The QM9790 switch system based on NVIDIA Quantum-2 provides 64 NDR 400Gb/s InfiniBand ports in a 1U standard chassis design. A single switch delivers an aggregate bidirectional throughput of 51.2 terabits per second (Tb/s) and a signature capacity of over 66.5 billion packets per second (BPPS). Supporting the latest NDR technology, the NVIDIA Quantum-2 InfiniBand switch offers high throughput, in-network computing, intelligent acceleration engines, flexibility, and a robust architecture to meet the requirements of high-performance computing (HPC), artificial intelligence, and hyperscale cloud infrastructure applications while reducing cost and complexity.
As an ideal rack-mounted InfiniBand solution, the QM9790 NDR InfiniBand fixed-configuration switch supports multiple topologies including Fat Tree, SlimFly, DragonFly+, and multi-dimensional Torus, delivering exceptional flexibility.
NVIDIA Quantum-2 also offers backward compatibility with previous-generation products and broad support for software ecosystems.
Enhanced Management
The externally managed QM9790 switch leverages the advanced feature set of NVIDIA UFM® (Unified Fabric Manager), enabling data center operations teams to efficiently configure, monitor, manage, and maintain modern data center networks with proactive troubleshooting. This improves utilization and reduces overall operational expenses.
