BCM957414N4140C

Overview

The Broadcom BCM957414N4140C is a dual-port 25 Gb/s Ethernet network adapter card designed to the Open Compute Project (OCP) 3.0 Design Specification in small form factor. It features two SFP28 network connectors and utilizes the Broadcom BCM57414 25GbE MAC controller with an integrated dual-channel 25GbE SFI transceiver. The card connects via an x8 PCI Express 3.0 interface compliant with the PCIe Base Specification Revision 3.0. Power consumption ranges from 9.1 Watts typical to 9.9 Watts worst-case at dual-port 25G operation, supplied by 12V and 3.3V edge connector pins. The package weighs 91 grams.

Feature Summary

• Dual-port pluggable media interface compatible with 25G SFP28 optical transceivers or copper direct-attach cables.
• SR-IOV support enabling up to 128 virtual functions for virtualized environments.
• TruFlow flow processing engine supporting VXLAN, NVGRE, Geneve, and GRE encapsulation/decapsulation.
• Advanced offload capabilities including TCP segmentation offload, receive-side scaling, and VLAN insertion/removal.

Applications

• Dual-port 25-Gigabit Ethernet adapter for OCP systems
• High-performance server networking
• Data center infrastructure

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm compliance with RoHS3 specifications and check for relevant environmental certifications such as REACH status. Ensure that the physical dimensions align with the OCP 3.0 Small Form Factor standard before integration into the target system chassis.

Selection Notes

Select this adapter for systems requiring high-density 25GbE connectivity within OCP 3.0 compliant chassis. Ensure the host platform provides adequate airflow, specifically 100 LFM at 55°C ambient temperature, to maintain junction temperatures below the maximum limit of 110°C. Verify compatibility with the required faceplate type, noting that the pull tab bracket is installed by default.
