Creative ways of reducing your Carbon Footprint Tom Raftery Blog: cix.ie / tomrafteryit.net / lowerfootprint.com Podcast: www.podleaders.com Email: tom@tomrafteryit.net

CIX • Cork Internet eXchange - CIX • First hyper energy-efﬁcient data centre

Geek Porn

CIX Vision • Energy-Efﬁcient data centre • Why? • How?

Why? Climate change

Why? • DC running costs • Stafﬁng - controllable • Connectivity - decreasing • Energy - increasing

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 Free Cooling

DC Energy Flow Max Temp

DC Energy Flow Minimise Humidiﬁcation

DC Energy Flow Water mixing

DC Energy Flow Air mixing

Typical DC

Also • Low resistance, slow speed air paths • Dimplex heat exchange unit • Servers heat the CIX ofﬁces!

Power • 10kv low impedence looped connection to the national grid • Using GE Super ECO UPS’s offering >98% efﬁciency

! 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

my 2 minute pitch • Social media consultant • Green IT evangelist • Blogger, podcaster, speaker • For hire!
