- 9. CIX Vision • Energy-Efficient data centre • Why? • How?
- 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!
- 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!
