The Issue
The Journey: Coal to the Server
16.66 MW
Coal Energy
5-10% distribution loss
60% Lost through chimney
5 MW
to the
Data centre
0.35-0.5 MW
“Useful Server
Cycles”
1515-30% Server and
Storage utilisation
65% DC power Conversion and cooling loss

Green Cloud Computing
1. Cloud & VM Controls for servers
2. Increase/Decrease Cloud based on energy
Why Direct Current
• Why DC power?
• Reduces power conversions and transformations before the load
• Simpler system architecture – less complexity – more reliable
• Safe power distribution of less than 60VDC (48VDC)
