NVIDIA Quantum-3 Q3400-RA InfiniBand Switch
The NVIDIA Quantum-3 family of fixed-configuration switches revolutionizes the performance, scalability, and efficiency of high-performance computing and AI infrastructures, enabling faster and more effective AI processing and computation. These switches are available in both 4U and 2U systems.
High-Density 800Gb/s Powerhouse
The NVIDIA Quantum-X800 Q3400-RA 4U switch leverages 200Gb/s-per-lane serializer/deserializer (SerDes) technology. It features 144 ports at 800Gb/s distributed across 72 Octal Small Form-Factor Pluggable (OSFP) cages. The switch’s high radix supports a two-level fat-tree topology capable of connecting up to 10,368 ConnectX-8 network interface cards (NICs) with minimal latency and optimal job locality. The Q3400-RA is air-cooled.
Q3200 2U: Dual Switches, Double Capacity
For integration with existing NDR or HDR infrastructures, the NVIDIA Quantum-X800 Q3200 2U air-cooled configuration switch is ideal. This system houses two independent switches within a single enclosure, together providing 72 ports at 800Gb/s (over 36 OSFP cages).
Dedicated Management Ports and UFM Support
Both the Q3400 and Q3200 switches include a dedicated InfiniBand in-band management port specifically for NVIDIA Unified Fabric Manager (UFM®) management, separated on the front panel from the other ports. This separation allows the full set of standard ports to be used for data network connectivity, simplifying port allocation and streamlining topology design. Additionally, NVIDIA Quantum-X800 switches feature optional router capabilities, facilitating the expansion of InfiniBand clusters to support a large scale of nodes located across multiple sites.
Advanced HPC and AI Workload Features
The 4U switch systems are ideal for HPC and AI workloads, leveraging the cutting-edge NVIDIA Scalable Hierarchical Aggregation and Reduction Protocol (SHARP)™, alongside enhanced adaptive routing and performance isolation technologies. With this powerful combination, they deliver unparalleled performance for handling the most demanding tasks in HPC and AI domains. The NVIDIA Quantum-3 switches are available with internal management capabilities.
Flexible Topology Support and Deployment Roles
As a rack-mounted InfiniBand solution, the NVIDIA Quantum-3 switches provide maximum flexibility for various network topologies. They support a wide range of configurations, including Fat Tree, Dragonfly+, multi-dimensional Torus, and more. In these setups, the 4U systems act as spines, while the 2U systems serve as leaves, complementing the overall network architecture.
