Facebook is on a mission to make the fiber optic networking inside of its data centers go from 40G to 100G. Its Wedge 100 top-of-rack network switch (basically, the device that connects all the servers in a rack to the wider data center network) was already accepted into the Open Compute Project and today, the company lifted the veil of Backpack, its next-gen 100G switch platform for connecting all the racks inside of the data center together.
As Omar Baldonado, Facebook’s Director of Software Engineering for Networking, told me, the company is looking at this faster networking technology for a number of reasons, but it’s mostly driven by the need to be able to support more live and recorded video, as well as 360 photos and video. Facebook’s own internal data center traffic also continues to increase as developers look at new ways to gather analytics and use that data to improve the user experience.
100G, however, is still very much at the leading edge of high-speed networking. Facebook is obviously not the only company working on this. LinkedIn, for example, has also recently talked about how it plans to take its data center in Oregon to 100G in the future. Unlike others, though, Facebook is committed to opening up the designs of its servers and networking technology — and the software that power them — for the rest of the industry.
Facebook plans to contribute the design of the new Backpack switches to the Open Compute Poject as well. It’s currently starting to slowly roll out the Backpack to its data centers as it goes through its internal testing procedures. via
