Broadcom BCM957414A4142CC 25 Gbps dual-port SFP28 network card

Dual-port 25 Gbps SFP28 NIC for enterprise servers

This Broadcom BCM957414A4142CC card delivers two 25/10 Gbps SFP28 ports over a PCIe 3.0 x8 interface. It targets cloud-scale and enterprise servers that need line-rate, full-duplex throughput for virtualization, storage disaggregation, and high-performance computing workloads. Hardware features include NIC partitioning with 16 physical functions, a TruFlow engine for vSwitch acceleration, and BroadSAFE silicon root of trust for platform security.

PCIe 3.0 x8 bandwidth and SFP28 transceiver limits

The card operates at PCIe 3.0 x8 speeds, so the host slot must provide at least eight lanes of third-generation bandwidth to sustain dual-port 25 Gbps line rate. Each SFP28 cage accepts 25G or 10G transceivers and corresponding direct-attach or optical cables; 100 Gbps or 200 Gbps modules are not supported on these ports. Congestion-avoidance logic and RoCE support run entirely on the controller, but total throughput cannot exceed the electrical limits of the x8 link or the SFP28 interface.

Verify slot width, transceiver type.

Confirm the server motherboard has a free PCIe 3.0 x8 or wider slot with adequate bracket clearance for a low-profile or full-height bracket as supplied. Select SFP28 optics or DACs rated for 25 Gbps or 10 Gbps that match your link distance and fiber type. Ensure the target operating system or hypervisor includes a driver for the Broadcom P225P controller family to enable NIC partitioning, TruFlow, and congestion-management features.
