Rockley demos a silicon photonics switch prototype
Part 1: Rockley Photonics
Rockley Photonics has made a prototype switch to help grow the number of servers that can be linked in a data centre. The issue with interconnection networks inside a data centre is that they do not scale linearly as more servers are added.
“If you double the number of servers connected in a mega data centre, you don’t just double the complexity of the network, it goes up exponentially,” explains Andrew Rickman, co-founder, chairman and CEO at Rockley Photonics. “That is the problem we are addressing.”
By 2017 and 2018, it will still be possible to build the networks that large-scale data centre network operators require, says Rickman, but at an ever increasing cost and with a growing power consumption. “The basic principles of what they are doing needs to be rethought,” he says.
