HPE P26269-B21 – Broadcom BCM57504 4-Port 10/25GbE OCP 3.0 Network Adapter

Overview

The HPE P26269-B21 is a high-performance OCP 3.0 network adapter based on the Broadcom BCM57504 controller, designed for HPE ProLiant Gen10 Plus and Gen11 servers. It provides four 10/25GbE SFP28 ports for high-bandwidth server networking in enterprise environments.

It is used to deliver low-latency, high-throughput connectivity for virtualization, cloud infrastructure, and storage networking workloads. The adapter supports modern Ethernet standards including 10GbE and 25GbE speeds over fiber or DAC connections.

This card is installed in OCP 3.0 slots, enabling efficient internal server networking without consuming standard PCIe expansion slots. It is optimized for dense data center architectures where port density and scalability are critical.

It integrates with Broadcom networking features such as virtualization offloads, RDMA support, and advanced packet processing for enterprise-grade performance.

Typical Deployment Scenarios

Used in HPE ProLiant rack servers for high-speed data center networking. Common in virtualization clusters, cloud computing nodes, storage networking (iSCSI/RoCE), and AI/compute workloads requiring high bandwidth and low latency. Also deployed in enterprise environments requiring scalable 25GbE connectivity.
