Detailed Specifications
HPE P51178-B21 Broadcom BCM5719 4-Port 1GbE Adapter
Overview
The HPE P51178-B21 is a quad-port 1Gb Ethernet network adapter designed to enhance connectivity and performance in modern server infrastructures. Engineered specifically for HPE ProLiant Gen10 Plus and Gen11 servers, this adapter provides a reliable and scalable solution for environments requiring increased I/O bandwidth and network resiliency without compromising on server efficiency. It addresses the need for high-speed, low-latency connectivity in enterprise data centers, hybrid cloud services, and virtualized environments. This adapter leverages the Broadcom BCM5719 controller to deliver its full feature set. Key technologies include support for various I/O offloads, such as TCP Segmentation Offload (TSO) and Receive Side Scaling (RSS), which significantly reduce CPU utilization. By offloading network processing tasks from the server's main processor, it frees up valuable CPU cycles for critical applications, resulting in improved overall system performance and efficiency for network-intensive workloads. Physically, the P51178-B21 is a low-profile, plug-in card that installs into a PCIe 2.0 x4 slot. Its design ensures compatibility and seamless integration within supported HPE server platforms. Management is unified through existing HPE server tools, allowing for consistent configuration and monitoring. Security is a core component, with digitally signed firmware authenticated through a root-of-trust architecture to prevent unauthorized firmware and protect the server infrastructure.
