The greenest electrons are the ones that you don’t use.

The Case for Saving Power

Electricity Costs Are an Increasing Drain on IT BudgetsBusinesses are using more servers than ever beforeMore powerful servers use more electricityElectricity costs have risen significantly since 2000

Environmental ConcernsExcess power use contributes to global warningSaving power can facilitate carbon trading

Three Strategies for Energy Efficiency

IT Energy Efficiency ApproachesEnd User Devices

EPEAT, Energy Star, Windows Vista, Laptops, Thin ClientsPower Management, wake-on-LAN, scheduled tasksE-cycling

ServersSPEC Power, Climate Savers Computing, Windows Server 2008 Power Management, virtualizationSoon: Energy Star

NetworkingProvision correctly, turn off unused equipmentCommunicate importance of power efficiency to vendors

Storage (5% of the Total Data Center Electricity Use in 2006)Consolidation, thin provisioning, data de-duplication, diskless servers

Data Centers (PUE)Airflow and cooling, utilization, measurementSoon: Energy Star

Reduce IT Energy Consumption“Use what you need when you need It"

Built-in Energy Efficiency Power management on by defaultThirty six new power management featuresWindows Server 2008 – 10% more energy efficient

Resource OptimizationEnd-to-end virtualization solutionManaging and enforcing group policies

Guidance and EducationAssessment and planning toolkitData center best practicesMSN 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

Manage Energy Effectiveness"You can't monitor what you can't measure"

Centralize Control to One PlaceComprehensive end-to-end system monitoring health at all levelsProactive reporting of energy usageStreamlined group policy management

Analyze Operations Collect data from various sources in one placeUse BI to manage data and calculations Create scorecards to monitor and plan initiatives

Monitor GoalsConsider footprint across the organizationBuild metrics into standard reportingReport 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

ManageRemove Your Energy Waste:10%-30% of servers do nothing (Uptime Institute, USA)

Use Microsoft System Center to reduce number of running serversOperations Manager 2007 informs you about performance monitoring over timeConfiguration 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

Rethink Business Practices"Increase productivity and reduce footprint"

Reduce Business TravelCut travel costs by 10-30% with Microsoft UC (Forrester, Oct ’07)Reduce travel time and lost productivityUC can make a difference: the EU-25 could save ~22 MT CO2 per year with 20% travel reduction (WWF)

Reduce Commuting with TeleworkImprove employee satisfaction and retentionGrowing 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 SpaceNew World of Work. Workplace Innovation and productivityMore flexible work spaceLess 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

Basic Guidelines for Saving Power

Know Your WorkloadDeploy Efficient Hardware

80% or 90%-efficient Power Supplies2.5” drives (use less power than 3.5” drives)Modern processors (smaller nm die = less power)Lower power memory, sized for your workloadPlatforms are wasteful! Fans, VRMs, chipsets, etc.

Raise Utilization (and Efficiency) by Consolidating Servers Where You Can (Hyper-V, Multi Role)

Boot from SAN Can Save Power

Intelligent Timer Tick Distribution (Tick skipping)

Extends processor sleep states by not waking the CPU unnecessarilyOne processor handles the periodic system timer tick; other processors are signaled as necessaryNon-timer interrupts will still wake sleeping processorsTimer coalescing

Helps combine software timers such that for each time the processor comes out of a low-power state, multiple timers can be expired

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
