PCI-E Network Card Broadcom NetXtreme P425G Quad-Port 25Gb SFP28 PCIe 4.0 x16

Broadcom NetXtreme P425G – Quad-Port 25GbE SFP28 Network Card

An enterprise network adapter from Broadcom's NetXtreme E-Series, with four 25 Gigabit ports over SFP28 and a PCIe 4.0 x16 interface. This card is built for servers, data centers and virtualization environments that demand high bandwidth, reliability and low CPU overhead.

Connectivity and Performance

The card is powered by the Broadcom BCM57504 controller and provides four 25GbE ports (also compatible with 10GbE), supporting SFP28/SFP+ optical modules and copper direct-attach (DAC) cables. The PCIe 4.0 x16 interface ensures there is no bottleneck even when all four ports run at full line rate.

Advanced Enterprise Features

The card supports RoCE (RDMA over Converged Ethernet) for low-latency data transfer, as well as SR-IOV with up to 1,000 virtual functions (VFs) for efficient resource allocation across many virtual machines. Support for SDN and NFV makes it ideal for modern software-defined networks.

Efficiency and Power

A typical power draw of just around 15.2 watts, combined with hardware offload engines that relieve the CPU, ensures efficient, cool operation even under sustained heavy network load.
