- Rackable offers 40U racks which use energy-efficient DC power distribution within the rack.
- A large amount of power is wasted before it even touches the server when we have to go through a separate UPS and power distribution system that outputs AC which has to be converted back to DC again by the servers power supply.
- Sun’s energy-efficient BlackBox project is a data centre in a standard shipping container. What makes Sun’s BlackBox efficient is that it uses water as a heat exchange mechanism. Since water is about 7 times more efficient in heat exchange over air, it reduces the amount of power consumption used for cooling. You basically pump cold water in to the BlackBox and warm water comes out.
- SMEs with server rooms may need a little motivation to conserve power. These IT shops often use pedestal-based servers and a mixture of rack-mount servers and they often never see the electricity bill since that may be handled by departmental budgets. Business should seriously consider moving the power budget under the IT department and then they might get some motivation in containing energy costs through more efficient server rooms and desktop computers. Until then all the cries of green computing seems to fall upon deaf ears.
