Network Card Broadcom NetXtreme N225P 2 x 25G OCP 3.0

The Broadcom NetXtreme N225P 2x25G OCP 3.0 is a high-performance server network adapter that provides two 25 Gbps internal fiber ports and a PCI Express host interface. Based on Broadcom's scalable 10/25/50/100/200G controller architecture, the N225P is intended for enterprise and cloud-scale networking and storage environments, including high-performance computing, telco, machine learning, storage disaggregation, and data analytics. The adapter combines a high-bandwidth Ethernet controller with integrated hardware acceleration engines to increase throughput and reduce CPU overhead.

Advantages

The NetXtreme N225P offers hardware-accelerated flow processing and tunneling protocol offloads (Geneve, VXLAN, NVGRE), which significantly increase throughput while lowering CPU utilization compared to software-only solutions. TruFlow technology raises virtual machine density, freeing CPU cycles for additional workloads. The adapter supports advanced data center features such as RoCE, SDN and NFV and is designed for scalable, feature-rich networking in modern server deployments.

Suitable for

• Data center server networking and storage connectivity
• High-performance computing clusters
• Telco infrastructure and cloud provider deployments
• Machine learning and data analytics workloads
• NVMe-oF and storage disaggregation solutions

How to use

Install the N225P adapter into a compatible OCP 3.0 server slot with a matching PCI Express connection following the server vendor's hardware installation procedures. Connect internal fiber links to the server backplane or compatible cabling for 25 Gbps lanes. Install the appropriate Broadcom drivers and firmware, then configure network settings and advanced offloads (tunneling, RoCE, TruFlow) through the operating system or management tools to achieve optimal performance for target workloads.

Recommendations

Use the NetXtreme N225P in servers that support OCP 3.0 form factors and ensure firmware and drivers are up to date. Enable hardware offloads and tunneling protocol processing when deploying virtualization, NVMe-oF, or large east-west traffic workloads to reduce CPU load and maximize throughput.
