MQM9700-NS2R 400Gb/s InfiniBand Switch – 64 x QSFP56, 1U, C2P Airflow for Rear-to-Front Cooling

The MQM9700-NS2R is a managed member of the NVIDIA Quantum-2 series, built around the next-generation NDR (Next Data Rate) ASIC. It provides 64 QSFP56 ports running at 400Gb/s per port. This model features C2P (rear-to-front) airflow, making it suitable for data center racks with rear cold-aisle or front hot-aisle configurations. The switch is designed for top-of-rack leaf and spine connectivity, scaling from medium clusters to massive HPC and enterprise data center fabrics. Its integrated x86 dual-core CPU runs MLNX-OS, enabling comprehensive on-box management including integrated subnet manager for large-scale fabrics.

By offloading collective communication operations from the CPU to the switch network via SHARP technology, the MQM9700-NS2R dramatically reduces MPI operation time and frees valuable CPU resources for computation. This results in an order-of-magnitude improvement in application performance for parallel workloads.

The NVIDIA SHARP v3 technology embedded in the Quantum-2 ASIC enables the MQM9700-NS2R to perform collective operations such as MPI reductions directly within the network fabric. This eliminates multiple data traversals between endpoints, drastically reducing MPI operation time and freeing CPU cores for application computation. For fully populated fat-tree networks, partial reduction operations can complete in under three microseconds. This co-design approach accelerates communication frameworks and maximizes effective fabric bandwidth.

• Top-of-Rack Leaf Connectivity – Ideal for spine-leaf architectures in HPC and AI clusters with C2P cooling requirements.
• Medium to Extremely Large Clusters – Scales from a few hundred nodes to tens of thousands of nodes with integrated subnet management.
• Enterprise Data Centers – Supports high-performance storage, database, and compute workloads requiring low latency and high throughput.
• AI Training and Inference – SHARP v3 acceleration boosts NCCL and MPI-based distributed training performance.
• Cloud and Bare-Metal Infrastructures – Ideal for multi-tenant environments requiring high-bandwidth, low-latency network fabrics.

The MQM9700-NS2R is fully interoperable with NVIDIA Mellanox ConnectX adapters (NDR, HDR, EDR, FDR), LinkX cables, and transceivers. It is compliant with IBTA Specification 1.4 and 1.3, and supports backward compatibility to HDR (200Gb/s) and EDR (100Gb/s) technologies. The switch integrates with NVIDIA UFM (Unified Fabric Management) for advanced telemetry, AI-powered analytics, and proactive troubleshooting across the entire InfiniBand fabric.

Note: Verify airflow direction (P2C or C2P) matches your data center hot/cold aisle configuration before ordering. The NS2R model is specifically designed for rear-to-front airflow.

• Industry-leading performance – 51.2Tb/s throughput and ultra-low latency in a compact 1U chassis.
• Reduced IT costs – High port density (64 ports in 1U) reduces infrastructure footprint and operational expenses.
• Self-healing networking – InfiniBand fabric recovers from link failures 5,000* faster than software-based solutions.
• Flexible deployment – Backward compatible with HDR and EDR; supports modern topologies like Dragonfly+, SlimFly, and 6D torus.
• Enhanced telemetry – With UFM, gain real-time network insights and AI-driven analytics for proactive maintenance.
• Optimized cooling – C2P airflow matches specific data center configurations, ensuring efficient thermal management.
