It's no secret that streamlining network architectures not only improves the flow of data, but can produce significant savings in energy as well.
In this article, Extreme Network's Harpreet Chadha offers three ways to reconfigure the typical enterprise network for those of you interested in seeing more green, both the environmental and monetary kind.
In a nutshell, she recommends the latest generation of Ethernet switching technology, preferably with some sort of power-down function to lessen the draw during idle periods. And with newer, faster switches, such as 10 GbE, many enterprises may be able to shut down the aggregation layer of their networks and simply jump directly from edge to core. Finally, it probably pays to check out new generations of intelligent software designed to manage power consumption at the network edge.
It's probably true that none of these fixes will produce the kinds of results being seen with server and storage consolidation, but if system refresh cycles are coming due anyway, it certainly pays to upgrade with power efficiency in mind.
