NVIDIA Quantum-2 MQM9790-NS2F: 64-Port 400Gb/s InfiniBand Switch

Deliver Unprecedented Data Throughput for AI, HPC, and Hyperscale Environments

The NVIDIA Quantum-2 MQM9790-NS2F is a high-performance, fixed-configuration switch that sets a new standard for network density and speed. In a compact 1U form factor, it provides 64 ports of 400Gb/s InfiniBand, enabling massive scalability and ultra-low latency for the most demanding data-driven applications.

Key Facts at a Glance

Product Overview

Built on the revolutionary NVIDIA Quantum-2 platform, the MQM9790-NS2F is engineered to accelerate research and product development by providing unparalleled data capacity. It integrates third-generation NVIDIA SHARP™ In-Network Computing technology, enabling a 32X boost in AI acceleration power compared to prior generations. This switch is the ideal foundation for building extreme-scale, future-proof data center fabrics that require the highest performance and efficiency.

Key Features

• Unmatched Port Density: 64 non-blocking 400Gb/s ports in a 1U chassis, maximizing rack space utilization.
• NDR 400Gb/s Technology: Leverages the latest NVIDIA high-speed interconnect for extremely low latency and high bandwidth.
• In-Network Computing with SHARPv3: Offloads and accelerates collective communications, dramatically boosting AI and HPC application performance.
• Advanced Network Design: Supports flexible topologies including Fat Tree, DragonFly+, and multi-dimensional Torus for optimized network architecture.
• Adaptive Routing & Congestion Control: Ensures the highest effective throughput by dynamically managing network traffic.
• Port Split Technology: Enables operation as 128 ports of 200Gb/s for cost-effective network design.
• Self-Healing Network Capabilities: Enhances fabric resilience and reliability.

Advanced Technology: NVIDIA SHARPv3

The MQM9790-NS2F incorporates SHARPv3 (Scalable Hierarchical Aggregation and Reduction Protocol), a cornerstone of NVIDIA In-Network Computing. This technology allows computation to be performed within the network fabric itself as data moves between nodes. For AI training and HPC simulations, this reduces the amount of data that must be processed by endpoints, leading to significantly faster job completion times and virtually unlimited scalability for data aggregation tasks.

Typical Deployments

• AI and Machine Learning Fabrics: Ideal for large-scale AI clusters requiring massive parallel data exchange.
• High-Performance Computing (HPC): Suitable for research institutions running complex simulations and modeling.
• Hyperscale Data Centers: Used as a high-density spine or leaf switch to build efficient, scalable networks.
• Enterprise Core/Leaf: For large enterprises consolidating high-bandwidth workloads.
• GPU Cluster Networking: Directly connects to NVIDIA GPUs for optimized performance.

Compatibility & Ecosystem

The MQM9790-NS2F is fully backward compatible with previous InfiniBand generations (HDR, EDR, etc.), ensuring seamless integration into existing infrastructures. It is supported by the full NVIDIA software ecosystem, including:

• NVIDIA UFM (Unified Fabric Manager): For advanced provisioning, monitoring, and troubleshooting.
• MLNX-OS: Provides robust management capabilities via CLI, WebUI, and JSON.
• NVIDIA GPUDirect & RDMA: Enables direct data transfer between GPUs and storage, bypassing the CPU.
