The Dell Broadcom 2-Port 25/10 Gb/s PCIe 3.0 x8 OCP 3.0 Network Adapter (0NHN45 / NHN45) is a high-performance server networking solution built on the Broadcom BCM57414 controller, delivering reliable, low-latency Ethernet connectivity for modern data center and cloud environments. This adapter is also identified by the Broadcom reference part number BCM957414N4140C, ensuring cross-platform compatibility and easy replacement sourcing.
Designed in the OCP 3.0 small-form-factor (SFF) mezzanine format, this NIC integrates seamlessly into supported Dell PowerEdge 14th and 15th generation servers, providing space-efficient, high-bandwidth networking for virtualization, software-defined networking, and storage workloads.
With dual SFP28 ports supporting 25GbE, 10GbE, and 1GbE speeds, the Dell NHN45 network adapter offers flexible connectivity options while the PCI Express 3.0 x8 interface ensures full line-rate performance. Advanced features such as RDMA over Converged Ethernet (RoCE v1/v2), SR-IOV, and NIC Partitioning (NPAR) reduce CPU overhead and improve overall system efficiency in highly virtualized environments.
