Broadcom BCM957412N4120C Dual-Port 10Gb/s PCIe Network Adapter for OCP Systems

Broadcom Dual-Port 10 Gb/s Ethernet PCI Express 3.0 x8 OCP 3.0 SFF Network Adapter

The Broadcom BCM957412N4120C is a high-performance dual-port 10 Gigabit Ethernet PCI Express 3.0 x8 adapter designed for Open Compute Project (OCP) 3.0 compliant systems. This compact, plug-in card features two SFP+ network connectors that support optical fiber modules and copper direct attach cables, providing versatile connectivity options for enterprise and data center environments. Built with Broadcom's BCM57412 25GbE MAC controller and an integrated dual-channel 10GbE SFI transceiver, this adapter ensures reliable and fast data transmission across your network infrastructure. It supports high bandwidth throughput up to 8000 MB/s, making it ideal for demanding applications such as virtualization, high-speed data transfer, and network virtualization. The adapter's compliance with the SFF-8402 standard ensures seamless integration within compatible hardware, and its advanced features like SR-IOV with up to 128 virtual functions, virtual network encapsulation (VXLAN, NVGRE, Geneve, GRE), and network offloads optimize performance and reduce CPU load. Additional capabilities include jumbo frames up to 9 KB, advanced congestion avoidance, and support for network boot via PXE or UEFI, making it suitable for booting servers over the network. The device also supports RDMA over Converged Ethernet (RoCE), DCB (Data Center Bridging), and multiple scaling features such as multiqueue, VMQ, and RSS, ensuring efficient and scalable network operation. Designed for server, client, or workstation environments requiring high-speed connectivity, this adapter is a reliable solution for expanding network bandwidth while maintaining compatibility with a broad range of networking standards and protocols. Its robust feature set and adherence to OCP specifications make the Broadcom BCM957412N4120C an excellent choice for data centers and enterprise networks seeking scalable, high-performance Ethernet connectivity.
