Single-port 50 Gbps QSFP28 NIC

The Broadcom BCM957414A4140C is a single-port network interface card that delivers 50 Gbps over a QSFP28 connector. It plugs into a PCI Express 3.0 x8 slot and supports 50, 25 and 10 Gbps line-rate, full-duplex throughput. The card targets servers that need high-density 50GbE connectivity in a single-slot form factor.

Sustained load behaviour with TruFlow

Under sustained traffic the TruFlow engine processes flows intelligently to increase server VM density and accelerate vSwitch processing. NIC partitioning provides 16 physical functions and SR-IOV supports up to 128 virtual functions for multi-tenant workloads. End-to-end congestion avoidance anticipates and eliminates congestion before it affects throughput. BroadSAFE silicon root of trust secures the platform during continuous operation.

Compatibility checks before ordering

Verify that the host system has an available PCI Express 3.0 x8 slot with sufficient bandwidth for 50 Gbps line rate. Confirm the chassis can accommodate a single-slot card and that a 50GbE QSFP28 transceiver or direct-attach cable matching the link distance is available. Ensure the operating system and hypervisor support SR-IOV, VXLAN, NVGRE and Geneve encapsulation for full feature use.

Questions about this item

How much power does the BCM957414A4140C draw when running at 50 Gbps all day?

The card is a PCIe 3.0 x8 device with a single QSFP28 port; total power depends on the transceiver or direct-attach cable fitted, which is not included.

What must I already own to make the BCM957414A4140C operational?

You need a free PCIe 3.0 x8 slot and a compatible 50GbE QSFP28 transceiver or copper direct-attach cable for the single port.

Will the BCM957414A4140C negotiate 25 Gbps or 10 Gbps links with my older switches?

Yes, the NIC supports standards-compliant 50/25/10G operation on the same QSFP28 port for backward compatibility.
