HPE P51178-B21

4-Port Gigabit Ethernet Card

The HPE P51178-B21 is a high-performance **Broadcom BCM5719 Ethernet 1Gb 4-port Base-T Adapter** designed to enhance the network connectivity of HPE servers. This network interface Ethernet Card (NIC) provides four Gigabit Ethernet ports, offering a reliable and scalable solution for demanding network environments. It is an ideal component for a variety of applications, including virtualized environments, network-intensive applications, and data centers that require multiple, high-speed connections for improved redundancy and performance.

This adapter is engineered by HPE for seamless integration and optimal performance with HPE Gen10 Plus and Gen11 servers. It leverages a **PCI Express 2.0 x4** interface to deliver a maximum data transfer rate of 1 Gbit/s per port, ensuring efficient data flow. A key feature of this adapter is its advanced security, which includes **digitally-signed firmware** authentication to protect against malicious attacks and unauthorized firmware installation.

Features :

The **P51178-B21** is a feature-rich networking solution. It provides **four RJ-45 ports** that support 1000Base-T, 100Base-TX, and 10Base-T network technologies, offering broad compatibility. The Ethernet Card design helps to reduce CPU utilization by supporting various I/O offloads, including **Remote Direct Memory Access (RDMA)** and tunneling, which frees up server resources for other tasks. This makes it an excellent choice for bandwidth- and latency-sensitive applications. The adapter's plug-in Ethernet Card form factor makes it easy to install in a compatible HPE server's PCIe slot, and it is a low-power, energy-efficient component that helps to reduce overall operational costs.

Advanced Options :

For IT administrators and network architects, the **HPE P51178-B21** is a strategic component for building a robust and resilient network infrastructure. The inclusion of four ports on a single Ethernet Card allows for more efficient use of PCIe slots, which is particularly valuable in space-constrained server configurations. You can use the ports for link aggregation to increase bandwidth, or to provide network redundancy and failover for mission-critical applications. The advanced security features, such as the digitally-signed firmware, are essential for protecting against modern cyber threats. By deploying this adapter, businesses can ensure high-speed, secure, and reliable network connectivity, which is a foundational requirement for any modern data center or enterprise environment.
