Supermicro AOC-STGN-I2S Network Interface Card

The Supermicro AOC-STGN-I2S is a low-profile PCIe add‑on network card that delivers dual 10 GbE connectivity through two SFP+ ports. Built around the Intel 82599ES controller, it provides two independent 10 Gigabit Ethernet channels over SFP+ interfaces, making it ideal for upgrading servers, storage arrays, or virtualization hosts that demand high-throughput networking. The card uses a PCIe x8 interface and fits standard LP (low-profile) server slots, with overall dimensions of 4.0" (10.2 cm) in length and 2.73" (6.9 cm) in height (without brackets). Typical power draw is around 11.2 W. Each SFP+ port supports SFP+ transceivers or SFP+ direct-attach copper (DAC) twinax cables up to 10 meters, enabling short-range, high-bandwidth links within a data-center rack. This combination makes the AOC-STGN-I2S well suited for applications requiring reliable, scalable 10 GbE performance in compact server chassis.
