Intel E1G42ETG1P20 dual-port Gigabit network card

Dual-Port Gigabit Server Adapter

This Intel E1G42ETG1P20 adapter provides two RJ45 Gigabit Ethernet connections over a single PCI-Express slot. It is designed for servers and workstations that need additional wired network ports for segmentation or redundancy. The card targets IT administrators expanding connectivity in rackmount or tower systems without occupying multiple expansion slots.

PCI-Express Interface with Intel 82576 Controller

The card connects through a standard PCI-Express interface and is built around the Intel 82576 Gigabit Ethernet Controller. This controller handles all physical-layer and MAC functions for both ports. Compatibility depends on the host system providing an available PCI-Express slot and driver support for the 82576 chipset in the chosen operating system.

Sustained Multi-Core and Virtualisation Optimisation

The 82576 controller is engineered to scale across multi-core processors, distributing interrupt and packet processing load across available CPU cores. It includes hardware features that optimise throughput in virtualised environments where multiple guest systems share the physical adapters. Under continuous traffic the dual-port design maintains line-rate 1000 Mbps performance on each port simultaneously.
