Характер продукции
Engineered for extreme-scale AI and HPC environments where external fabric management is preferred. The MQM9790-NS2R delivers 64 non-blocking ports of 400Gb/s InfiniBand in a compact 1U chassis with connector-to-power (C2P) reverse airflow, enabling flexible topologies and SHARPv3 in-network computing while relying on external Subnet Managers such as NVIDIA UFM or OpenSM.
Hong Kong Starsurge Group presents the NVIDIA Quantum-2 MQM9790-NS2R — a high-performance, unmanaged 400Gb/s InfiniBand switch with reverse airflow (connector-to-power). As part of the QM9700 series, this switch provides 32 OSFP ports supporting 64× 400Gb/s connections (or up to 128 ports at 200Gb/s via port-split technology). With a landmark 51.2 terabits per second bidirectional throughput and over 66.5 billion packets per second capacity, the MQM9790-NS2R is designed for customers who require external Subnet Manager control (e.g., NVIDIA UFM) for advanced telemetry, monitoring, and large-scale fabric orchestration.
- Unprecedented Port Density: 64 ports of 400Gb/s NDR InfiniBand in 1U, non-blocking architecture.
- Double-Density 200Gb/s Mode: Supports up to 128 ports of 200Gb/s using NVIDIA port-split technology, reducing TCO for leaf-spine topologies.
- External Subnet Manager Ready: Designed for use with NVIDIA UFM (Unified Fabric Manager), OpenSM, or other external Subnet Managers — ideal for large-scale, centrally managed fabrics.
- In-Network Computing: SHARPv3 (Scalable Hierarchical Aggregation and Reduction Protocol) delivers 32x higher AI acceleration compared to prior generation.
- Advanced Fabric Services: RDMA, adaptive routing, congestion control, enhanced VL mapping, and self-healing network capabilities.
- Reverse Airflow (C2P): Connector-to-Power airflow direction ideal for data center layouts with cold aisle on the port side.
- Redundancy & Reliability: 1+1 redundant hot-swappable power supplies, hot-swappable fan units.
- Backward Compatible: Supports previous InfiniBand generations (HDR, EDR, FDR).
Built on the NVIDIA Quantum-2 ASIC, the MQM9790-NS2R leverages state-of-the-art 400Gb/s SerDes technology. It incorporates Remote Direct Memory Access (RDMA) for low CPU overhead and high throughput, adaptive routing to avoid fabric hotspots, and NVIDIA SHARPv3 for in-network reductions, dramatically accelerating collective operations in MPI and AI frameworks. Without an onboard Subnet Manager, this model offloads fabric management to external controllers, enabling centralized policy enforcement and deeper telemetry when paired with NVIDIA UFM.
With support for multiple topologies — including Fat Tree, SlimFly, DragonFly+, and multi-dimensional Torus — the MQM9790-NS2R enables architects to build cost-effective, highly resilient networks for next-generation supercomputing while maintaining centralized management.
- AI & Machine Learning Clusters: High-speed GPU interconnects for large language model training with centralized UFM management.
- High-Performance Computing (HPC): Research simulations, weather modeling, genomics requiring external fabric orchestration.
- Hyperscale Data Centers: Large-scale InfiniBand fabrics where external Subnet Managers provide unified control across hundreds of switches.
- Enterprise Cloud & Finance: Low-latency trading systems with centralized monitoring and policy management.
- Government & Education: National labs and university supercomputing centers that require dedicated fabric management appliances.
Fully interoperable with NVIDIA InfiniBand ecosystem: ConnectX-6/7 adapters, LinkX cables, and Quantum-2 series switches. Backwards compatible with HDR, EDR, and FDR devices. Requires an external Subnet Manager such as NVIDIA UFM (recommended for large fabrics), OpenSM, or other IB-compliant SM running on a dedicated server or VM. Supports major Linux distributions (RHEL, Ubuntu, Rocky Linux) and Windows Server with appropriate drivers.

For C2P airflow (connector-to-power), cold air enters from the OSFP connector side and exhausts through the power supply side. Verify your data center cooling layout before ordering. MQM9790-NS2R is the ideal unmanaged choice for racks requiring reverse airflow.
- Centralized Fabric Management: Perfect for deployments using NVIDIA UFM, enabling single-pane-of-glass management across hundreds of switches.
- Reverse Airflow Flexibility: C2P cooling matches specific data center hot/cold aisle configurations, improving thermal efficiency.
- Highest Radix in 1U: 64x 400G ports minimizes switch tiers, lowers latency, and simplifies cabling.
- Cost-Effective for Large Fabrics: Eliminates redundant onboard SM processors when external management is already deployed.
- Energy Efficient: Gold+ power supplies and smart fan control reduce OPEX.
- Future-Ready Scalability: Support for SHARPv3 and adaptive routing ensures investment protection for next-gen AI frameworks.
