Meta outlines open compute networking advances

Meta collaborated with Broadcom and Cisco to deploy two top-of-rack switches called Wedge 400 and 400C as it built out its data centers.

Meta outlined its next-generation network hardware and said its data centers have migrated to the Open Compute Project (OCP) Switch Abstraction Interface (SAI).

The move was announced at the Open Compute Project's annual conference. Meta, formerly known as Facebook, outlined the following on its open networking gear advances.

Wedge 400/400C top-of-rack switches. Meta collaborated with Broadcom and Cisco to deploy two top-of-rack switches called Wedge 400 and 400C. The Wedge 400 uses Broadcom's Tomahawk 3 ASIC and 400C uses Cisco's Silicon One. Celestica makes the networking equipment for Meta. Key points:

  • Both switches have more front panel port density for AI and machine learning applications.
  • The systems have 12.8 Tbps switching capacity, four times the capacity of the Wedge 100S.
  • Both switches have a field replaceable CPU system.

Meta's FBOSS network operating system for its network switches now is using OCP's SAI at scale. The move will allow Meta to work with more chip vendors.

200Gbps/400Gbps data center fabrics. Meta has deployed 200G optics in its data centers and plans to deploy 400G in the future. Meta developed two next-gen 200G fabric switches with the Minipack2, a modular network switch, and the Arista 7388X5 with Arista Networks.

Overall, Meta is making the argument that its open compute data center improvements will advance its plans to build out AI and its metaverse in a disaggregated model.
