  1. 1. Cooling the Data Center Going Green MAY 2012 1
  2. 2. Why Go Green 2
  3. 3. Cooling the Data Center is the single greatestcontributed to CO2 emissions Overall eGA eGov Projects - Scope and Budget Statistics Key Findings Cooling Data Center • Cooling the Data Center accounts for over 63% of the power consumptions Budget Statistics Conversion • This number is even higher in our region as chiller Powering IT 63% of Data Center Energy efficiency starts to Consumption is for Cooling decrease at temperatures of 40°C and above Cooling IT Cooling IT • Cloud Computing will have greatly increase the need for computing power and 87% hence add greater strain to 93% the environment.

  4. 4. Cooling More Efficiently 4
  5. 5. Ambient Temperature  Ambient temperature is the average temperature in a data center Benchmark Study Overview  Easiest efficiency target and often Output the one that is most overlooked  Historically, data centers were operated with room temperatures in the 20°C to 22°C range  Todays server, storage and networking equipment have operating temperature variances that can easily exceed 35°C  Raising the ambient temperature by 0.5°C can save upward of 3% in energy costs  Data center operators should consider an average ambient temperature of 25°C GDIT 5
  6. 6. Hot and Cold Containment For the past 10 years or so, the idea of Benchmark Study Overview hot and cold aisle has become standard operating procedure Output Higher-density racks would often create hot spots on the floor Well-designed data centers have solved the hot spot issue by concentrating high-density racks into hot or cold containment aisles Heat leaving the racks is contained within the row via walls, and then is quickly channeled upward to the plenum Hot or cold containment zones have two distinct benefits:  Reduction of energy required to cool the data center floor through the elimination of heat leakage  Ability to fully utilize rack densities GDIT 6
  7. 7. Airflow The primary force for cooling in data centers is air, and the control of Benchmark Study Overview airflow can be a simple method of increasing cooling efficiencies with Output minimal expense. Equipment is installed in racks and the rack has open space, server administrators fail to install blanking panels Hot air from one server easily moves up the rack, contaminating (heating up) equipment above it A second and more basic method of improving airflow is to remove any blockages from under the floor itself Power and data cables over the years, is often one of the biggest impediments of good airflow and can restrict efficient cooling by as much as 30% GDIT 7
  8. 8. Airflow The primary force for cooling in data centers is air, and the control of Benchmark Study Overview airflow can be a simple method of increasing cooling efficiencies with minimal expense. Output Equipment is installed in racks and the rack has open space, server administrators fail to install blanking panels Hot air from one server easily moves up the rack, contaminating (heating up) equipment above it A second and more basic method of improving airflow is to remove any blockages from under the floor itself Power and data cables over the years, is often one of the biggest impediments of good airflow and can restrict efficient cooling by as much as 30% GDIT 8
  9. 9. Technology Refresh  Using technology refresh as a cooling Benchmark Study Overview solution may seem counterintuitive to many people, but it is a proven Output solution for many  Growth and a continuous drive toward virtualization while keeping existing equipment in "maintenance mode“  One reason is that the energy requirements of older servers, in some cases, are three to four times greater than new equipment.  In recent years, x86 server performance has been doubling with each new generation, while also becoming more energy-efficient. Doubling the performance and halving the power in the same space is a sound cost- saving concept GDIT 9
  10. 10. Renewable Cooling 10
  11. 11. Effects of Heat  In Bahrain the temperatures rise to over 50CTemperature  Humidity in the summer months reaches an increase average of 90% Humidity  At such temperature and humidity the air- Cooling conditioning units need to be sized much bigger Efficiency and will work less efficiently Decrease Energy  This increase in size and decrease in efficiency will lead to a greater power consumptionconsumption Retention GDIT
  12. 12. Propane-powered refrigeratorThese refrigerators are interestingbecause they have no moving partsand use gas or propane as theirprimary energy source. Also, theyuse heat to produce the cold insidethe refrigerator.GDIT
  13. 13. Why not use the Sun’s energy against its self and convert Solar Heat into Solar Cooling? 13
  14. 14. GDIT
  15. 15. Using the Sun’s Energy• Driving energy for absorption chillers is taken from renewable energy and thus CO2-neutral.• Reduction of electrical consumption and thus of cooling-related CO2 emissions.• Facilitates the use of renewable cooling for existing properties.• Absorption chillers complements air-cooled compression chillers in arid climate zones affected by a rise in ambient temperatures: since the efficiency of air-cooled compression chillers is drastically reduced by ambient temperatures above 40°C.• The use of ICE storage systems for use at night to cool the data center will enable 24 hour free cooling. This is achieved by connecting the ICE storage system to the absorption chiller and using the excess cold water to produce ICE and store the ICE for when its needed. GDIT
  16. 16. Bottom Line Each of these techniques have been proven again and again by large and small data centers worldwide. While some solutions may not be right for your environment, implementation of any of these solutions can help reduce cooling costs and, therefore, reduce month-to-month operating costs while freeing up power and cooling resources for other workloads.
