Product Description
NVIDIA Q3200-RA 800Gb/s InfiniBand Switch
72-Port, 57.6 Tb/s Dual-Switch Chassis for AI Leaf & HPC Fabrics
72 XDR ports over 36 OSFP cages (2 * 36 per system)
57.6 Tb/s total switching capacity (2 * 28.8 Tb/s)
2U space-optimized chassis
4 * PSU redundant, hot-swappable
Dual ASIC two independent Quantum-3 switches in one chassis
Product Overview
The NVIDIA Q3200-RA is a 2U, dual-system InfiniBand switch platform powered by two independent NVIDIA Quantum-3 ASICs. It delivers 72 XDR ports at 800Gb/s across 36 OSFP cages — with each ASIC driving 36 ports (28.8 Tb/s). This unique architecture makes the Q3200-RA the ideal leaf switch for two-level fat-tree topologies, offering excellent density, power efficiency, and cost savings for AI training, HPC, and enterprise data center fabrics.
Key Features
Dual-System Chassis
Two independent 36-port Quantum-3 switches in a single 2U enclosure
800Gb/s XDR Ports
72 ports over 36 OSFP cages, supporting 400Gb/s (NDR) and 800Gb/s (XDR)
57.6 Tb/s Aggregate
Each switch provides 28.8 Tb/s non-blocking throughput
Redundant & Hot-Swappable
4 power supplies (C2P airflow) and 5 fans with N+1 redundancy
Technology
Quantum-3 ASIC (x2): Each Q3200-RA houses two NVIDIA Quantum-3 switch ASICs, each driving 36 ports at 800Gb/s. The dual-ASIC design allows the chassis to function as two independent switches or be managed as a single logical entity with UFM. Each ASIC supports SHARPv3 for in-network compute acceleration, plus advanced adaptive routing and congestion control.
Typical Deployments
- Leaf in two-level Fat-Tree: Pair with Q3400-RA spines to build cost-effective, high-radix fabrics
- Space-constrained AI clusters: 2U form factor delivers 72 ports with minimal rack footprint
- Mixed-speed environments: Seamlessly interconnect NDR and XDR endpoints with auto-negotiation
- Enterprise data centers: Ideal for manufacturing, finance, and research workloads requiring deterministic low latency

Advantages
- 2U density, 72 ports: Half the rack space of equivalent 4U solutions — lower TCO
- Dual ASIC flexibility: Operate as two independent switches or as unified fabric with UFM
- Investment protection: NDR/XDR mixed-speed support protects existing infrastructure
- SHARPv3 acceleration: Reduces AI training time by offloading collective operations

Frequently Asked Questions
What is the difference between Q3200-RA and Q3400-RA?
Q3200-RA is a 2U chassis with two independent switches (72 ports total) — ideal for leaf or smaller fabrics. Q3400-RA is a 4U chassis with 144 ports — ideal for spine roles in larger fabrics.
Can I use NDR optics with the Q3200-RA?
Yes. The ports support NDR (400Gb/s) and XDR (800Gb/s) optics and cables. Use 'connection-mode ndr' in NVOS for NDR links.
