4. Energy: A Key Component in Green IT • Green Strategies Vary • Organizational priorities • Competitive landscape • Market and geography factors • Energy is a Common Requirement • Underrated and overlooked • Growing broader awareness • Climate change impacts • Worldwide Energy Supply Issues • Demand is on the rise • Current supply is limited • New sources in flux How do you do more with less?

5. Bring Energy Efficiency to IT • Desktop-> Server-> Data Center • Power Management at every stage • Deliver guidance and management • Employee-> Team ->Organization • Bring visibility to environmental footprint • Mobilize the workforce • Consider Energy in Every Decision • Maximize existing HW/SW • Do more with less • Five opportunities • Virtualize • Decomission unused equipment • Stop over-provisioning • Use Power Management features • Change the power state when equipment is not in use The greenest electrons are the ones that you don’t use.

6. The Case for Saving Power • Electricity Costs Are an Increasing Drain on IT Budgets • Businesses are using more servers than ever before • More powerful servers use more electricity • Electricity costs have risen significantly since 2000 • Environmental Concerns • Excess power use contributes to global warning • Saving power can facilitate carbon trading

7. Power Usage in the Present • Electricity usage by servers and equipment doubled between 2000 and 2005 • Server power and cooling uses 123 billion kWh/year worldwide • 0.8% of all worldwide power usage (1.5% US) • 18.2 million metric tons of coal; 69.7 million barrels of oil • Equivalent to the yearly electricity consumption of the entire nation of Poland • Could double again by 2011 USA World Source: Estimating Total Power Consumption by Servers in the U.S. and the World, Jonathan G.

13. Reduce IT Energy Consumption“Use what you need when you need It" • Built-in Energy Efficiency • Power management on by default • Thirty six new power management features • Windows Server 2008 – 10% more energy efficient • Resource Optimization • End-to-end virtualization solution • Managing and enforcing group policies • Guidance and Education • Assessment and planning toolkit • Data center best practices • MSN Green Using virtualization, The Scooter Store is saving 150 -200K per year in HW costs, and increasing its ROI by 50%. “We have 13 servers doing what 52 servers used to do”, – Barrett Blake, IT Architect

14. Manage Energy Effectiveness"You can't monitor what you can't measure" • Centralize Control to One Place • Comprehensive end-to-end system monitoring health at all levels • Proactive reporting of energy usage • Streamlined group policy management • Analyze Operations • Collect data from various sources in one place • Use BI to manage data and calculations • Create scorecards to monitor and plan initiatives • Monitor Goals • Consider footprint across the organization • Build metrics into standard reporting • Report and manage environmental footprint from greenhouse gas emissions With Microsoft System Center Virtual Manager, Continental saved more than $2M in server costs, and speeded provisioning from 4 weeks to 2 hours

15. Manage • Remove Your Energy Waste:10%-30% of servers do nothing (Uptime Institute, USA) • Use Microsoft System Center to reduce number of running servers • Operations Manager 2007 informs you about performance monitoring over time • Configuration Manager 2007 informs you about Installed hardware and software (incl. CAL tracking) • Desired Configuration Monitoring helps you to keep your components and settings “green” • Same might be true for other equipment

16. Rethink Business Practices"Increase productivity and reduce footprint" • Reduce Business Travel • Cut travel costs by 10-30% with Microsoft UC (Forrester, Oct ’07) • Reduce travel time and lost productivity • UC can make a difference: the EU-25 could save ~22 MT CO2 per year with 20% travel reduction (WWF) • Reduce Commuting with Telework • Improve employee satisfaction and retention • Growing telework population: 46M in 2006, 58M by 2011 • US could save 5.1 B liters of fuel and 11.8 MT CO2 if everyone telworked 1.6days/week. (U of Maryland, EPA) • Reduce Office Buildings and Space • New World of Work. Workplace Innovation and productivity • More flexible work space • Less office buildings -> less energy Volvo IT estimates that just the Microsoft collaboration products alone save enough travel to eliminate 900 tons of carbon-dioxide emissions per month, and use of those tools is gradually increasing

20. Enhanced Power Management

21. Out-of-the-Box Power Savings

22. Centralized Power Management

23. Saving Power Through Virtualization • Each physical server creates a guaranteed minimum power usage overhead • Even at idle, a server can consume 60 percent or more of its maximum power draw • Dedicated servers typically run at far below capacity • Inefficient resource allocation leads to wasted power

24. More Servers, Same Power

29. Power Consumption – Power Supplies

30. Basic Guidelines for Saving Power • Know Your Workload • Deploy Efficient Hardware • 80% or 90%-efficient Power Supplies • 2.5” drives (use less power than 3.5” drives) • Modern processors (smaller nm die = less power) • Lower power memory, sized for your workload • Platforms are wasteful! Fans, VRMs, chipsets, etc. • Raise Utilization (and Efficiency) by Consolidating Servers Where You Can (Hyper-V, Multi Role)

32. Windows Server 2008 R2 Enhancements - Reduce • Reduce Power Consumption of Individual Servers • Rewritten processor power management engine • Improved Power Profile defaults • Storage Power Management enhancements • Core parking, tick skipping, timer coalescing • Hyper-V Makes Use of Most of Our Power Improvements, Including PPM (p-states, c-states)

34. R2 Power Efficiency Improvement

35. Storage Power Management Enhancements • Support for remove on delete • Asynchronous notification of media change foroptical devices • ATA Slumber • Optimize Link Power Management for SATA disks

36. Boot from SAN Can Save Power

37. Intelligent Timer Tick Distribution (Tick skipping) • Extends processor sleep states by not waking the CPU unnecessarily • One processor handles the periodic system timer tick; other processors are signaled as necessary • Non-timer interrupts will still wake sleeping processors • Timer coalescing • Helps combine software timers such that for each time the processor comes out of a low-power state, multiple timers can be expired

38. Core Parking • The Windows Server 2008 R2 default “balanced” power policy uses core parking in conjunction with p-state management to further improve the power efficiency of Windows, out of the box • This should be particularly effective on underutilized servers
