NVIDIA Quantum-2 QM9790-NS2F 400Gb/s InfiniBand Switch
64-Port NDR Managed Switch with 51.2 Tb/s Throughput | P2C Airflow for HPC & AI Data Centers
Product Overview
The NVIDIA Quantum-2 QM9790-NS2F belongs to the QM9700 series of fixed-configuration switches, setting a new benchmark for 400Gb/s InfiniBand performance. Housed in a compact 1U chassis, this managed switch delivers 64 non-blocking ports at 400Gb/s per port, translating to an aggregate bidirectional throughput of 51.2 terabits per second. Designed to meet extreme-scale AI and high-performance computing demands, the QM9790 integrates advanced in-network computing via NVIDIA SHARPv3 technology, adaptive routing, RDMA, and congestion control. The "NS2F" variant indicates power-to-connector (P2C) airflow, ideal for data centers requiring front-to-rear cooling.
Key Features
- 64 ports of 400Gb/s NDR: Full bisectional bandwidth in a 1U form factor; up to 128 ports at 200Gb/s via port-split technology
- 51.2 Tb/s aggregate throughput: + 66.5 billion packets per second (BPPS) capacity, zero packet loss
- NVIDIA SHARPv3: In-network computing reduces data movement, accelerating AI collective operations by up to 32x over prior generation
- On-Board Subnet Manager: Manages up to 2,000 nodes out of the box, simplifies fabric bring-up
- Advanced topology support: Fat Tree, SlimFly, DragonFly+, multi-dimensional Torus
- 1+1 redundant hot-swappable PSU: 80 PLUS Gold+ certified, front-to-rear (P2C) airflow
- Low latency & RDMA: Enables efficient GPU direct communication, ideal for AI training clusters
- Backward compatible: With previous InfiniBand generations (HDR, EDR)
Technology: In-Network Computing & SHARPv3
NVIDIA Quantum-2 platforms integrate the third generation of Scalable Hierarchical Aggregation and Reduction Protocol (SHARPv3). Unlike conventional networking where data must travel back and forth between compute and storage, SHARPv3 performs data reductions inside the network fabric. For AI and scientific workloads, this reduces the volume of data traversing the fabric, dramatically improving runtime performance. Combined with Remote Direct Memory Access (RDMA) and adaptive routing, the QM9790-NS2F eliminates congestion hot spots and extracts maximum throughput from GPU clusters.
Typical Deployments
- AI & Deep Learning Clusters: Large-scale GPU-accelerated environments (NVIDIA DGX SuperPOD, mainstream AI factories)
- High-Performance Computing (HPC): Research institutions, weather modeling, molecular dynamics, and computational fluid dynamics
- Hyperscale Data Centers: Efficient spine-leaf architectures using Fat Tree or DragonFly+ topologies
- Cloud & Enterprise Data Centers: High-frequency trading, big data analytics, and real-time simulation
- Higher Education & Research Labs: Scalable InfiniBand fabric for academic HPC clusters

Frequently Asked Questions
Q: What is the difference between QM9790-NS2F and QM9700-NS2F?
A: QM9790-NS2F is an unmanaged switch designed for environments where external fabric manager (NVIDIA UFM) handles control plane, while QM9700 includes an on-board subnet manager for standalone management up to 2000 nodes. Both offer identical port density and performance.
Q: Can I use QM9790-NS2F with 200G adapters?
A: Yes, using port-split technology, each 400G OSFP port can split into 2x200Gb/s, effectively providing up to 128 ports of 200G. Compatible with NVIDIA ConnectX-6 HDR adapters.
Q: Which optics/cables are officially compatible?
A: The switch supports OSFP connectors; passive/active copper cables, active fiber cables, and optical modules. We recommend NVIDIA-qualified cables for maximum reliability.
Precautions
- Ensure facility provides 200-240Vac power input - the switch does not support 110V
- Confirm airflow direction: P2C (NS2F) is front-to-rear (cold aisle intake)
- Operating altitude up to 3050m; do not exceed environmental temperature 40°C for sustained performance
- Use only compatible optical modules and cables to prevent damage to OSFP ports
