Facebook is announcing today that it’s constructed another key hardware component to run the networks in its data centers exactly the way it wants to. Dubbed 6-pack, Facebook’s new homebrewed modular switch brings together connections to lots of Facebook-built Wedge switches, which in turn connect to servers sitting in racks inside Facebook’s server farms.
MOUNTAIN VIEW, Calif. — Hot Interconnects — Facebook is in production testing of its open Wedge switch design, and is on track to contribute the design and software to the Open Compute Project. Wedge is a “top-of-rack” (small, simple, low-cost) switch with 16 (or 32) 40Gbit/s Ethernet ports, designed to be the “first building block” of the “Facebook disaggregated switching technology,” according to a presentation here by Facebook Network Architect Yuval Bachar.
Facebook’s Open Compute Project (OCP) switch, code-named Wedge, likely won’t displace entrenched networking vendors like Cisco. But here’s why it will be revolutionary: It addresses the need for application-specific networking. Wedge uses commodity hardware in the form of a microserver plus an open-source operating system code-named FBOSS. Wedge and FBOSS give networking teams the flexibility to create custom switching platforms for specific uses, from both the hardware and software aspects.
