Emerging Technologies: Green IT

  1. 1. Emerging Technologies:Green IT Copyright © 2011 by J. Y. Tsai
  2. 2. Agenda• What is green IT?• Key reasons to adopt green IT• Emerging green technologies and benefits – Cloud computing – Virtualization – Green data centers• Products of top green technology firms• Success metrics used by senior managers
  3. 3. Green ITGreen IT or green computing is thestudy and practice of using computingresources in ways that help reduceenergy and operating costs, enablesustainable business practices andreduce the environmental impact of ITpractices in the larger community
  4. 4. Reasons to Adopt Green IT• Broader interest and emphasis on corporate social responsibility (CSR)• Rising energy costs• Attract and retain customers – Increasing public awareness – Positive environmental brand image• Government agencies have implemented standards and regulations that promote green computing
  5. 5. Cloud Computing• Cloud computing refers to computing services provided over the Internet (or “cloud”), whereby shared resources, software, and information are provided to computers and other devices on demand• Pros: fast start-up & business agility, low entry cost with on demand pricing• Cons: highly dependent on provider, privacy and security risks
  6. 6. Cloud Computing
  7. 7. Green Benefits of the “Cloud”• Green Benefits – Increased efficiencies (power efficiency) – Resource sharing minimizes wasted resource – Operating servers at higher utilization rates• Examples: – Amazon’s Elastic Compute Cloud (EC2): Rent virtual-machine instances & hardware – Google’s App Engine: Web development platform to build and host Web applications
  8. 8. Virtualization• Virtualization means to create a virtual version of a device or resource, such as a server, storage device or network where the framework divides the resource into one or more execution environments• Pros: server consolidation, resource flexibility, portability & disaster recovery• Cons: unpredictable performance, risky to put multiple systems on one host
  9. 9. Virtual Desktop
  10. 10. Green Benefits of Virtualization• Green Benefits – Cut power demand (electricity for powering and cooling) through consolidation – Get more out of existing resources and reduce costs by shrinking number of servers• Examples: – VMware Server Virtualization: Partitions a physical server into multiple virtual machines – Microsoft Virtual PC: Run multiple operating systems on a single physical computer
  11. 11. Green Servers and Benefits• Solution to the data center energy crisis• Higher performance servers that require less energy consumption• Some contain internal cooling technology or smart sensors that monitor heat created by the server and adjust fans• Unified server cabinet for clustering apps• Modular tower can add processing power and memory capacity as needed
  12. 12. Data Center Transformation
  13. 13. 10 Steps to Green Data Center1. Evaluate energy efficiency (monitor & reduce)2. Redesign cooling system (concentrate cooling)3. Reconsider redundancy (operate on current needs)4. Use adjustable equipment (scalable and modular)5. Virtualize your storage (remap apps for efficiency)6. Use ENERY STAR-rated appliances7. Donate or recycle legacy servers (reuse parts)8. Look outside the data center (natural lighting)9. Research alternative power sources (solar, wind)10. Get your management involvedSource: Hengst (2008)
  14. 14. Newsweek’s Top Green RankingSource: http://www.newsweek.com/feature/2010/green-rankings.html
  15. 15. #1 Dell • Dell Green Store products: environmental certifications (ENERGY STAR, EPEAT, etc.) • Laptops & desktops use less energy and environmentally sensitive materials; recyclable • Servers are compliant with Europe’s toxic laws and takes less power to cool • Monitors include on, sleep and off modes so customers can manage power consumption
  16. 16. #2 Hewlett-Packard • HP Eco Highlights Products: environmental certifications (ENERGY STAR, EPEAT) • Desktop, notebook, & monitors • Data center transformation solutions – Devise & implement sustainable energy-efficient strategy – Improve power usage effectiveness (PUE) – Changes in layout, equipment or cooling capacity – Move to industry best practices
  17. 17. #3 IBM • IBM Content Collection and Archiving software eliminates unnecessary paper trails and reduces content storage • Tivoli Monitoring for Energy Management software monitors and helps manage energy usage of IT and facility resources (PCs, monitors, etc.) • IBM virtualization solutions for server, storage, desktop, etc.
  18. 18. Green Success Metrics
  19. 19. Design • Strategic Planning • Business Process Reengineering • IT Infrastructure and System Engineering • Space Planning for IT • Waste Management Process DesignManagement Education• System Procurement & RFP’s • Staff Training• Expense Analysis & Cost • Employee Awareness Programs Reduction • Public Awareness and Outreach• Project Management • Supplier Education Programs• Green Procurement Design• Operations Management
