#Facebook tor switch software#
FBOSS is still the software that binds together our data centers.We developed HGRID as the evolution of Fabric Aggregator to handle the doubling of buildings per region.We are contributing both Minipack and the Arista 7368X4 to OCP, and both run FBOSS. In addition to Minipack, we also jointly developed Arista Networks’ 7368X4 switch. More important, it is built to be modular and flexible so it can serve multiple roles in these new topologies and support the ongoing evolution of our network over the next several years. We designed a brand-new building block switch, Minipack, that consumes 50 percent less power and space than its predecessor.We developed F16 using mature, readily available 100G CWDM4-OCP, which in essence gives us the same desired 4x capacity increase as 400G link speeds, but with 100G optics. F16 is also more scalable and simpler to operate and evolve, so we are better equipped for the next few years. In the network, we developed F16, a next-generation data center fabric design that has 4x the capacity of our previous design.In this post, we’ll share the story of this transformation over the last two years: Even as the demands increase, we are bound by hard physical constraints of power and optics supply availability.īecause of these dual pressures of increasing demand and physical constraints, we decided to rethink and transform our data center network from top to bottom, from topologies to the fundamental building blocks used within them. We have grown from a handful of regions to 15 locations around the world. Our data center fabrics now support more than 2.6 billion people on a family of video-enabled, real-time apps and a rapidly expanding, extremely demanding set of internal services. Most recently, we announced last year our distributed network system, Fabric Aggregator. Since then, we have openly shared our journey of building our own switches, writing FBOSS (our own network operating system) and continuing to scale out various aspects of the network.
When we first shared details of our data center fabric, we were supporting 1.35 billion people on one app.
