Dell / Nvidia ConnectX-6LX Dual-Port 25GbE SFP28 NIC

The Dell / NVIDIA ConnectX-6 Lx OCP 3.0 NIC (Dell P/N: 0DN78C) is a high-performance, enterprise-grade network adapter designed to deliver fast, reliable connectivity for modern data centre environments. Featuring a dual-port SFP28 configuration, this card supports up to 25GbE per port, providing a total potential throughput of 50Gb/s. Built on NVIDIA’s advanced ConnectX-6 Lx architecture, it offers exceptional bandwidth, ultra-low latency, and highly efficient packet processing, making it ideal for demanding workloads such as virtualisation, cloud computing, and high-speed storage networking.

Engineered for efficiency and scalability, this adapter includes a wide range of intelligent hardware offloads that reduce CPU overhead and improve overall system performance. Support for technologies such as RDMA over Converged Ethernet (RoCE v2), SR-IOV, and advanced packet acceleration ensures optimised performance in virtualised and software-defined environments. The dual SFP28 ports provide excellent flexibility, allowing compatibility with both 10GbE and 25GbE infrastructure using SFP+ and SFP28 transceivers or DAC cables, making it a cost-effective upgrade path for evolving network demands.

Designed in the OCP 3.0 form factor, this NIC is intended for installation in compatible Dell PowerEdge servers equipped with a dedicated OCP slot, rather than a standard PCIe slot. This bracketless design improves airflow and simplifies installation while maintaining a clean internal layout. Fully integrated with Dell firmware and management systems, the ConnectX-6 Lx ensures seamless operation, reliable performance, and enterprise-level security features, making it an excellent choice for data centres seeking high-speed, future-ready networking solutions.
