OCP Summit 2026: Powering AI with Open Innovations in Scale-Up, Scale-Out, and Scale-Across Networks
What happened
IceCube (Nanosatellite) switch blades — 102.4-Tbps fabric switches that deliver 128×800G non-blocking switching capacity — sit inside each rack. Here’s some of what’s new: The 102.4T scale-out switch : Meta’s first liquid-cooled network rack (IcePack) and 102.4T switch blades (IceCube), designed to support high power density, deliver higher thermal efficiency, and enable gigawatt-scale AI clusters.
Open Switch Platform Architecture (OSPA) : a new OCP initiative, co-led by Meta, Microsoft, and Alibaba, that standardizes the switch platform layer — with specification v1.0 now submitted to OCP. The 102.4T Generation: Liquid-Cooled Networking at AI Scale As AI clusters grow to gigawatt scale, network switches must deliver dramatically more bandwidth while fitting within increasingly dense power and cooling envelopes.
IcePack is based on OCP’s ORV3-HPRv1 rack standard . IceCube comes in two variants , one built on Broadcom’s Tomahawk6C switch ASIC (a chip built for one specific job rather than general use) and one on NVIDIA Spectrum-6 Switch ASIC.
