Building a Hyper Energy Efficient Data Center Building a Hyper Energy Efficient Data Center Presentation Transcript

  • Building a Hyper Energy-Efficient Data Center Tom Raftery Blog: www.greenmonk.net Email: tom@redmonk.com
  • CIX • Cork Internet eXchange - CIX • Irish hyper energy-efficient data centre
  • CIX Vision • Energy-Efficient data centre • Why? • How?
  • Why? Climate change
  • Why? • DC running costs • Staffing - controllable • Connectivity - decreasing • Energy - increasing
  • 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!
  • Optimal DC environment
  • DC Energy Flow
  • Max Chiller Temp Max Temp
  • Minimise Humidification Minimise Humidification
  • Minimise Water mixing Water mixing
  • Minimise air mixing Air mixing
  • Typical DC
  • Cold Aisle Containment
  • Free Cooling Free Cooling
  • Free Cooling
  • Also • Dimplex heat exchange unit • Servers heat the CIX offices! • Low resistance, slow speed air paths
  • Geek Porn
  • Geek Porn
  • Also • NegaWatts • Charge customers
  • Geek Porn
  • Power • 10kv low impedence looped connection to the national grid • Using GE Super ECO UPS’s offering >98% efficiency
  • Geek Porn
  • ! 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
  • 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%
  • Conclusion • Simple steps taken • Large savings and USP
