Green IT & Virtualization Management

Joe ChouConsultantMicrosoft Technology Center

Agenda

• Green IT goals• Cooling and Power Consumption• Power Saving on servers• Power Saving on Workstations• Cost Saving

Corporate benefits of “Green IT”• Businesses worldwide can save

$800 billion in annual energy costs by 2020

• Companies can also reduce global greenhouse gas emissions by 15%

• American companies are interested in cost-cutting initiatives, and Europeans are more focused on improving brand image with corporate responsibility—but both factors benefit all types of businesses

Green IT goals• Gartner defines green IT as "optimizing

processes to reduce total resource consumption and waste output.“

• Why Green IT for Enterprises– Save Money– Limited Electric Utilities– Reduce the use of energy, water, and space– Required by law (carbon footprint)– Suggested by IT venders

Actually It's The Energy Cost Which Matters (Not Only In IT)• Do you know what your IT energy costs are?

– Gartner: about 4% – 7% of your IT budget!

• Do you think energy costs will rise or decline?– Germany: +36,6% prize increase in last 6 years– Costs may double over the next 5 years?

“For every $ spent on server hardware, add the same amount

for power and cooling during lifetime!”

• Is “energy” a purchase criteria for your IT?• It might be for your car… but IT?

Average hardware prize vs. energy costs over 3 yearsGartner: Why “Going Green” will become essential for data centers 10/2006

Gartner: Conceptualizing 'Green' IT and Data Center Power and Cooling Issues, 9/2007

Now the situation is• Data center managers

now must prioritize investment in efficient power and cooling systems to lower the total cost of operating (TCO) of their facilities.

Datacenters Are One Of The Biggest Areas To Save Energy And Money• In US: 60 billion KWh (1,5% of total US electricity)

or more than all US color TVs!

• Consumption growing at 12% annually– 40% of energy needs from banks

already IT relatedUS Env. Protection Agency (EPA) report 8/2007Green IT, Swiss Innovation Outlook, IBM Switzerland

There Are Best Practices To Help You With Your Datacenter Optimization• Optimized Datacenter Design includes

– Floor layout, hot-/cold-aisle configurations– Clean up cables, empty spaces (“air holes”) – Scalable and energy efficient power-, lighting- cooling

equipment (humidifier really needed?)– (Dynamic) heat-map

• Adjusted at changes

Power Saving on servers

Power Saving on servers

• Go virtualization– Replaced several small server boxes with one more

powerful server box– Transfer everything in several small server boxes into

some image OS in a more powerful server box– Go clustering for the powerful server box if HA is a

concern• MSDN and TechNet servers are all virtualized

Virtualization Green• Environmental Impact

• Energy costs to go over 50 % of the total IT budget for a typical data center

• daily power consumption of a typical datacenter = monthly power consumption of thousands of homes

• 61 billion kilowatt hours going toward data centre energy consumption

• 10-15 more power plants needed by 2011 to keep up with data centre power consumption

• x86 hardware consumes ~80% of the normal workload power even when idle

• Virtualization Promise

Virtualization can reduce energy usage by 90% Virtualizing 100 servers eliminates estimated 500K lb CO2 (annual emissions) 95% or over 30M servers are still to be virtualized

First Step: Avoid Unnecessarities• 10%-30% of servers do a little bit more than

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 and the software usage (eventually via CAL tracking)

• Same might be true for other (IT) equipment (Routers, Switches)

Second Step: Consolidate• Consolidate your servers where possible

– Consolidate file and print servers– Use Application virtualization for terminal server – Migrate to Exchange 2007 and

Microsoft Office SharePoint Server 2007– Microsoft Assessment & Planning 3.0 is the key– Consolidate SQL servers

Third Step: Use Right Hardware

hardware you need to run • Exchange 2007• Microsoft Office SharePoint Server (MOSS)• SC Operations Manager 2007 SP1

Windows Server 2003 Windows Server 2008

Windows Server 2003 Versus 2008

How System Center Configuration Manager Can Help You (1)• Identify the correct OS version

– Deploy Windows Server 2003 SP2 – Upgrade to Windows Server 2008

• Check for AMD drivers on Windows Server 2003 machines and right bios version– Deploy driver if needed– Use Dell, HP, IBM extensions for bios update

• Run the test script to see what’s possible– Collect information via HW inventory

Savings Summary For Servers• Efficient (dynamic) hardware is the key• Activate free Windows software features• Now do the math…

– 2 Mio Server shipped in Q2-07 ~ 8 Mio/year– Assume 50% runs on Windows – If each of them would save 10% (~400 Wh)

~1,4 TWh savings per year! (Simply by releasing a new server OS)

This does NOT include additional savings for cooling etc!

But Don't Stop At Your Servers!

Windows Vista And Server 2008 Allow More Granular Fine Tuning

Power saving on Workstations• Windows Vista is Microsoft’s most well managed

operating system to provide energy-efficiency• TCO savings is a compelling reason for deploying

Windows Vista.• Define the computer usage scenarios then setup

power saving models.

Microsoft Assessment Configuration Pack for ENERGY STAR Power Management for SC ConfigMgr 2007This Configuration Pack uses these ENERGY STAR defined efficiency levels and recommendations as follows:

Have computers enter system standby or hibernate after 30 to 60 minutes of inactivity. Have monitors enter sleep mode after 5 to 20 minutes of inactivity. Create a warning notification if screen savers are not disabled. If one is enabled, the wait timeout period should be less than the monitor sleep setting.

This Configuration Pack applies only to desktop and notebook computers that are running Windows XP or Windows Vista operating systems.

Summary (5 Steps To The $100 Tables)

• Shutdown systems you don’t need (server) or when you don’t need them (PCs)

• Use the right hardware for your needs:– Laptops vs. Office PCs vs. “gaming” PCs

• Consolidate server on 64bit platform• Virtualize if consolidation won’t work• Use Windows power features

It's Easier With System CenterServer Management Suite Enterprise includes• SC Operations Manager

(to find “unused” server)• SC Virtual Machine Manager

(for consolidating & virtualizing)• SC Configuration Manager

(for enabling power profiles )(for DCM reporting & asset information)

• SC Capacity Planner (for hardware right-sizing)
