Industry-leading NDR 400Gb/s per port | 51.2 Tb/s aggregate throughput | SHARPv3 in-network computing | Ultra-low latency for AI & HPC fabrics
The NVIDIA Quantum-2 QM9700-NS2R is a fully managed 1U InfiniBand switch delivering an unprecedented 64 ports of 400Gb/s (NDR) non-blocking bandwidth. Designed for extreme-scale AI, scientific research, and high-performance computing (HPC) clusters, it enables massive scalability with 51.2 Tb/s aggregate bidirectional throughput and over 66.5 billion packets per second. Leveraging SHARPv3, adaptive routing, and RDMA, the QM9700-NS2R accelerates data movement and in-network computing for the most demanding workloads.
Built on the NVIDIA Quantum-2 platform, the QM9700 series redefines data center switching density and efficiency. The QM9700-NS2R (managed, C2P airflow) integrates 64 ports of 400Gb/s InfiniBand in a compact 1U chassis. It supports port-split technology to deliver up to 128 ports of 200Gb/s, offering flexible topologies like Fat Tree, DragonFly+, SlimFly, and multi-dimensional Torus. Backward compatibility with previous InfiniBand generations ensures smooth integration into existing infrastructure. With advanced telemetry, congestion control, and self-healing network capabilities, this switch maximizes application throughput while simplifying operations.
32 OSFP cages supporting 400G NDR or 128x200G via splitter cables, delivering the densest top-of-rack InfiniBand switch in 1U form factor.
Third-generation NVIDIA Scalable Hierarchical Aggregation and Reduction Protocol accelerates AI collective operations by up to 32X, reducing data movement and latency.
Remote Direct Memory Access (RDMA) and adaptive routing eliminate bottlenecks, while enhanced virtual lane mapping and congestion control maintain consistent performance.
Automatic failover, link-level retransmission, and advanced monitoring capabilities ensure non-disruptive operations for mission-critical workloads.
On-board subnet manager supports up to 2000 nodes out-of-the-box; full chassis management via CLI, WebUI, SNMP, and JSON/REST API.
Optimized for scalable, cost-effective cluster designs; double-density radix reduces network layers and lowers total cost of ownership.
The Quantum-2 platform integrates NVIDIA’s latest 400G SerDes technology, delivering 51.2 Tb/s of switching capacity. Key innovations include SHARPv3 in-network computing, which offloads collective operations from compute nodes, drastically improving AI training efficiency. The switch leverages Remote Direct Memory Access (RDMA) to bypass kernel overhead, achieving microsecond-scale latency. Adaptive routing dynamically distributes traffic across multiple paths to avoid hotspots, while enhanced quality of service (QoS) and virtual lane (VL) mapping guarantee bandwidth for critical applications. The QM9700-NS2R also incorporates advanced telemetry for real-time fabric monitoring and self-healing capabilities that automatically re-route traffic around link failures.
The QM9700-NS2R is fully interoperable with NVIDIA InfiniBand adapters (ConnectX-6, ConnectX-7, ConnectX-8), cables (active/passive copper, active fiber, optical modules), and previous FDR/EDR/HDR generations. It runs MLNX-OS with extensive API support for automation frameworks. Compatible with NVIDIA Unified Fabric Manager (UFM) for advanced monitoring, predictive analytics, and telemetry. The switch integrates seamlessly with major HPC schedulers and open network automation tools.
