Ruijie RG-ETH 128 Supernode: Dual Architecture Scales AI Clusters to 1024 GPUs

Ruijie's RG-ETH 128 supernode uses a dual compute-switch architecture with 51.2 Tb/s switch chips to scale from 64 to 128 GPUs per cabinet via Host Tray decoupling, and up to 1024 GPUs across cabinets through 32×800G expansion ports, with a roadmap from 112G copper SerDes to 224G and LPO→NPO→CPO optical interconnects.
