About the NVIDIA Quantum-3 InfiniBand - 800Gb/s (QM9800)
The NVIDIA Quantum-3 InfiniBand QM9800 delivers 64 ports of 400Gb/s NDR InfiniBand connectivity with 51.2Tb/s aggregate switching capacity in a compact 1U form factor. This next-generation switch provides exceptional port density for hyperscale data center deployments, enterprise AI clusters, and high-performance computing (HPC) environments requiring ultra-low latency and massive bandwidth aggregation. Network engineers and AI infrastructure teams select the QM9800 to eliminate fabric bottlenecks while maintaining sub-100ns cut-through latency across the entire switching architecture.
NVIDIA engineered the Quantum-3 series with intelligent in-network computing via SHARP v3, enabling real-time collective operations that offload compute from CPU cores. Hardware-based adaptive routing and enhanced congestion control optimize traffic patterns dynamically, while backward compatibility with HDR 200Gb/s endpoints protects existing infrastructure investments. The QM9800 supports multiple topologies—fat-tree, dragonfly, dragonfly+, and hypercube—giving data center architects flexibility in cluster design. NVIDIA Onyx (MLNX-OS) and NVIDIA Unified Fabric Manager (UFM) streamline provisioning, monitoring, and multi-switch orchestration across enterprise fabrics. Redundant hot-swappable power supplies and flexible airflow options ensure operational resilience in demanding rack environments. OSFP transceiver support accommodates AOC and DAC interconnects, simplifying cabling strategies for high-density deployments.
Typical Enterprise Deployment Scenarios
- AI model training clusters requiring sub-100ns latency and collective communication acceleration
- HPC simulation and scientific computing with dynamic traffic steering across 64 high-speed ports
- Enterprise data lakes and analytics platforms needing petabit-scale fabric throughput
- GPU-accelerated machine learning platforms with SHARP-enabled gradient aggregation and synchronization
- Hybrid cloud interconnect backbones supporting seamless failover and multi-fabric orchestration
