2009 Itc Green It

  1. 1. NEA-SEA ITC 2009 Cost of Electricity March 2009 ITC Jay Hall
  2. 2. Data Center Power Usage <ul><li>In 2005, Data Center power, including cooling, accounted for 1.2% of the total power used in the United States. </li></ul><ul><ul><li>This is equivalent to having 5 1000 MegaWatt power plants to just power data centers. </li></ul></ul><ul><ul><li>The United States houses between 30% and 40% of the world's servers. </li></ul></ul><ul><li>Power use by Data Centers was expected to increase up to 76% during 2008. </li></ul>
  3. 3. Power Costs <ul><li>Electricity use in servers doubled from 2000 to 2005. </li></ul><ul><ul><li>Annual growth rate of approximately 14%. </li></ul></ul><ul><li>Cooling a data center almost doubles the electricity cost. </li></ul><ul><li>Total cost (2006 dollars) for data centers nationwide was approximately $2.7 billion dollars. </li></ul><ul><ul><li>Approximately 23 billion kWh per year. </li></ul></ul>
  4. 4. Reducing Power Costs <ul><li>More efficient cooling </li></ul><ul><ul><li>Air Conditioning Replacement </li></ul></ul><ul><ul><li>Missouri NEA upgraded A/C units installed in the early 1980s this year. </li></ul></ul><ul><ul><li>Efficiency went from 6.0 to 10.3. </li></ul></ul><ul><ul><li>Assuming the electricity rate is 9 cents per kWh, the annual savings is $5,521. </li></ul></ul><ul><ul><li>New units paid for themselves in just under six years. </li></ul></ul>
  5. 5. Reducing Power Costs <ul><li>Virtualization </li></ul><ul><ul><li>Use virtual servers where possible. </li></ul></ul><ul><ul><li>Reduces the number of servers which </li></ul></ul><ul><ul><ul><li>reduces waste and reduces power costs. </li></ul></ul></ul><ul><li>Variable Frequency Drives. </li></ul><ul><ul><li>These drives recognize decreased reduced loads and operate more efficiently. </li></ul></ul><ul><ul><li>1 watt of processor savings = 2.84 watts of overall savings </li></ul></ul>
  6. 6. Reducing Power Costs <ul><li>Hot Aisle/Cold Aisle </li></ul><ul><ul><li>Only the front of the rack is cooled. </li></ul></ul><ul><ul><li>Racks are arranged so hot air from one rack does not blow on another. </li></ul></ul><ul><ul><li>Racks must not allow hot air to pass through. </li></ul></ul><ul><li>Use a KVM switch so only one monitor is needed. </li></ul><ul><li>Allow desktop computers to hibernate or go into power saving mode when not used. </li></ul>
  7. 7. Newer Savings Ideas <ul><li>DC Data Center </li></ul><ul><ul><li>Convert AC to DC once resulting in savings due to a single more efficient conversion to DC. </li></ul></ul><ul><ul><li>Estimated savings of 15%. </li></ul></ul><ul><ul><li>Proof of Concept completed August 2008 by Sun Microsystems. </li></ul></ul><ul><ul><li>May only be a viable solution for larger data centers. </li></ul></ul>
  8. 8. Questions ??????????
  9. 9. <ul><ul><li>The End </li></ul></ul>
