Facebook continues to develop the design of various elements of server equipment and to freely distribute their design and control programs.
In June 2014, she handed over to the top-of-rack community the Wedge switch, software called Linux-based FBOSS for him, as well as the network architecture of the data center. And now the last missing element has been designed – the 6-pack modular switch.
The 6-pack platform uses Wedge as the basic building blocks. The platform contains 12 independent switching elements. Each of them can switch 1, 28 terabits / s and runs on its own operating system on a local server and is completely independent. Thus, it is possible to modify any part of the system without affecting the system level in the general non-blocking topology.
