High-density Quantum-2 NDR InfiniBand switch — 64 × 400 Gb/s OSFP ports, 51.2 Tb/s fabric, SHARP in-network acceleration, adaptive routing and redundant power/cooling — ideal for large-scale AI, HPC and data-center clusters.
NVIDIA / Mellanox Quantum-2 QM9790 (MQM9790-NS2R) Resources
The NVIDIA / Mellanox Quantum-2 QM9790 (MQM9790-NS2R) is a high-density NDR InfiniBand switch built on NVIDIA’s Quantum-2 switching ASIC. It delivers 400 Gb/s per port speeds across 64 non-blocking InfiniBand ports — making it one of the most powerful fixed-configuration switches available for next-generation networking fabrics.
High-Performance 400Gb/s NDR InfiniBand Switching
The QM9790-NS2R delivers cutting-edge 400Gb/s NDR InfiniBand connectivity across 64 OSFP-based ports, enabling a powerful 51.2 Tb/s switching capacity. Designed for scale-out AI, cloud, storage, and HPC infrastructures, it provides ultra-low-latency and deterministic performance for next-generation workloads.
In-Network Acceleration for AI, Cloud & HPC Fabrics
Powered by the NVIDIA Quantum-2 architecture, the QM9790-NS2R supports SHARP in-network compute acceleration, adaptive routing, congestion control, and full-fabric telemetry. These capabilities dramatically increase efficiency in large AI training clusters, hyperscale cloud environments, and HPC deployments.
High Availability and Data-Center Grade Reliability
The QM9790-NS2R ensures mission-critical density and reliability with hot-swappable PSUs and fans, flexible airflow orientation, and seamless integration with NVIDIA UFM for orchestration of massive InfiniBand fabrics.
