Play the recording: Meta 102.4T Ethernet Switch

  • Why: The switch platform that much of Meta's next-gen AI fabric story runs on — a concrete OCP hardware contribution on the newest merchant silicon, directly in the PM's physical switching interest.
  • What: IceCube, a 102.4T non-blocking Ethernet switch on the Broadcom TH6C ASIC running FBOSS: 2OU form factor, 64× OSFP-RHS user ports, liquid-cooled; IecPack is an ORv3-HPRv1 rack integrating eight IceCube blades plus servicing equipment for versatile switch roles (from abstract only).
  • How: Standard OCP open-hardware contribution model — merchant silicon + open NOS + open rack; engineering focus is reliability, power efficiency, and NPI velocity.
  • Where applicable: Meta-specific platform but fully OCP-documented; requires TH6C-class silicon and liquid-cooled racks. Pair with the integrated-optics talk for where this platform line is heading optically.
