Quad-port 25 Gb/s OCP 3.0 adapter

The Broadcom BCM957504-N425G is a quad-port 25 Gb/s Ethernet network adapter built for OCP 3.0 server slots. It targets data-centre operators and cloud builders who need high-density 25/10 GbE connectivity for virtualization, storage disaggregation and high-performance computing workloads.

OCP 3.0 form factor with four SFP28 cages

The card uses the Open Compute Project 3.0 form factor and presents four SFP28 connectors for direct-attach copper or optical transceivers. NIC partitioning supports 16 physical functions, while the TruFlow engine accelerates vSwitch processing and the BroadSAFE silicon root of trust hardens platform security.

Verify OCP 3.0 slot and SFP28 optics compatibility

Confirm your server chassis accepts an OCP 3.0 mezzanine card and that the PCIe 4.0 x16 electrical interface is available. Ensure you have suitable 25 Gb/s or 10 Gb/s SFP28 modules and cables for the intended link distances, and that your operating system supports the advanced RoCE, SDN and NVMe-oF features.

Vragen over dit artikel

What throughput does the OCP 3.0 interface support on this adapter?

The OCP 3.0 interface on the BCM957504-N425G delivers line-rate, full-duplex throughput at 25 Gbps per port across its four SFP28 connectors.

What physical slot and form factor does this quad-port card require?

The BCM957504-N425G uses the OCP 3.0 form factor and installs in a PCI Express 4.0 x16 slot.

How is the adapter installed, and what step is commonly missed?

Insert the card into a PCIe 4.0 x16 slot, secure the OCP 3.0 latch, then connect SFP28 modules and cables; the step often missed is fully engaging the latch until it clicks.
