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.
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
Government & education – research labs and supercomputing centres

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
