Product Overview
The NVIDIA Quantum-3 Q3400-RA is the industry's highest-density fixed-configuration InfiniBand switch, purpose-built for AI factories and exascale HPC systems. With 144 ports of 800Gb/s XDR connectivity in a 4U chassis, it eliminates the need for multiple spine tiers in large-scale leaf-spine architectures.
Each port operates at 800Gb/s bidirectionally, enabling a single Q3400-RA to connect up to 144 compute or storage nodes at wire speed. When paired with NVIDIA ConnectX-8 adapters, the switch delivers end-to-end 800Gb/s fabric performance.
Technology Deep Dive
The Q3400-RA is powered by the NVIDIA Quantum-3 ASIC, integrating 200Gb/s SerDes technology. Key innovations include:
- Adaptive Routing for congestion avoidance
- SHARPv3 in-network compute acceleration
- Performance isolation for multi-tenant AI clouds
- Optional router functionality for multi-site fabrics
Key Features
- 144 XDR Ports - 72 OSFP cages supporting 800Gb/s per port or 2x 400Gb/s per cage
- 115.2 Tb/s Throughput - Non-blocking switching capacity for massive parallel workloads
- SHARPv3 Support - In-network data reduction for collective operations, reducing job completion time
- Fabric Management Port - Dedicated FNM (OSFP) for NVIDIA UFM telemetry and out-of-band fabric orchestration
- Redundant Power - 8 hot-swappable 2000W PSUs with N+1 or N+N redundancy
- Ultra-Low Latency - Port-to-Port latency under 130ns

Frequently Asked Questions
Q: Is the Q3400-RA backward compatible with NDR (400Gb/s) or HDR (200Gb/s) equipment?
A: Yes. The Quantum-3 ASIC supports multi-speed operation. Ports can operate at 400Gb/s or 200Gb/s when connecting to legacy adapters or switches.
Q: Can I use the Q3400-RA as a leaf switch?
A: While possible, it is primarily optimized as a spine switch due to its high 144-port radix. For leaf roles, consider lower-density Quantum-3 models.
Q: What is the typical power draw at full load?
A: Approximately 2.9 kW with passive copper cables. This can increase to 6-7 kW depending on active optical module usage and temperature conditions.
Q: Does the Q3400-RA support in-service software upgrades?
A: Yes, with redundant management planes. Please check the specific MLNX-OS version for upgrade procedures.
Important Precautions
This product is for professional data center installation only. Use only NVIDIA-approved rail kits and power cords. The C2P airflow (connector-to-power) requires the cold aisle to face the port side. Warranty and support terms vary by region. Specifications may change without notice.
