NVIDIA Quantum-2 QM9700-NS2F Managed InfiniBand Switch 64-Port 400G NDR 51.2 Tb/s Throughput P2C Airflow

The NVIDIA Quantum-2 QM9700-NS2F is a fully managed 1U InfiniBand switch with power-to-connector (P2C) forward airflow, 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-NS2F 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-NS2F (managed, P2C forward 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.

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-NS2F also incorporates advanced telemetry for real-time fabric monitoring and self-healing capabilities that automatically re-route traffic around link failures.

• AI & Machine Learning Clusters: High-radix NDR switches enable massive GPU supercomputing pods with SHARPv3 accelerating NCCL collectives.
• HPC Research Centers: SlimFly or Fat Tree topologies connect thousands of nodes with ultra-low latency for weather simulation, genomics, and physics.
• Enterprise Data Centers: Consolidate East-West traffic with 400G spine-and-leaf architecture, reducing tier count and operational costs.
• Cloud & Hyperscale: DragonFly+ and multi-dimensional torus for maximum scalability with high bandwidth density per rack unit.
• Storage & IO Expansion: Connect high-performance storage systems using NVMe over Fabrics (NVMe-oF) via InfiniBand.

The QM9700-NS2F 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.

The QM9700-NS2F is ideal for customers requiring advanced on-box management (subnet manager) and power-to-connector (P2C) forward airflow. This airflow pattern draws cool air from the cold aisle through the power side and exhausts through the connector side, matching standard front-to-rear cooling designs. Verify your rack airflow strategy before ordering.

Starsurge provides end-to-end lifecycle support: from design consultation to deployment and post-sales maintenance. Our services include on-site installation guidance, RMA processing, firmware upgrade assistance, and customized cabling solutions. For high-volume projects, we offer dedicated account management and 24/7 technical escalation. The QM9700-NS2F ships with 1-year hardware warranty; extended support packages are available upon request.

• Ensure airflow direction (P2C forward for NS2F) matches your rack ventilation strategy — this model intakes from power side and exhausts through OSFP connector side.
• Use only approved NVIDIA OSFP modules or qualified passive/active copper/fiber cables for 400G performance.
• Installation should follow ESD precautions and be performed by qualified network personnel.
• Firmware updates must be executed using MLNX-OS guidelines to avoid interruption; schedule maintenance windows accordingly.
• Confirm that the input power is within 200–240V AC range with redundant feeds to maintain high availability.
