Move more traffic through the server without reworking the rack. This AddOn PCIe Ethernet adapter delivers dual 10 GbE RJ-45 connectivity in a plug-in card form factor, giving infrastructure teams a direct path to higher bandwidth on copper infrastructure. The PCI Express 2.0 x8 host interface provides the lane width expected for serious server networking, while Intel X540 chipset support anchors the design in a proven controller family. For environments standardizing on RJ-45, this card avoids the cost and complexity of a fiber migration where copper still fits the architecture. Dual ports support redundancy, segmentation, or workload separation, and the server-focused design makes it a practical fit for virtualization hosts, application servers, and storage-adjacent systems that need predictable throughput. This is the kind of adapter chosen when the network path matters as much as the server itself. It is built for teams that need dependable 10 GbE performance, familiar cabling, and a card that slots cleanly into existing PCIe infrastructure.
