$NVIDIA(NVDA.US) opened its Vera Rubin rack designs at the OCP Global Summit and lined up Meta, Google, and Cisco on the networking side
The company contributed Vera Rubin rack and compute tray designs through its MGX architecture. The updated MGX 1.2 spec supports racks up to 250kW with liquid cooling and fanless compute trays$Meta Platforms(META.US) is adopting NVIDIA Spectrum-6 Ethernet switches at 102.4Tb/s. With Spectrum-X Multiplane, the setup is meant to connect more than 100,000 GPUs across up to eight independent network pathsCisco $Cisco(CSCO.US) and $NVIDIA(NVDA.US) also announced USFP, a new pluggable optical module aimed at 400Gb/s per lane. They say that is 4x the bandwidth density and about 1.3x the power efficiency of today's 200Gb/s-per-lane optics, with capacity up to 12.8Tb/s in roughly the same footprintGoogle's Falcon Transport will ride on future ConnectX-10 SuperNICs and BlueField DPUs, and $NVIDIA(NVDA.US) also dropped open-source DSX tools for configuring networks and stress-testing GPU clustersNetworking is becoming as strategic as the GPU itself. Opening Vera Rubin while locking in $Meta Platforms(META.US), Google, and $Cisco(CSCO.US) is how $NVIDIA(NVDA.US) keeps the AI factory stack centered on its silicon even as hyperscalers push for more open infrastructureSource: StockMarket.News
