900-9X766-003N-ST0 Nvidia ConnectX-7 200GBPS NDR200 IB Single-Port OSFP PCIe 5.0 x16 Card Network Adapter

NVIDIA ConnectX-7 200Gb/s NDR200 OSFP Single-Port Adapters

The NVIDIA ConnectX-7 family represents the next step in high-performance data center networking, combining industry-leading throughput, ultra-low latency, and a deep set of hardware offloads and acceleration features tailored for modern HPC, AI, and cloud infrastructures. The specific SKU 900-9X766-003N-ST0 is a single-port OSFP adapter configured for 200Gb/s NDR200 InfiniBand (default) and 200GbE operation, implemented on a PCIe x16 host interface with Gen4/Gen5 SERDES support. This adapter is built for dense server platforms, RDMA workloads, and environments that demand both scalability and deterministic network behaviour. :contentReference[oaicite:0]{index=0}

High-Performance Computing (HPC)

ConnectX-7 adapters deliver deterministic latency, high message rate, and efficient RDMA primitives that accelerate MPI and collective communication patterns used in large supercomputers and cluster environments. The NDR200 transport reduces congestion and improves scaling for distributed compute jobs.

Distributed Machine Learning & AI Training

For multi-GPU training and parameter synchronization across nodes, the ConnectX-7’s high bandwidth and RDMA features minimize CPU overhead and deliver faster gradient exchange. Offloads for collective operations and in-network computing primitives can shorten iteration times and improve overall throughput on large models.

Cloud & Hyperscale Services

Cloud service providers benefit from the combination of high throughput, network virtualization features (SR-IOV, NVGRE/ VXLAN offloads), and robust security features in the ConnectX-7 family — delivering multi-tenant isolation without sacrificing performance.

Detailed specification breakdown

Below is a technical specification summary tailored to administrators, procurement teams, and systems architects evaluating the 900-9X766-003N-ST0 SKU and its subcategory peers.

Compatibility and ecosystem

The ConnectX-7 series is supported across major server vendors and operating systems. OEM variations of the same SKU (900-9X766-003N-ST0) appear in validated lists from Dell, Lenovo, and other system integrators. Firmware, drivers, and management tools are available from NVIDIA’s Networking documentation portal, and firmware release notes include important details about feature enablement and security options.

Optics & cabling considerations

OSFP ports require compatible OSFP optics (or vendor-supported breakout or transceiver options). When planning network topology, consider.

Firmware options

Security controls typically available in this product category include Secure Boot enablement and crypto feature toggles. Some SKUs (including variations of the 900-9X766 series) ship with Secure Boot enabled and cryptographic acceleration disabled or limited by default — consult the product ordering information and vendor datasheet for the exact configuration. Firmware updates often include security fixes, so have a robust update process and signing verification in place.

ConnectX-7 vs prior generations

Compared to ConnectX-6 and earlier families, ConnectX-7 adds higher line rates (NDR/400Gb options in some SKUs), expanded in-network computing, and additional accelerators for modern cloud and AI workloads. Choosing ConnectX-7 future-proofs infrastructure for next-generation RDMA and in-network acceleration capabilities.

Procurement guidance and SKU notes

The part number 900-9X766-003N-ST0 is one of several ConnectX-7 single-port OSFP SKUs offered by NVIDIA and its channel partners. When procuring.

Testing and performance validation examples

Industry best practices for validating a ConnectX-7 deployment include conducting both microbenchmark and macro benchmark tests:

Maintenance, firmware lifecycle,

Keep firmware and driver stacks under version control and follow NVIDIA’s published release notes and advisories for ConnectX-7. Firmware releases may add security hardening, bug fixes, and new protocol support; test updates in a staging environment before production rollouts. Reach out to NVIDIA or your OEM for enterprise support options and validated platform lists.

Card require special heatsinks or backplates

Some OSFP variants require an RHS cage or vendor-specific cooling solutions; check the mechanical compatibility guide and ensure server chassis airflow is sufficient for the chosen adapter and optics.

Driver and firmware packages should I use

Use the official NVIDIA (Mellanox) ConnectX-7 driver and firmware bundles published on NVIDIA’s networking documentation portal. Always match firmware to driver recommendations and test in a staging environment.

Technical for catalog editors 

When placing this content into a continuous category description, ensure that H2/H3 headings are preserved, technical bullet lists are kept concise, and that SKU-specific attributes (bracket height, secure boot, crypto options) are flagged for dynamic templating. Keep product datasheet links accessible for procurement teams, and include schema markup for product SKUs, specifications, and review snippets where applicable to improve SERP visibility.
