Are Networks Burning Energy – Or Saving It?
A cloud-enabled world uses more networking. So, since we’re all moving to the cloud, now would be a very good time to look closely at communications. But the greening of networks is generating a lot of confusion right now. How much energy do cloud access networks need? If you listen to some people (Australia’s CEET institute, say) it’s about ten times as much as the data centres that power them. If you listen to others (green experts connected to Britain’s Intellect group), it’s only about ten percent.Some say networks dominate IT energy, while others have different ideas, says Peter Judge
