  • Cloud Computing: The Green Grid

    1. 1. The Green Grid Energy Efficient, Environment Friendly Data Centers
    2. 2. IT data centers today <ul><li>Lots of servers </li></ul><ul><li>Lots of cables/switches </li></ul><ul><li>Lots of coolers/Aircos </li></ul><ul><li>Lots of UPS/Battery packs </li></ul><ul><li>Lots of floor space </li></ul><ul><li>Lots of energy usage </li></ul>
    3. 3. Critical questions asked when building data centers <ul><li>Where should we place it? India, China, Kampala, Amsterdam or San Francisco? </li></ul><ul><li>What will it cost? </li></ul><ul><li>How large will/can it be? </li></ul><ul><li>Critical reasoning driven by “traditional IT mentality” </li></ul>
    4. 4. Challenges faced by the IT Management <ul><li>Scalability: Be able to add new services as needed </li></ul><ul><li>Expandability: Floor space for more racks, cabling, cooling, switches, UPS/battery packs etc </li></ul><ul><li>Redundancy: Backup (hardware, software and extra staffing), cooling, </li></ul><ul><li>Try achieving this with lower operational costs!!! </li></ul>
    5. 5. Data Center Today <ul><li>Power wastage </li></ul>
    6. 6. So what are we doing wrong in our data centers? <ul><li>Nothing actually*, but we ARE spending more money on energy than on our IT services. </li></ul>
    7. 7. Data Center Efficiency Intro <ul><li>PUE = Power Usage Effectiveness = (total power) / (IT equipment power) </li></ul><ul><li>DCE = Data Center Efficiency = (IT equipment power) / (total power) </li></ul>
    8. 8. Our (environmental) goal <ul><li>To grow bigger without getting fatter! </li></ul><ul><li>Use less hardware: Use blade servers, use servers with multiple sockets, multi-core processors </li></ul><ul><li>Virtualization: Pack many virtual machines in a single server/desktop (both server and desktops), OS partioning, storage & network virtualization </li></ul>
    9. 9. Virtualization: what is it? <ul><li>This is what it is! </li></ul>
    10. 10. How can Virtualization help? <ul><li>It helps you to add many virtual servers in one “physical” server </li></ul><ul><li>You save investment costs (up to 70% in some cases: no need to buy servers as applications grow) </li></ul><ul><li>You save on operational costs: energy, power, cooling, electricity bills, server support contracts etc </li></ul><ul><li>You lay a foundation for an “fully automated, self managing” IT infrastructure </li></ul>
    11. 11. Data Center: Before (virtualization) <ul><li>One-to-one ratio of function to device </li></ul><ul><li>Support from multiple sources </li></ul><ul><li>Inefficient utilization of hardware </li></ul>
    12. 12. Data Center: After (virtual infrastructure) <ul><li>Pools of computing resources </li></ul><ul><li>Standardize on preferred hardware </li></ul><ul><li>Simplify operational support </li></ul><ul><li>Decrease footprint of each solution </li></ul><ul><li>Hardware support from preferred vendor </li></ul><ul><li>Efficient utilization of hardware </li></ul>
    13. 13. Before/After… (an example from a “lean” IT department) <ul><li>1,000 servers with DASD </li></ul><ul><li>200 racks </li></ul><ul><li>3000 network cables </li></ul><ul><li>400 power whips </li></ul>
    14. 14. After… <ul><li>50 servers with SAN and NAS </li></ul><ul><li>10 racks </li></ul><ul><li>300 network cables </li></ul><ul><li>20 power whips </li></ul>
    15. 15. Most data centers by 2010
    16. 16. Why should we go for “Green Grid” anyways? <ul><li>(Corporate & State) Environmental Responsibility : Ethical today, compliance tomorrow </li></ul><ul><li>US and Europe will soon enforce regulatory compliances, but it won’t stop there… </li></ul><ul><li>Green Grid organizations are eligible for Govt subsidies as they move on to demonstrate energy savings </li></ul>
    17. 17. Lets compact the earth’s life in a film lasting one year! <ul><li>Humans have seriously altered the biosphere in the last 2 seconds! </li></ul>
    18. 18. CO2 Emissions explode
    19. 19. We have protected our environment in the past…
    20. 20. And with virtualization we can do that again!
    21. 21. Questions? <ul><li>Presenter: Tarry Singh </li></ul><ul><li>References: “Paths to a Green world” - Jennifer Clapp and Peter Dauvergne </li></ul><ul><li> , , , </li></ul>
