Mellanox Quantum-2 MQM9790 64-port Non-blocking Unmanaged NDR 400Gb/s InfiniBand Switch - Part ID: MQM9790-NS2R

As high-performance computing (HPC) and artificial intelligence (AI) applications become more complex, the demand for the most advanced high-speed networking is critical for extreme-scale systems. NVIDIA Quantum-2 is the industry-leading switch platform in power and density, with NDR 400 gigabit per second (Gb/s) InfiniBand throughput that provides AI developers and scientific researchers with the highest networking performance available to take on the world’s most challenging problems.

The NVIDIA Quantum-2-based QM9700 and QM9790 switch systems deliver an unprecedented 64 ports of 400Gb/s InfiniBand per port in a 1U standard chassis design. A single switch carries an aggregated bidirectional throughput of 51.2 terabits per second (Tb/s), with a landmark of more than 66.5 billion packets per second (BPPS) capacity. Supporting the latest NVIDIA high-speed interconnect 400Gb/s technology, NVIDIA Quantum-2 brings a high-speed, extremely low-latency and scalable solution that incorporates state-of-the-art technologies such as Remote Direct Memory Access (RDMA), adaptive routing, and NVIDIA Scalable Hierarchical Aggregation and Reduction Protocol (SHARP)™. Unlike any other networking solution, NVIDIA InfiniBand provides self-healing network capabilities, as well as quality of service (QoS), enhanced virtual lane (VL) mapping, and congestion control to provide the highest overall application throughput. As an ideal rack-mounted InfiniBand solution, the QM9700 and QM9790 400Gb/s InfiniBand fixed-configuration switches allow maximum flexibility, as they enable a variety of topologies, including Fat Tree, SlimFly, DragonFly+, multi-dimensional Torus, and more. They’re also backwards compatible to previous generations and include expansive software ecosystem support.
