Mellanox (NVIDIA) MQM9790-NS2F InfiniBand Switch | Product Launch & Key Features
May 28, 2026
As AI workloads, high-performance computing (HPC), and large-scale data centers continue to push bandwidth and latency requirements to new extremes, the networking backbone must evolve accordingly. Enter the Mellanox (NVIDIA) MQM9790-NS2F — a new-generation InfiniBand switch designed to break through traditional fabric bottlenecks. This 64-port OSFP platform delivers 400Gb/s per port, setting a fresh benchmark for scalable, low-latency, and lossless interconnects.
Why the MQM9790-NS2F InfiniBand Switch?
Conventional Ethernet solutions often struggle with tail latency and congestion when handling distributed AI training or massive parallel computing tasks. The MQM9790-NS2F InfiniBand switch solves these issues natively through NVIDIA’s SHARPv3 in-network computing and adaptive routing. For network architects and IT managers, this means predictable performance, even under the most demanding east-west traffic patterns found in GPU clusters.
Key Technical Highlights
The NVIDIA Mellanox MQM9790-NS2F is built on the latest NDR (Next Data Rate) InfiniBand architecture. It provides 64 OSFP ports, each capable of 400Gb/s, enabling an aggregated switching throughput of up to 51.2 Tb/s. Below is a quick reference to its core specifications:
| Feature | Specification |
|---|---|
| Model | Mellanox (NVIDIA) MQM9790-NS2F |
| Ports & Speed | 64x OSFP, 400Gb/s NDR per port |
| Switching Capacity | 51.2 Tb/s |
| In-Network Computing | SHARPv3, Adaptive Routing, Congestion Control |
When planning high-density deployments, engineers frequently look for MQM9790-NS2F datasheet and MQM9790-NS2F specifications to validate compatibility and power budgets. The switch supports advanced telemetry and out-of-band management, making it an ideal building block for GPU-driven data centers. For those evaluating procurement options, MQM9790-NS2F price and MQM9790-NS2F for sale inquiries are already rising across major channel partners.
Application Scenarios & Ecosystem Compatibility
As a flagship MQM9790-NS2F InfiniBand switch solution, this device natively integrates with NVIDIA Quantum-2 platforms. It remains fully MQM9790-NS2F compatible with existing HDR and EDR InfiniBand infrastructures, protecting previous investments while offering a clear upgrade path to 400Gb/s NDR. Whether building a new AI supercomputing cluster or scaling out a high-frequency trading fabric, the MQM9790-NS2F 400Gb/s NDR 64-port OSFP configuration delivers the density and low latency required for next-generation workloads.
