High Light NVIDIA InfiniBand switch 144-port ，Mellanox XDR switch 800Gb/s ，AI network switch with warranty
NVIDIA Q3400-RA 144-Port 800Gb/s XDR InfiniBand Switch for AI
Product Overview
Built on the revolutionary NVIDIA Quantum-3 ASIC, the Q3400-RA is a high-radix, fixed-configuration switch designed for the most demanding AI and high-performance computing workloads. Leveraging 200Gb/s-per-lane SerDes technology, it scales two-level fat-tree topologies to connect up to 10,368 ConnectX-8 NICs with minimal latency. It serves as the ideal spine switch in large-scale leaf-spine architectures, ensuring optimal job locality and fast fabric performance.
Key Features
  • Massive Throughput: 144 ports of 800Gb/s XDR InfiniBand delivering 115.2 Tb/s switching capacity
  • High Port Density: 72 OSFP cages supporting 1x 800Gb/s or 2x 400Gb/s connections per cage
  • In-Network Computing: Supports NVIDIA Scalable Hierarchical Aggregation and Reduction Protocol (SHARP)
  • Advanced Fabric Management: Dedicated Fabric Management Port (FNM) for NVIDIA UFM telemetry and orchestration
  • Reliability: Redundant, hot-swappable 8 PSUs and 10 fan units with front-to-rear (C2P) airflow
Technology & Performance
The Q3400-RA utilizes the NVIDIA Quantum-3 Switch ASIC, integrating high-efficiency 200Gb/s SerDes. It features enhanced adaptive routing to avoid congestion and performance isolation to ensure predictable service for co-tenants. Optional router functionality allows extension of InfiniBand clusters across multiple sites. Optimized topologies include Fat Tree, Dragonfly+, and Multi-dimensional Torus.

Frequently Asked Questions
Q: Is the Q3400-RA compatible with NDR (400Gb/s) infrastructure?
A: Yes. The Quantum-3 supports multi-speed. It allows integration with existing NDR or HDR infrastructures, operating at 400Gb/s or lower speeds as needed.
Q: What is the typical power draw?
A: Approximately 2.9 kW with passive copper cables, up to 7 kW with active optical cables.
Q: Can this be used as a leaf switch?
A: It is primarily optimized as a Spine switch due to its high radix (144 ports), but it can be utilized in very dense leaf configurations.
Q: Does it include a Fabric Management Port?
A: Yes, a dedicated OSFP-based Fabric Management port is located on the front panel, separate from data ports.
This product is designed for controlled data center environments. Use only with approved rail kits (930-9SKIT-00L0-00B) for front-to-rear post support of 700-800mm. Power cords are sold separately. Specifications are subject to change without notice.
