Detailed Product Description
NVIDIA Q3200-RA 72-Port 400Gb/s NDR InfiniBand Switch Dual System
Q3200-RA - 72-Port NDR 400Gb/s InfiniBand Dual-System Switch
Engineered for high-density AI and HPC clusters. The Q3200-RA integrates two independent 36-port Quantum-3 switches in a compact 2U air-cooled chassis.
28.8 Tb/s Total System Throughput
72 x 400Gb/s Ports (2 x 36 independent switches)
ASIC Technology: 2x NVIDIA Quantum-3 (NDR 400Gb/s)
Form Factor: 2U Rackmount • Air-cooled • C2P Airflow
Redundancy: 6x Hot-Swappable PSUs • 12x Fans
Product Overview
The NVIDIA Quantum-3 Q3200-RA is a dual-system InfiniBand switch platform, packing two independent 36-port NDR switches into a single 2U chassis. Leveraging NVIDIA's Quantum-3 ASIC, it delivers 400Gb/s per port with ultra-low latency. Ideal for building cost-effective leaf-spine fabrics, the Q3200-RA enables organizations to scale AI infrastructures without sacrificing port density or performance. Each of the two switch planes operates independently, offering physical redundancy in a compact form factor.
Key Features
  • Dual-System Architecture: Two independent 36-port NDR 400Gb/s switches in a single 2U chassis
  • High Throughput: 28.8 Tb/s aggregate system switching capacity
  • In-Network Computing: Full support for NVIDIA SHARPv3 (Scalable Hierarchical Aggregation and Reduction Protocol)
  • Advanced Fabric Management: Dedicated Fabric Management Port (FNM) for NVIDIA UFM telemetry and AI-driven orchestration
  • Reliability: Redundant, hot-swappable 6 PSUs and 12 fan units with Connector-to-Power (C2P) airflow
Technology & Performance
Each of the two switch modules inside the Q3200-RA is built on the NVIDIA Quantum-3 Switch ASIC, utilizing low-latency 50Gb/s SerDes (4 lanes per port). The switch features adaptive routing to avoid hot spots, congestion control algorithms, and performance isolation for multi-tenant AI clouds. It supports GPU-initiated communication and NVIDIA GPUDirect RDMA for accelerated compute jobs.
Optimized Topologies: Fat Tree (Leaf-Spine), Slim Fly, Dragonfly+

Frequently Asked Questions
Q: Is the Q3200-RA two separate switches or one logical switch?
A: It contains two physically independent 36-port 400Gb/s switches. They share the same chassis and power supplies but operate as separate fabric planes.
Q: Can I use the Q3200-RA in a spine role?
A: Yes. It is excellent for spine roles in smaller clusters or for partitioning larger fabrics. For very large spine layers, the Q3400-RA (144 ports) is recommended.
Q: What is the typical power consumption?
A: Approximately 1.5 kW with passive copper cables, up to 4 kW with active optical modules. Exact values depend on PSU configuration.
Q: Does the Q3200-RA support in-service software upgrade?
A: Yes, supported with redundant management modules. Please verify feature set in the specific MLNX-OS version.
Important Notice
This product is intended for professional data center deployment only. Use with NVIDIA-approved rail kits and power cords. Airflow direction (C2P) must match your rack hot/cold aisle configuration. Specifications, warranty terms, and software support may vary by region. Please consult your sales representative for definitive information before ordering.
