If you're adding more Ethernet ports to a server or upgrading your setup for better performance, this 4-port 1Gb card from HPE gets the job done without taking up much space or power. It connects through a PCIe 2.0 x4 slot and supports full gigabit speed on all four ports, giving you up to 8 Gb of total throughput. It's a solid pick for tasks like virtualization, network segmentation, or handling lots of traffic without slowing down. It also supports features like jumbo frames, VLAN tagging, and large send offload, which help keep things running smoothly, especially in busy environments.
