High Light NVIDIA Quantum-2 InfiniBand switch 400Gb/s ，64-port NDR InfiniBand switch ，C2P airflow InfiniBand switch
NVIDIA Quantum-2 MQM9700-NS2R 400Gb/s InfiniBand Switch
MQM9700-NS2R 400Gb/s InfiniBand Switch - 64-port NDR managed switch with 51.2 Tb/s aggregate throughput, C2P (connector-to-power) airflow, and on-board subnet manager.
Product Overview
The MQM9700-NS2R is a fully managed 400Gb/s InfiniBand fixed-configuration switch from the NVIDIA Quantum-2 series, featuring connector-to-power (C2P) airflow and an on-board subnet manager for simplified deployment. It provides 32 OSFP ports, each capable of 400Gb/s (or 128 ports at 200Gb/s with port-split technology), and offers an aggregate bidirectional throughput of 51.2 Tb/s. With built-in management, SHARPv3 in-network computing, and advanced congestion control, the MQM9700-NS2R is ideal for medium to large-scale HPC, AI, and enterprise clusters where self-contained management and C2P airflow are required.
Key Features
  • 64 non-blocking 400Gb/s ports (32 OSFP connectors)
  • 51.2 Tb/s aggregate bidirectional throughput
  • Port-split technology: up to 128 ports @ 200Gb/s
  • SHARPv3 in-network computing – 32* AI acceleration
  • Sub-microsecond latency with adaptive routing
  • Self-healing fabric, QoS, and congestion control
  • On-board subnet manager – manages up to 2,000 nodes
  • 1+1 redundant hot-swappable power (200-240Vac)
  • C2P (connector-to-power) airflow – hot-swappable fans
  • MLNX-OS with CLI, WebUI, SNMP, and JSON interfaces
  • Backward compatible with HDR, EDR, and FDR
Technology: NVIDIA Quantum-2 Architecture
The Quantum-2 platform integrates the third-generation SHARP technology (SHARPv3), enabling in-network data aggregation that reduces data movement and accelerates AI training and HPC simulations. Combined with Remote Direct Memory Access (RDMA) and NVIDIA's Scalable Hierarchical Aggregation and Reduction Protocol, the MQM9700-NS2R dramatically improves application performance while data traverses the fabric. The on-board subnet manager provides full chassis management through CLI, WebUI, SNMP, or JSON interfaces, simplifying deployment and operations.
Typical Deployments
  • AI & Machine Learning clusters – large-scale GPU-accelerated training with SHARPv3
  • High-performance computing (HPC) – research simulations, weather modeling, and genomics
  • Data center spine-leaf – 400G InfiniBand fabrics for low-latency storage and compute
  • Enterprise & cloud – scalable, multi-tenant networks with on-board subnet management
  • Government & education – research labs and supercomputing centres

Orderable Part Number Description Airflow Management
MQM9700-NS2R 64-port 400Gb/s, 32 OSFP, managed, C2P airflow Connector-to-power (C2P) On-board subnet manager
MQM9700-NS2F 64-port 400Gb/s, managed, P2C airflow Front-to-rear (P2C) On-board subnet manager
MQM9790-NS2R 64-port 400Gb/s, unmanaged, C2P airflow Connector-to-power External (UFM)
MQM9790-NS2F 64-port 400Gb/s, unmanaged, P2C airflow Front-to-rear External (UFM)
The MQM9700-NS2R is recommended for deployments that require a self-contained management solution with on-board subnet manager, up to 2,000 nodes, and connector-to-power airflow. For larger fabrics or advanced UFM features, consider the externally managed QM9790 series.
Advantages
  • Unmatched density: 64 ports of 400G in 1U – reduces rack space and power per port.
  • In-network acceleration: SHARPv3 reduces data movement and accelerates AI/ML workloads up to 32*.
  • Flexible topologies: Supports Fat Tree, DragonFly+, Torus, and more for any cluster design.
  • Simplified management: On-board subnet manager enables out-of-the-box operation for up to 2,000 nodes, reducing setup time.
  • C2P airflow flexibility: Matches data centers with reverse airflow (connector-to-power) for optimal thermal management.
  • Investment protection: Backward compatible with HDR/EDR and future-proof for NDR200/400.
Frequently Asked Questions
What is the difference between MQM9700 and MQM9790?
MQM9700 includes an on-board subnet manager and is fully managed out-of-the-box for up to 2,000 nodes. MQM9790 is externally managed and leverages NVIDIA UFM for advanced fabric management, ideal for larger, more dynamic environments.
What does C2P airflow mean?
C2P (connector-to-power) airflow means air enters from the connector side and exits through the power supply side. This is the reverse of P2C (front-to-rear) and is used in data centers with specific hot-aisle/cold-aisle configurations.
Can I use MQM9700-NS2R with existing HDR InfiniBand infrastructure?
Yes, the switch is backward compatible with HDR, EDR, and FDR speeds, allowing incremental upgrades.
What cabling is supported?
OSFP connectors support passive/active copper and active fiber cables. Both optical modules and direct-attach cables can be used.
Does the switch support 200Gb/s operation?
Yes, using NVIDIA port-split technology, the MQM9700-NS2R can provide up to 128 ports at 200Gb/s.
Precautions
  • Ensure the operating ambient temperature remains between 0°C and 40°C.
  • Use only NVIDIA-qualified optical modules and cables for optimal performance.
  • Proper airflow direction (C2P) must match the installation environment – verify rack hot-aisle/cold-aisle orientation.
  • Do not block fan vents; maintain at least 5 cm clearance on both sides.
  • Power supply must meet 200-240Vac requirements; grounding is mandatory.

Buyer Checklist
  • Confirm airflow direction (C2P) matches your data center hot-aisle/cold-aisle layout – this is a reverse airflow model.
  • On-board subnet manager supports up to 2,000 nodes – verify cluster size fits within this scope.
  • Validate power input (200-240Vac) and redundancy requirements.
  • Check OSFP cable lengths and types (copper/fiber) for your rack distances.
  • Request extended warranty or on-site support if needed for mission-critical deployment.
