When you’re an Internet juggernaut like Google, you can’t let simple things like the fact that a technology hasn’t been invented get in your way. Google has to transport a lot of data from Point A to Point B within their data center very quickly in order to work all of the magic they do that keeps the users coming back. The mortal world of networking has 1Gbps Ethernet networks, but that is the max for now. IEEE is working on developing both 40Gbps and 100Gbps standards, but it could be years before the standards are ratified and actual, functioning equipment hits the streets. Iconic organizations like Google can’t be sitting around, twiddling their thumbs waiting for standards to be ratified. The rumor is that their is evidence to suggest that Google has developed their own 10Gbps switches in-house for their data centers. Check out this Networkworld.com article for more about the story.
