  • Issues and opportunities around energy, the environment and sustainability, impact every individual and every business. Faced with the issue of an energy efficient data center, businesses are looking for ways to optimize their computing environments to the benefit of their bottom line and our planet. A green IT strategy has become a necessity. By combining hardware, software and services offerings, many companies are willing to help clients improve service, better manage risk, and resolve resource constraints-all while reducing overall energy costs.These services could include the optimization of:Increased server utilization. Reduced system management complexity. Lower power and cooling costs. Reduced demand for data center floor space. Lower IT total cost of ownership.


  • 1. Eco-Efficiency within Data Center designs a Middle Eastern perspective

  • 2. The Green Initiative
    "Today's corporate leaders are already very conscious of using green practices when considering new facilities, and they expect “Green buildings” to have an increasing impact in the future”
    Source: Siemens Building Technologies
  • 3. The Middle East
  • 4. Introduction
    What makes the Middle East different to the rest of the world?
    • Booming development across the region
    • 5. Abundance of Energy
    • 6. An active awareness for the need of global environmental protection – The attempt at becoming a good corporate citizen on the Global scene.
    Therefore creating the need for
    Energy Efficient Data Centers
  • 7. Agenda
    • What it means to be “Green”
    • 8. Data Center Efficiency
    • 9. Structured Cabling within DCs
    • 10. Thermal Management and cooling
    • 11. The role of Modularity within DC Designs
    • 12. Environmental monitoring
    • 13. Integrated Delivery / Supply services
    • 14. Questions
  • What it Means to Be “Green”
    Materials Reduction
    Energy Efficiency
    Increased Recycling
    Packaging Reduction
    Reduction of Hazardous Material

  • 15. Data Center Infrastructure Efficiency (DCIE)
    Power Usage Effectiveness (PUE)
  • 16. Structured Cabling
    • High density applications –
    • 17. space in Data Centers are a premium
    • 18. anything up from $460 to $1000 per sq ft
    • 19. the more space, the more cooling
    • 20. Pre-terminated copper and fiber solutions
    • 21. Lab manufactured – less wastage
    • 22. Buy-back and recycling of DC material
    • 23. Abatement – process of removal of old unused cabling. Studies have shown that airflow can be restricted up to 70% by unused cabling.
  • Structured Cabling
    • Placement of cabling to not interfere with cooling – the need for effective cable management:
    • 24. Explore cable management options to maximize density and route cabling away from equipment cooling areas–
    • 25. Use angled patch panels and vertical patching channels - Angled panels reduce/eliminate need for horizontal cable management, saving rack/cabinet space
    • 26. RoHS compliant products
  • Thermal Management and Cooling
  • 27. Typical Data Center Cooling Design:
    Hot Aisle & Cold Aisle
    (Chaos Design)
    • Mixture of Hot and Cold air
    • 28. Hot air recycles back into equipment – increasing heat
    • 29. More energy required to remove hot air and from cold air
  • Typical Data Center Cooling Design:
  • 30. Effective Containment of Hot and Cold Air
    (Prevention of hot and cold air mixing at any stage)
    • Hot air containment via return air plenum (ceiling voids) – passive cooling
    • 31. Hot or Cold aisle containment made possible with mechanical construction (data cube)
  • Containment of Hot / Cold air
    Hot Air Return Plenum (chimney)
    • Cold air enters cabinet through front and / or bottom of cabinet
    • 32. Hot air escapes through top of cabinet into separate plenum (ceiling) where the air is moved back to the CRAC unit.
  • Containment through hot air return plenum
    • No liquid / plumbing required – complete cabinet manufacturing
    • 33. Effective 2kW to 30kW
    • 34. Reduces operational costs by isolating hot exhaust air from cool supply air, maximizing cooling unit efficiencies
    • 35. Reduces energy consumption by providing 100% HVAC utilization of cool supply air
    • 36. Reduces cooling costs up to 40%
    • 37. Allows for raised set points (thermostat setting) on cooling units, lowering energy consumption and costs
    • 38. Permits for higher heat densities/power densities based on maximizing cooling efficiency
    • 39. There are no moving parts that require redundant systems

  • 40. Passive cooling racks with chimney designed to extract hot air into hot air return plenum.
  • 41. Containment of Hot / Cold air
    Aisle Containment
  • 42. Aisle Containment
  • 43. Aisle Containment of Hot / Cold air
    • Increased and Predictable Cooling capacity
    • 44. Better cooling performance
    • 45. Increased Cooling efficiency - Lower air flows required, extending the life and efficiency of the CRAC. When air-conditioning units are operated at full load, their efficiency decreases. At a speed of 50% or less, CRAC units can be operated more energy efficiently.
    • 46. Eliminates hot spots in the aisles
    • 47. Scalability with the aid of additional cooling components (eg in-row cooling units)
    • 48. Additional Security within contained environment
  • The role of Modularity within DC Designs
    • A Design Philosophy – Modularity within all components – don’t over compensate
    • 49. Modularity has become the Building Blocks of a scalable, cost-effective and energy efficient Data Center
    • 50. Modular designs within:
    • 51. Power supply and distribution
    • 52. Cooling
    • 53. Redundancy
    • 54. Fully loaded Modular Data Centers – plug and play containers – expand when require. Examples SUN, Microsoft, Google, IBM.
  • Environmental Monitoring
    • Not just an alarm system
    • 55. Monitor and indicate on power utilisation
    • 56. Intelligent software monitors integration between power utilisation and controls CRAC units in accordance
    • 57. Can indicate placement of new equipment within under-utilised cabinets
  • Integrated Delivery / Supply Services
    • Reduction of materials and wastage on site
    • 58. Recycling of materials plastics / paper etc
    • 59. Minimise freight packaging
    • 60. Quicker deployment on site – reduction of man hours and time wasted on site
    • 61. LEED credits
  • Integrated Supply Chain Services
    • Efficient Materials and waste management
