Building a Hyper Energy Efficient Data Center

  1. Building a Hyper Energy-Efficient Data Center Tom Raftery Blog: www.greenmonk.net Email: tom@redmonk.com
  2. CIX • Cork Internet eXchange - CIX • Irish hyper energy-efficient data centre
  3. CIX Vision • Energy-Efficient data centre • Why? • How?
  4. Why? Climate change
  5. Why? • DC running costs • Staffing - controllable • Connectivity - decreasing • Energy - increasing
  6. Why? DC Energy requirements • Rack of equipment typically used • 1.5 kW 8 years ago • 4.5 kW 5 years ago and • 15 kW in 2006!
  7. Optimal DC environment
  8. DC Energy Flow
  9. Max Chiller Temp Max Temp
  10. Minimise Humidification Minimise Humidification
  11. Minimise Water mixing Water mixing
  12. Minimise air mixing Air mixing
  13. Typical DC
  14. Cold Aisle Containment
  15. Free Cooling Free Cooling
  16. Free Cooling
  17. Also • Dimplex heat exchange unit • Servers heat the CIX offices! • Low resistance, slow speed air paths
  18. Geek Porn
  19. Geek Porn
  20. Also • NegaWatts • Charge customers
  21. Geek Porn
  22. Power • 10kv low impedence looped connection to the national grid • Using GE Super ECO UPS’s offering >98% efficiency
  23. Geek Porn
  24. ! Power o d Normal mode Bypass Static bypass supply o •Normal mode • The output voltage is newly generated, Rectifier Inverter independently from the input voltage Rectifie AC DC Load • Heat losses are present in rectifier and inverter r G DC AC supply Battery bank •Super Eco Mode • Load is supplied via the bypass Super Eco Mode • UPS rectifier keeps the battery charged Bypass • UPS inverter switched off supply Static bypass (no heat losses) Rectifier Inverter Transf. Rectifie AC DC Load r DC AC supply Battery bank
  25. End Result Standard DC CIX Chiller 33% 12% Humidifier 3% <1% CRAC 9% 4% IT Equipment 30% 80% PDU 5% 0.01% UPS 18% <2% Lighting 1% <1% Switch Gear 1% 1%
  26. Conclusion • Simple steps taken • Large savings and USP
