Broadcom M225P Internal Fiber 25000 Mbit/s PCI Express Wired

The Broadcom NetXtreme-E Series M225P is a dual-port 25GbE internal fiber PCIe OCP 2.0 adapter designed for servers in enterprise, telco and cloud-scale environments. Based on Broadcom’s scalable 10/25/50/100/200G Ethernet controller architecture, this adapter combines a high-bandwidth controller with on-chip hardware acceleration to deliver high throughput and efficient CPU offload for networking and storage workloads.

Advantages

The M225P 2x25G adapter provides hardware acceleration engines that improve network performance and server efficiency, supporting features such as TruFlow™ for increased VM density and on-chip tunneling protocol processing for Geneve, VXLAN and NVGRE. These capabilities yield significant throughput improvements and reduce CPU utilization compared with software-only solutions. The adapter supports advanced networking technologies including RoCE, SDN and NFV and is suited to modern data center requirements such as NVMe-oF and high-performance computing.

Suitable for

• Enterprise and cloud data center servers
• High-performance computing and machine learning clusters
• Telco infrastructure and virtualized network functions (NFV)
• Storage disaggregation and NVMe-oF deployments
• High-throughput server-to-server networking

How to use

Install the adapter into a compatible server OCP 2.0 PCIe slot following your server vendor’s installation instructions and safety procedures. Connect fiber interfaces to the network or switch supporting 25GbE links. Install Broadcom-provided drivers and firmware appropriate for your server operating system, then configure link settings, VLANs and tunneling/acceleration features (for example Geneve or VXLAN) via the host OS or management software to enable hardware offload functions.

Recommendations

Use certified 25GbE fiber transceivers and cables, keep firmware and drivers up to date, and verify compatibility with server vendor OCP 2.0 implementations. For best performance in virtualized environments, enable TruFlow and on-chip tunneling offload and test configuration under expected workloads to tune VM density and CPU offload settings.
