Facebook Engineering: Introducing 6-pack, the open hardware modular switch

The “6-pack” platform is the core of our new fabric, and it uses “Wedge” [a custom built network switch] as its basic building block. It is a full mesh non-blocking two-stage switch that includes 12 independent switching elements. Each independent element can switch 1.28Tbps. We have two configurations: One configuration exposes 16x40GE ports to the front and 640G (16x40GE) to the back, and the other is used for aggregation and exposes all 1.28T to the back.
