概述

Description

BCM957504-N425G is a Broadcom NetXtreme PCIe Ethernet adapter. It’s a 4-port 25 GbE NIC for servers/data centers, exposed as four 25G Ethernet interfaces. The card plugs into a PCIe slot (typical x8) and uses standard 25G optics (SFP28 or DAC options, depending on SKU). It supports hardware offloads, jumbo frames, RSS/multi-queue, and virtualization features (e.g., SR-IOV) for high‑throughput workloads. Driver support is Broadcom’s bnxt_en/Linux and Windows drivers. Used for high‑bandwidth server connectivity, storage networks, and VM hosts. Verify exact form factor (full-height/low-profile) and the port optics in your SKU.

Features

Here are the typical features of Broadcom BCM957504-N425G (4-port 25GbE PCIe NIC):
- 4 x 25 GbE network ports (SFP28) for high-density 25Gb connections
- PCIe host interface (commonly PCIe Gen3 x16)
- Support for optical SFP28 or copper DAC cables
- Hardware offloads: TCP/IP offload, Large Send/Receive, checksum offloads
- High‑performance networking features: RSS (multi-queue), jumbo frames
- Virtualization and isolation: SR-IOV, VMQ, NIC teaming (bonding)
- QoS and traffic management: VLAN offload, LACP/link aggregation
- OS and hypervisor support: Windows, Linux, VMware ESXi, and other major platforms
- Manageability: Broadcom management tools and standard NIC management interfaces
- PXE boot support for network booting
Note: Exact capabilities (e.g., supported PCIe revision, optic types, and offload specifics) may vary by revision and firmware. Please consult the official datasheet for precise specifications.

Package

Low-profile PCIe NIC card (4-port Broadcom BCM957504-N425G) with a PCIe x4 interface.

Pinout

BCM957504-N425G is a Broadcom PCIe Ethernet NIC. It provides four Ethernet ports (the N425G variant indicates 4×25 GbE in many implementations) and is used as a PCIe add‑in card. The pin count depends on the package (PCIe card-edge vs. other package); please refer to the specific datasheet or package drawing for the exact pin count.
