OCP Summit 2026: Powering AI with Open Innovations in Scale-Up, Scale-Out, and Scale-Across Networks
Meta's IcePack, IceCube, and MetaRoCE are reshaping how GPU clusters talk to the network — the infrastructure layer that determines whether your AI buildout scales.
Why it matters
Meta is open-sourcing next-generation AI networking hardware (liquid-cooled racks, 102.4T switches, custom transport protocol) designed to flatten the bottleneck between GPUs and storage at hyperscale. This is a buildout architecture play that directly competes with Nvidia's rack designs and sets an open standard for multi-plane fabric in large AI clusters.
The key facts
6 to knowIcePack: first liquid-cooled network rack from Meta
IceCube: 102.4T switch platform
Flattened Planar Fabric (FPF): multiplane backend scale-out fabric
MetaRoCE: open-source AI transport protocol
