Dual-port 10Gbps SFP+ adapter

The Supermicro AOC-STGN-I2S is a PCI-Express network adapter that provides two SFP+ ports for 10Gbps Ethernet connectivity. It is built around the Intel 82599 controller and targets servers that need high-speed LAN or SAN links. The card suits administrators expanding bandwidth in rackmount or tower systems.

PCI-Express slot with two SFP+ cages

Installation requires one free PCI-Express slot and compatible SFP+ transceivers or direct-attach cables, which are not included. The dual-port design lets you aggregate links or separate traffic without consuming additional expansion slots. It frees up I/O capacity for storage or compute cards in dense chassis.

Controller-rated thermals and power

The Intel 82599 controller is engineered for continuous 10Gbps operation within standard server airflow. Typical power draw stays within the PCI-Express slot budget, so no auxiliary power connector is needed. Acoustic output depends on the host system fans rather than any onboard cooling.
