NVIDIA Quantum-2 QM9700 Series Switches

Scaling Out Data Centers with NDR 400G InfiniBand Smart Switches

The NVIDIA Quantum-2-based QM9700 and QM9790 switch systems deliver an unprecedented 64 ports of NDR 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 NDR technology, NVIDIA Quantum-2 brings a highspeed, 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 NDR 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.

The Era of Data-Driven Computing

Complex research demands ultra-fast processing of high-resolution simulations, extreme-size datasets, and complex, highly parallelized algorithms that need to exchange information in real time. The QM9700 NDR InfiniBand switches extend NVIDIA In-Network Computing technologies and introduce the third generation of NVIDIA SHARP technology, SHARPv3. Creating virtually unlimited scalability for large data aggregation through the network, SHARPv3 enables support for up to 64 parallel flows—32X higher AI acceleration power compared to the previous generation.

World-Class InfiniBand Performance

In-Network Computing

NVIDIA Mellanox Scalable Hierarchical Aggregation and Reduction Protocol (SHARP)™ In-Network Computing technology offloads collective communication operations from the CPU to the switch network, improving application performance by an order of magnitude.

Self-Healing Computing

NVIDIA Mellanox InfiniBand with self-healing networking capabilities overcomes link failures and achieves network recovery 5,000X faster than any software-based solution—enhancing system performance, scalability, and network utilization.

UFM Management

NVIDIA Mellanox Unified Fabric Management (UFM®) platforms combine enhanced, real-time network telemetry with AI-powered cyber intelligence and analytics to realize higher utilization of fabric resources and a competitive advantage, while reducing OPEX.
