The QM9700 switch system, based on NVIDIA Quantum-2, delivers 64 NDR 400Gb/s InfiniBand ports in a 1U standard chassis design, with an aggregate bidirectional throughput of 51.2 terabits (Tb/s) per switch and a landmark capacity of more than 665 billion packets per second (BPPS). NVIDIA Quantum-2 InfiniBand switches support the latest NDR technology to provide high throughput, in-network computing, intelligent acceleration engines, flexibility, and a robust architecture to meet the needs of high-performance computing (HPC), artificial intelligence, and hyperscale cloud infrastructure applications, while reducing costs and complexity.
