Nvidia™ Quantum InfiniBand Switches

As computing requirements continue to grow exponentially, NVIDIA™ Quantum InfiniBand, the world’s only fully off-loadable, in-network computing platform, provides the dramatic leap in performance required to enable HPC, AI and hyperscale cloud infrastructures achieve unmatched performance with less cost and complexity.

The NVIDIA™ ConnectX-7 NDR 400Gb/s InfiniBand host channel adapter (HCA) provides the highest networking performance available to take on the world’s most challenging workloads. The ConnectX-7 InfiniBand adapter provides ultra-low latency, 400Gb/s throughput, and innovative NVIDIA™ In-Network Computing engines to provide additional acceleration to deliver the scalability and feature-rich technology needed for supercomputers, artificial intelligence, and hyperscale cloud data centers.

The NVIDIA™ Quantum-2 modular switches provide scalable port configurations from 512 ports to 2,048 ports of 400Gb/s InfiniBand (or 4,096 ports of 200Gb/s) with a total bi-directional throughput of 1.64 petabits per second - 5x over the previous-generation InfiniBand modular switch series, enabling users to run larger workloads with fewer constraints. The 2,048-port switch provides an unprecedented 6.5x greater scalability over the previous generation, with the ability to connect more than a million nodes with just 3 hops using a DragonFly+ network topology.

Offloading operations is crucial for AI workloads. The third-generation NVIDIA™ SHARP technology allows deep learning training operations to be offloaded and accelerated by the Quantum-2 InfiniBand network, resulting in 32x higher AI acceleration power. When combined with NVIDIA™ Magnum IO™ software stack, it provides out-of-the-box accelerated scientific computing.
