Mellanox MQM9790-NS2F 64-Port 400Gb/s InfiniBand Switch | Externally Managed for

Engineered for centralized, large-scale data center management, the MQM9790-NS2F is a 64-port 400Gb/s InfiniBand switch offering unparalleled fabric control and scalability. As a key component of the NVIDIA Quantum-2 platform, this high-performance network switch is designed to be seamlessly integrated into unified fabric management systems, enabling operators to efficiently provision, monitor, and optimize modern AI and HPC infrastructures.

• Centralized Fabric Management: Optimized for use with NVIDIA UFM® software, enabling holistic control of large-scale deployments.
• Maximized Port Density: Delivers 64 non-blocking 400Gb/s ports (51.2 Tb/s aggregate throughput) in a 1U form factor.
• In-Network Compute Acceleration: Incorporates 3rd-gen NVIDIA SHARPv3 technology to dramatically boost AI and HPC application performance.
• Topology Agnostic: Supports a wide array of fabric designs including Fat Tree, DragonFly+, and multi-dimensional Torus.
• High Reliability: Features hot-swappable, redundant power supplies and fan units for continuous operation.
• Operational Efficiency: Enables preventative troubleshooting and higher fabric utilization through advanced external management.

The MQM9790 series is built on the NVIDIA Quantum-2 platform, leveraging NDR 400G InfiniBand technology. Its architecture is designed to offload complex operations from servers into the network fabric, featuring:

• SHARPv3 (Scalable Hierarchical Aggregation and Reduction Protocol) for in-network computation, reducing data movement.
• Native support for Remote Direct Memory Access (RDMA) and adaptive routing.
• Port-Split Capability to configure 128 ports at 200Gb/s, providing deployment flexibility.
• Designed for integration with NVIDIA Unified Fabric Manager (UFM®) for end-to-end software-defined fabric management.

This externally managed network switch is ideal for large-scale, centrally controlled environments:

• Enterprise AI & ML Clusters: Building scalable, manageable fabrics for distributed training workloads.
• Hyperscale & Cloud Data Centers: Deploying as a managed fabric element under a single pane-of-glass.
• Large-Scale HPC Facilities: Where centralized monitoring, provisioning, and maintenance of thousands of nodes is critical.
• Research & Government Labs: Requiring robust, software-defined infrastructure for complex simulations.
• Managed Service Providers: Offering high-performance networking infrastructure with advanced oversight capabilities.

• Unified Fabric Control: Part of a software-defined ecosystem with NVIDIA UFM®, enabling automation, advanced analytics, and proactive health monitoring.
• Optimized for Scale: Removes the overhead of distributed subnet management, ideal for fabrics exceeding thousands of nodes.
• Full Quantum-2 Performance: Delivers the same industry-leading 400G density and SHARPv3 acceleration as the managed MQM9700 series.
• Reduced Operational Complexity: Centralized management streamlines provisioning, troubleshooting, and firmware updates across the entire fabric.
• Future-Proof Investment: Backward compatibility and support for evolving topology standards protect infrastructure investments.

Q: What is the primary difference between MQM9790-NS2F and MQM9700-NS2F?
A: The key difference is management. The MQM9790-NS2F lacks an on-board subnet manager and is designed to be controlled externally by NVIDIA UFM® software, making it ideal for large, centralized fabrics. The MQM9700-NS2F includes an internal subnet manager for standalone or smaller cluster use.

Q: Is NVIDIA UFM® software required to operate this switch?
A: For full functionality and fabric management, yes. The MQM9790 series is optimized for and typically deployed with NVIDIA UFM® or a compatible external fabric management platform.

Q: Can it connect to servers with older InfiniBand network card (NIC card)?
A: Absolutely. The switch supports backward compatibility with HDR (200G), EDR (100G), and FDR (56G) InfiniBand generations via appropriate cables or adapters.

Q: Does it support port splitting for 200Gb/s connectivity?
A: Yes. Using NVIDIA's port-split technology, each 400G port can be configured as two independent 200G ports, effectively offering up to 128 ports of 200Gb/s.

• Management Dependency: Ensure you have a licensed and configured NVIDIA UFM® instance or compatible management platform before deployment.
• Fabric Planning: Successful integration requires careful fabric design, including SM (Subnet Manager) placement and link configuration.
• Hardware Compatibility: Verify that your servers are equipped with compatible NDR or HDR/EDR InfiniBand network card (NIC card) and that cabling meets the 400G specification.
• Environmental Compliance: Install within specified operating temperature (0°C-40°C) and humidity ranges. Ensure the P2C airflow direction matches your data center's cooling scheme.
• Certification & Safety: The product carries CE, FCC, RoHS, and other key certifications. Installation should be performed by qualified personnel following data center best practices.
