Quad Port Copper Gigabit Ethernet PCI Express Server Adapter Intel® i350AM4 Based

Silicom’s Quad Port Copper Gigabit Ethernet PCI Express Server adapter is PCI-Express X4 Copper Gigabit Ethernet network interface card that is based on a single chip, non-Bridged quad port GBE controller.

Silicom’s Quad Port Copper Gigabit Ethernet PCI Express Server adapter is the ideal solution for implementing multiple network segments, mission-critical high-powered networking applications and environments within high performance servers.


Silicom’s Quad Port Copper Gigabit Ethernet server adapter is based on Intel i350 Quad port Gigabit Ethernet MAC+PHY of Intel Controller.

The Silicom i350 support PCI-SIG Single-Root I/O virtualization and sharing specification (SR-IOV).
