Green IT

  1. 1. GREEN IT
  2. 2. GREEN IT Presented by. MADHUMITHA S SHILPA V
  3. 4. Early indicators of a rising ‘Green Business’ trend <ul><li>January 2007: </li></ul><ul><li>Marks and Spencer </li></ul><ul><li>CEO Stuart Rose committed </li></ul><ul><li>the company to become </li></ul><ul><li>carbon neutral and send </li></ul><ul><li>no waste to landfill by 2012 . </li></ul>
  4. 5. The Bad News:ICT Accounts for approximately .. 2% .. of global CO2 emissions
  5. 6. ICT’s global CO2 emissions
  6. 7. IT operations are challenged by operational issues
  7. 8. But this industry cloud has a Silver Lining <ul><li>There are substantial </li></ul><ul><li>inefficiencies in the </li></ul><ul><li>technology and use behaviors </li></ul><ul><li>that can be readily addressed… </li></ul><ul><li>..IT can significantly </li></ul><ul><li>contribute to control and </li></ul><ul><li>reduce the 98% of CO2 </li></ul><ul><li>emissions caused by other </li></ul><ul><li>activities and industries. </li></ul>
  8. 9. What percentage of energy actually does productive work?
  9. 10. Getting started with green IT <ul><li>Update your hardware </li></ul><ul><ul><li>Using energy-efficient hardware is a simple way to reduce your carbon footprint </li></ul></ul><ul><li>If it’s not in use, turn it off </li></ul><ul><ul><li>New technologies can help you switch off the lights—and other idle resources—automatically </li></ul></ul><ul><li>Virtualize, virtualize, virtualize </li></ul><ul><ul><li>Virtualization lets you get more done with less hardware, lowering your energy consumption </li></ul></ul><ul><li>Straighten out your storage </li></ul><ul><ul><li>Learn four techniques for using energy-hogging hard drives more efficiently </li></ul></ul><ul><li>Consolidate data centers </li></ul><ul><ul><li>Eliminating data centers or building new, “green” ones cuts power utilization dramatically </li></ul></ul>
  10. 11. Optimize IT Energy use <ul><li>Protecting and Backing up Data </li></ul><ul><li>High Availability and Virtualization </li></ul><ul><li>Managing Power Wisely </li></ul><ul><li>Designing Efficient Data Centers </li></ul>
  11. 12. IT transformation - Energy savings <ul><li>Provide energy efficient technology and products for the Commonwealth such as Energy Star qualified computers, printers and monitors. </li></ul><ul><li>Reduce the costs of power and cooling through the consolidation and virtualization of the IT server infrastructure. </li></ul><ul><li>Promote environmental improvement by increasing levels of efficiency that ultimately reduce greenhouse gas emissions. </li></ul><ul><li>Audit compliance with “green” or “emissions” objectives, regulation and standards. </li></ul><ul><li>Work toward establishing an enterprise-wide awareness to staff the expected power </li></ul><ul><li>management settings requirements and best practices for energy conservation – Ensure that everyone understands their personal responsibility to do so. </li></ul>
  12. 13. Virtualization <ul><li>The process of running </li></ul><ul><li>two or more logical </li></ul><ul><li>computer systems on </li></ul><ul><li>one set of hardware . </li></ul>
  13. 14. Server virtualization <ul><li>Virtualization one of the most effective tools for cost effective, greener computing. </li></ul><ul><li>Reduce the cost of power and cooling through the consolidation and virtualization of the IT server infrastructure. </li></ul><ul><li>$300 -$600 per year in energy savings for every server removed through virtualization based consolidation. </li></ul><ul><li>Virtualization helps a company/enterprise lower power and cooling consumption, by reducing the machines and servers it needs. </li></ul>
  14. 15. System activity display with power management
  15. 16. Top Data Centre challenges
  16. 17. Holistic Look at Data Center Impact Reduce IT Load <ul><li>Consolidate & virtualize servers </li></ul><ul><li>Storage Area Network </li></ul><ul><li>Remove decommissioned servers from rack and power </li></ul><ul><li>Right sized servers </li></ul><ul><li>Dynamic power load management </li></ul><ul><li>Dynamically migrate workloads from underused servers to enable them to be shut down </li></ul><ul><li>Use a low-power state or shut down servers when not in use </li></ul><ul><li>Purchase Green Servers (energy star, RoHS, EPEAT) </li></ul><ul><li>Architectural/software choices that promote efficiency </li></ul><ul><li>Raise temperature in data center </li></ul><ul><li>“ Get our ducts in a row ” (step 1) </li></ul><ul><li>Bottom-to-top airflow (step 2) </li></ul><ul><li>Replace HVAC w/higher efficiency </li></ul><ul><li>Options for free cooling or reuse of heated air </li></ul>Reduce Cooling Load <ul><li>DC air pressure at 5% above </li></ul><ul><li>DC thermal analysis & leak detection </li></ul><ul><li>Use blanking panels </li></ul>Reduce Power Distribution Losses <ul><li>Data Center </li></ul><ul><li>ECS monitoring/management </li></ul><ul><li>Use of renewable offsets </li></ul><ul><li>More efficient UPS+generators </li></ul><ul><ul><li>Need to improve efficiency </li></ul></ul><ul><ul><li>Rotary vs. cell </li></ul></ul><ul><ul><li>Better power monitoring </li></ul></ul><ul><li>Server </li></ul><ul><li>More-efficient power supplies </li></ul><ul><li>Focus on fans/blowers </li></ul><ul><li>Electrical conversion at the server </li></ul><ul><li>Energy management software </li></ul>
  17. 18. Benefits of data centre
  18. 20. Pc/laptop power management <ul><li>PCs, monitors account </li></ul><ul><li>for more than a third </li></ul><ul><li>of ICT power consumption </li></ul><ul><li>and CO2 emissions. </li></ul><ul><li>Sixty percent of PCs are </li></ul><ul><li>left on after hours. </li></ul><ul><li>So the fix is educate staff, </li></ul><ul><li>use a lower power state </li></ul><ul><li>such as stand by, for </li></ul><ul><li>PCs and monitors after hours. </li></ul>
  19. 21. Greening printers and printing <ul><li>Average office worker </li></ul><ul><li>prints 1,000 pages/month, </li></ul><ul><li>40 lbs/month. </li></ul><ul><li>The paper itself consumes </li></ul><ul><li>10x the energy of printing </li></ul><ul><li>on it. </li></ul><ul><li>So the fix is print less </li></ul><ul><li>measure and analyze </li></ul><ul><li>document flows. </li></ul><ul><li>Consolidate the printers into </li></ul><ul><li>fewer, standard, low impact </li></ul><ul><li>that share the same consumables. </li></ul>
  20. 22. Greening the staff.. <ul><li>Save energy by encouraging staff to power down their equipment when not in use. </li></ul><ul><li>Embrace virtualization technologies (using IT environments more </li></ul><ul><li>efficiently) and explore the consolidation of data processing and </li></ul><ul><li>storage. </li></ul><ul><li>Dispose of your technologies in a sound and environmentally </li></ul><ul><li>friendly manner, and </li></ul><ul><li>Utilize technologies that allow staff to stay connected in remote </li></ul><ul><li>locations, participate in meetings without travel, and respond quickly during emergency situations. </li></ul>
  21. 23. <ul><li>Reduce </li></ul><ul><li>Consume fewer servers, printers, so forth by increasing utilization- virtualize. </li></ul><ul><li>Stop over provisioning; improve capacity planning. </li></ul><ul><li>Turn equipment off, turn power management on. </li></ul><ul><li>Reuse </li></ul><ul><li>Extend the life of assets by reusing them within the enterprise and externally. </li></ul><ul><li>Recycle </li></ul><ul><li>Ensure and validate the correct disposition of all electronic equipment. </li></ul><ul><li>Buy recyclable products. </li></ul>
  22. 24. What does the future hold..? <ul><li>Increased legislation, regulation and tax breaks — power consumption, hazardous substances and e-waste. </li></ul><ul><li>Energy management across the ICT infrastructure, creating a more dynamic sense-and-respond environment. </li></ul><ul><li>More-efficient and smarter cooling, UPS and power supplies in the data center and for client devices and so on. </li></ul><ul><li>Better power management at every level — processors, PCBs, systems, operating systems and applications. </li></ul><ul><li>Power consumption as a design criterion for software and energy profiling. </li></ul>
  23. 25. Conclusion <ul><li>Green IT Approaches Span the Globe brings in to focus the steps to reduce the carbon footprint of information technology at every point in the lifecycle of their government systems, from purchase and production through usage and ultimate disposal. </li></ul><ul><li>The next wave of green IT: Broader change in processes, behavior, and company culture </li></ul>
  24. 26. <ul><li>The largest enterprise of all .. the </li></ul><ul><li>environment </li></ul>
