Broadcom BCM957414N4140C Dual-Port Network Adapter

Dual-Port 25GbE Networking for OCP Server Platforms

The Broadcom BCM957414N4140C is a dual-port 25 Gb/s Ethernet network adapter designed to the Open Compute Project OCP 3.0 Design Specification in a small-form-factor configuration. It provides two SFP28 network connectors and supports both SFP28 optical modules and copper direct-attach cables.

The adapter is built around the Broadcom BCM57414 25GbE MAC controller and connects to the host through an x8 PCI Express 3.0 interface. Hardware acceleration features include SR-IOV, RDMA over Converged Ethernet, TruFlow flow processing, vSwitch acceleration, and tunnel-aware offloads for VXLAN, NVGRE, Geneve, and GRE traffic.

Key Benefits and Features

• High-Speed 25GbE Performance: Dual SFP28 ports supporting 25 Gb/s Ethernet connectivity
• OCP 3.0 Integration: PCI Express 3.0 x8 host interface compliant with OCP 3.0 SFF specifications
• Advanced Virtualization: SR-IOV support with up to 128 Virtual Functions
• Low-Latency Offloads: RoCE support for converged Ethernet and RDMA workloads
• Hardware Flow Acceleration: Offloads for VXLAN, NVGRE, Geneve, GRE, IPv4, IPv6, TCP, and UDP processing

Ideal Use Cases

• OCP 3.0 server platforms
• Data center and cloud computing infrastructure
• Virtualized server environments
• Converged Ethernet and RDMA networking
