Transcript

  • 1. Green(er) Green(er) Computing • Steve Young, CTO, Judson ISD • Green Computing Think Tank San Antonio, Texas, 9/17/2009
  • 2. About Judson ISD • 4th largest public school district in Bexar County, Texas (San Antonio area) • About 21 000 students and 3 000 employees 21,000 3,000 • 30 IT staff members • Over 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
  • 3. Green Computing – the Misnomer • Can computing really be “green”? • Technology is not particularly green by b most measures t • While technology can offer enormous productivity and efficiency gains…. • It can have a huge negative impact on the environment: • Materials use • Energy consumption • H t creation (and need for Heat ti ( d df cooling) • Discarding of old devices g
  • 4. Making Technology Greener • B t t h l But, technology can be made much greener by b d h b managing its negative impacts on the environment • Look at how it makes sense for your organization to limit or improve: • Materials consumption • Energy use • Heat creation (and need for cooling) • Di Discarding of old d i di f ld devices
  • 5. Reasons for IT to be Greener • Economics – Save $$$ • Reduce electricity consumption • IT now responsible for paying its ibl f i it utility bills • Social responsibility • Concern for environment • Can be good for public relations • Cooling already at capacity
  • 6. Major Green Economic Driver • Energy Costs • Energy costs often not seen by IT • But are a major organizational expense • In San Antonio, CPS Energy estimates 50% increase in bills in just 10 years • Bills projected to rise at an even faster rate after 2020 • Many utilities now offer rebates for conserving energy mysanantonio.com 09/06/2009
  • 7. Green Computing Initiative (GCI) at Judson ISD
  • 8. 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 equipment 3. Consolidating and virtualizing storage on SAN 4. Upgrading to more energy efficient servers pg g gy 5. Purchasing Energy Star rated and EPEAT certified computers 6. Utilizing energy efficient LCD monitors and phasing out CRT monitors 7. Eliminating almost all ink jet printers and providing a much smaller quantity of shared laser printers and networked copiers
  • 9. Judson ISD Green(er) Computing Steps: 8. Automating shutdown of most district computers 9. Recycling toner cartridges 10. Establishing procedures for redistribution, reuse, and recycling of gp , , y g technology assets 11. Recycling of disposed technology assets with company which certifies that is uses responsible environmental practices and tries p p to reuse as many parts as possible 12. Pushing large volumes of student data to Judson ISD parents via web applications, decreasing paper usage pp , gp p g 13. Intensive desktop virtualization using nComputing X-Series devices, saving the district money on acquisition, energy, cooling, and network wiring g
  • 10. Desktop Virtualization at Judson ISD • Chose non-traditional approach Ch t diti l h • 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 option • most staff supportable option ff bl i • most green option • What we chose • nComputing X300 C ti • 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.
  • 11. How desktop virtualization benefitted JISD • Lower Acquisition Costs for 3,044 Seats Acquisition for a PC only deployment q y p y $ 2,374,320 Possible additional network growth $ 776,220 Acquisition cost for X Series Deployment Shared PC's $ 593,580 Access Terminals (X Series) $ 152,200 Extra Monitors $ 285,375 285 375 Keyboards & Mice $ 45,660 MS OS Licensing $ 108,594 Total X Series Acquisition Cost $ 1,185,409 Savings of 50% Numbers calculated in house by Judson ISD
  • 12. How desktop virtualization was greener • Th There was much less physical hardware deployed hl h i lh d d l d • 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 computers g p • EPEAT gold/Energy Star computers with LCDs • Much more energy efficient than older computers • X S i virtual machines use 1 watt electricity per seat Series i t l hi tt l t i it t • At least 70% less HVAC capacity was needed • 75% less building electrical capacity was needed per computing seat • Network port needs trimmed by 75%
  • 13. Energy costs with desktop virtualization Judson ISD's School Year Energy Cost Comparison $29.78 $27.60 $30.00 $30 00 $25.00 $20.00 $15.00 $11.78 $7.44 $10.00 $5.00 $ $- Annual Energy Cost of Annual Energy Cost of Annual Energy Cost of JISD's Annual Energy P3 and CRT Monitor d M it a" "green" D l C " Dual Core PC Dual Core w/ 3 D lC / Cost Per Seat using C tP S t i w/LCD terminals nComputing X-Series Numbers calculated in house by Judson ISD

  • 18. 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 $200,000 $150,000 $100,000 $100 000 $50,000 $155,111 $54,000 $43,649 $43 649 $- $33,907 $23,556 Year 1 Year 2 g Savings Year 3 Savings Year 4 Savings Total Savings Savings Numbers calculated in house by Judson ISD
  • 19. In Conclusion • Go green(er) with a purpose in mind • Calculate savings and TCO for large projects • A project that makes sense for one organization, may j t th t k f i ti not be right for another • Sell your initiatives & successes – IT often does not excel at public relations • Questions • Steve Young • CTO, Judson ISD • syoung@judsonisd.org • (210) 945-5562
