About Judson ISD• 4th largest public school district in Bexar County, Texas

(San Antonio area)• About 21 000 students and 3 000 employees• About 21,000 students and 3,000 employees• 30 IT staff members• Over 6,800 desktops and laptopsOver 6,800 desktops and laptops• Additional 2,550 virtual desktops (includes library desktops, which are not included on slide 11)

• 59 physical servers, 39 virtual servers • More info at http://www.judsonisd.org

Green Computing – the Misnomer

• Can computing really be “green”?• Technology is not particularly green b tby most measures• While technology can offer enormous productivity and efficiency gains….productivity and efficiency gains…. • It can have a huge negative impact on the environment:

• Materials use• Energy consumption

H t ti ( d d f• Heat creation (and need for cooling)• Discarding of old devicesg

Making Technology GreenerB t t h l b d h b• But, technology can be made much greener by managing its negative impacts on the environment

• Look at how it makes sense for your organization toLook at how it makes sense for your organization to limit or improve:

• Materials consumption• Energy use• Heat creation (and need for cooling)

Di di f ld d i• Discarding of old devices

Reasons for IT to be Greener• Economics – Save $$$• Reduce electricity consumption

IT ibl f i it• IT now responsible for paying its utility bills

• Social responsibilitySocial responsibility• Concern for environment• Can be good for public relations• Cooling already at capacity

Major Green Economic Driver• Energy Costs• Energy costs often not seen

by ITby IT• But are a major

organizational expense• In San Antonio, CPS Energy

estimates 50% increase in bills in just 10 yearsbills in just 10 years

• Bills projected to rise at an even faster rate after 2020

• Many utilities now offer rebates for conserving energyenergy mysanantonio.com 09/06/2009

Green Computing Initiative (GCI) at Judson ISD

Judson ISD Green(er) Computing Steps:1. Running virtual servers with VMWare, which reduces: number of

physical servers, power consumption, cooling, and data center space requirements.

2. Remote management of desktops, servers and network equipment3. Consolidating and virtualizing storage on SAN4. Upgrading to more energy efficient serverspg g gy5. Purchasing Energy Star rated and EPEAT certified computers6. Utilizing energy efficient LCD monitors and phasing out CRT

monitorsmonitors7. Eliminating almost all ink jet printers and providing a much smaller

quantity of shared laser printers and networked copiers

Judson ISD Green(er) Computing Steps:8. Automating shutdown of most district computers9. Recycling toner cartridges10. Establishing procedures for redistribution, reuse, and recycling of g p , , y g

technology assets11. Recycling of disposed technology assets with company which

certifies that is uses responsible environmental practices and tries p pto reuse as many parts as possible

12. Pushing large volumes of student data to Judson ISD parents via web applications, decreasing paper usagepp , g p p g

13. Intensive desktop virtualization using nComputing X-Series devices, saving the district money on acquisition, energy, cooling, and network wiringg

Desktop Virtualization at Judson ISDCh t diti l h• Chose non-traditional approach• Virtualized a host PC locally and increased PC access by 300%

• Why go the route we did?• Needed to offer increased computer access, but cost was the key factor• We chose the…

• lowest deployment cost optionff bl i• most staff supportable option

• most green option

• What we choseC ti X300• nComputing X300

• What it is?• Modified thin client• It virtualizes the host OS and shares the host’s resources

• What we deployed –• Deployed 761 X Series sets for an additional 2283 computing seats.

How desktop virtualization was greenerHow desktop virtualization was greenerTh h l h i l h d d l d• There was much less physical hardware deployed • Resulting in:

• less natural resources, packaging, etc are used at the onset• less materials that need recycling and end up in land fills at the end

of the life cycle

• Purchased greener host computersg p• EPEAT gold/Energy Star computers with LCDs• Much more energy efficient than older computers

X S i i t l hi 1 tt l t i it t• X Series virtual machines use 1 watt electricity per seat• At least 70% less HVAC capacity was needed• 75% less building electrical capacity was needed per• 75% less building electrical capacity was needed per

computing seat• Network port needs trimmed by 75%

How automated PC shutdown helps• Judson ISD started automated shutdown of school computers

in 2007• Numbers based on 25% of 4000 machines left on• Over time savings are less as PC base becomes more green

In Conclusion• Go green(er) with a purpose in mind• Calculate savings and TCO for large projects

A j t th t k f i ti• A project that makes sense for one organization, may not be right for another
