Description

NVIDIA Quantum-2 QM9790 400Gb/s InfiniBand Switch

The NVIDIA QM9790 400Gb/s InfiniBand Switch is a high-performance, externally managed networking solution designed for AI infrastructure, high-performance computing (HPC), and enterprise data centres. Built on NVIDIA Quantum-2 technology, it delivers high-bandwidth, low-latency connectivity for demanding distributed computing workloads.

The NVIDIA Quantum-2 QM9790 is a high-performance, externally managed InfiniBand switch designed for AI infrastructure, high-performance computing (HPC), scientific research, and large-scale data centres. Built on NVIDIA Quantum-2 technology, it provides high-bandwidth, low-latency connectivity for demanding distributed computing workloads.

With 64 × 400Gb/s NDR InfiniBand ports and 51.2 Tb/s of aggregate bidirectional throughput, the QM9790 is designed to connect GPU servers, compute nodes, and high-performance storage systems in scalable computing fabrics.

Key Features

• 64 × 400Gb/s NDR InfiniBand ports: High-speed connectivity for demanding AI and HPC applications through 32 physical OSFP connectors.
• 51.2 Tb/s aggregate bidirectional throughput: Supports high-volume traffic across large compute clusters.
• Externally managed architecture: Designed for management through an external fabric-management solution, such as NVIDIA Unified Fabric Manager (UFM).
• Adaptive routing and congestion control: Networking capabilities designed to help maintain efficient traffic flow under heavy workloads.
• Remote Direct Memory Access (RDMA): Supports low-latency data movement for compatible systems and applications.
• NVIDIA SHARP technology: Supports in-network computing and collective communication acceleration in compatible deployments.
• Compact 1U rack-mount design: Provides high port density while conserving rack space.
• Redundant power and cooling: Documented AC configurations include two replaceable power supplies and replaceable fan modules.

Typical Applications

• AI training and GPU computing clusters
• High-performance computing and supercomputing
• Scientific research and simulation
• High-speed storage and data-intensive workloads
• Large-scale InfiniBand data-centre fabrics

Configuration and Ordering

The QM9790 is an externally managed switch and should not be confused with the internally managed QM9700. Confirm the exact NVIDIA part number, airflow direction, power requirements, management software compatibility, and included accessories before ordering.

Compatible InfiniBand cables and transceivers must be selected for the intended network speed, distance, and connected equipment.
