  • 8. Geek Porn
  • 9. CIX Vision • Energy-Efficient data centre • Why? • How?
  • 10. Why? Climate change
  • 11. Why? • DC running costs • Staffing - controllable • Connectivity - decreasing • Energy - increasing
  • 12. 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!
  • 13. Optimal DC environment
  • 14. DC Energy Flow Free Cooling
  • 15. DC Energy Flow Max Temp
  • 16. DC Energy Flow Minimise Humidification
  • 17. DC Energy Flow Water mixing
  • 18. DC Energy Flow Air mixing
  • 19. Typical DC
  • 20. Also
  • 21. Also
  • 22. Also • Low resistance, slow speed air paths • Dimplex heat exchange unit • Servers heat the CIX offices!
  • 23. Power • 10kv low impedence looped connection to the national grid • Using GE Super ECO UPS’s offering >98% efficiency
  • 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
  • 27. my 2 minute pitch • Social media consultant • Green IT evangelist • Blogger, podcaster, speaker • For hire!
