HPE P51181-B21 Broadcom 1Gb 4-Port OCP3 Adapter
Overview
The HPE P51181-B21 is a Broadcom BCM5719 quad-port 1GbE network adapter designed for modern HPE ProLiant Gen10 Plus and Gen11 servers. This adapter provides a dedicated and efficient connectivity solution, leveraging the Open Compute Project (OCP) 3.0 form factor. It is engineered for environments that require reliable Gigabit Ethernet connectivity for backend server management, mixed workloads, or legacy network infrastructures, ensuring stable and consistent performance. This network adapter is built to optimize server networking performance by offloading specific tasks from the CPU. It supports advanced features such as TCP Segmentation Offload (TSO), Receive Side Scaling (RSS), and UEFI PXE Boot, which collectively help reduce processor utilization and improve overall system efficiency. These capabilities make it a cost-effective choice for enhancing network throughput without a significant power consumption increase. Designed for seamless integration, the P51181-B21 fits into the dedicated OCP 3.0 mezzanine slot in compatible HPE servers. This plug-in card design simplifies installation and helps maintain a clean, organized server interior with minimal cabling. Management is streamlined through HPE’s standard toolsets, allowing IT administrators to configure and monitor the adapter as an integral part of the server infrastructure, ensuring consistent and reliable network operations.
