HPE 1Gb 4-Port 331T PCIe 2.0 x4 Ethernet Adapter

The HPE 647594-B21 is a 4-port 1Gb Ethernet adapter designed to expand or upgrade your server’s network capabilities efficiently. It fits into a PCIe 2.0 x4 slot and delivers full gigabit speed on each of its four ports, providing up to 8 Gb of total throughput. This makes it a reliable choice for environments that require stable, high-speed connections, such as virtualization setups, network segmentation, or handling heavy network traffic without bottlenecks.

Built with a Broadcom BCM5719 chipset, the adapter supports advanced features like jumbo frames, VLAN tagging, and large send offload. These features help optimize network performance and reduce CPU load, especially in busy or complex network environments. The card’s low power consumption and single-chip design make it an energy-efficient option that won’t add unnecessary heat or power draw to your system.

Installation is straightforward thanks to the included full-height and low-profile brackets, allowing the adapter to fit into a wide range of server cases. It is compatible with 10/100/1000 Mbps networks and operates reliably within a temperature range of 32 to 131 degrees Fahrenheit. Whether you’re upgrading an existing server or building a new one, this adapter offers a practical and effective way to increase your network port count and improve overall connectivity.
