About the NVIDIA Quantum-2 InfiniBand - 200Gb/s
The NVIDIA Quantum-2 InfiniBand QM9590 delivers 64 ports of NDR 400Gb/s QSFP112 connectivity in a compact 1U form factor, offering an aggregate switching capacity of 25.6Tb/s for next-generation data center fabrics. This high-density switch architecture enables network engineers and AI infrastructure teams to build scalable, low-latency interconnects without sacrificing port count or performance density.
Built on NVIDIA's Quantum-2 platform, the QM9590 combines sub-microsecond port-to-port latency with advanced in-network computing via NVIDIA SHARP v3, intelligent adaptive routing, and congestion control to optimize workload performance across distributed systems. The switch supports bidirectional 400Gb/s per port while maintaining backward compatibility with HDR 200Gb/s and EDR 100Gb/s deployments via splitter cables, protecting existing infrastructure investments. Full GPUDirect RDMA support, up to 16 virtual lanes per port, and redundant hot-swap power supplies with flexible airflow options ensure reliability and operational flexibility. Management is streamlined through NVIDIA UFM (Unified Fabric Manager), OpenSM, and REST API integration, enabling seamless fabric orchestration across enterprise environments.
Deployment Scenarios
- AI and machine learning clusters requiring ultra-low latency and high aggregate bandwidth for distributed training and inference workloads
- High-performance computing (HPC) environments leveraging in-network computing for efficient collective operations across thousands of nodes
- Large-scale storage networks demanding lossless, congestion-controlled fabric performance with dense port aggregation
- Cloud data centers consolidating multiple fabric tiers into unified NDR infrastructure with backward-compatible connectivity
- Real-time analytics platforms benefiting from sub-microsecond latency and NVIDIA SHARP v3 aggregation protocols
