 40% New power saving mode creates even more opportunity for savings Radical move for some organizations.

Summary • Virtualization has the potential to yield the greatest impact in the data center. • While some things can only be implemented with new buildings, everyone can do SOMETHING to move towards green. • Green is not a one time event. Good ideas are in the white paper. Continuous monitoring and improvement is the norm!
