Product Description
NVIDIA Quantum-2 MQM9700-NS2F 400Gb/s InfiniBand Switch
The NVIDIA Quantum-2 MQM9700-NS2F delivers 64 ports of 400Gb/s InfiniBand in a 1U chassis with front-to-rear (P2C) airflow, enabling extreme-scale AI and HPC clusters in standard data center environments. Featuring an on-board subnet manager, this fully managed switch supports up to 2,000 nodes out-of-the-box and integrates SHARPv3, RDMA, and adaptive routing for uncompromised performance.
Product Overview
The MQM9700-NS2F is a fully managed 400Gb/s InfiniBand fixed-configuration switch from the NVIDIA Quantum-2 series, featuring front-to-rear (P2C) 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.
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 – 32x 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)
- P2C (front-to-rear) 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-NS2F dramatically improves application performance while data traverses the fabric.
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

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 32x
- 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
- Standard P2C airflow: Matches most data center cooling designs with front-to-rear airflow
- 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.
What does P2C airflow mean?
P2C (power-to-connector, commonly referred to as front-to-rear) airflow means air enters from the power supply side and exits through the connector side. This is the standard airflow direction used in most data center cooling designs.
Can I use MQM9700-NS2F with existing HDR InfiniBand infrastructure?
Yes, the switch is backward compatible with HDR, EDR, and FDR speeds, allowing incremental upgrades.
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 (P2C) must match the installation environment
- 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 (P2C) matches your data center hot-aisle/cold-aisle layout
- Verify cluster size fits within the 2,000 node limit of the on-board subnet manager
- 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
