Description
BCM957504-N425G is a Broadcom NetXtreme II quad‑port Ethernet NIC for servers. It provides four 2.5 Gb/s Ethernet ports (2.5GBASE‑T, RJ‑45) on a PCIe adapter (PCIe Gen2 x4). Used to add high‑density network connectivity in servers/workstations. Typical features include NIC offloads (checksum offload, Large Send/Receive Offload), support for jumbo frames, VLAN tagging, and RSS for load distribution across CPUs. The N425G suffix indicates 4x2.5 GbE capability. For exact specs (drivers, OS support, virtualization features) consult Broadcom’s datasheet or the server vendor’s hardware compatibility guide.
Features
BCM957504-N425G is a 4-port 25GbE network adapter. Key features:
- 4x 25 GbE ports (SFP28) for high-density 25Gb Ethernet
- PCIe 3.0 host interface (x8)
- RoCEv2/RDMA capable for low-latency data transfers
- Offloads: TCP/IP offload, LSO/LRO, checksum offload
- RSS/multi-queue for scalable performance
- Jumbo frame support and advanced VLAN (802.1Q/802.1ad)
- Virtualization ready: SR-IOV, VMQ, NIC teaming
- Broadcom driver support for Windows, Linux, and VMware; management utilities via Broadcom tools
Note: exact feature set can vary by firmware/drivers; verify with the latest Broadcom spec sheet for your OS and hypervisor version.
