Supermicro AOC-STGS-I2T-O Dual-Port 10 GbE Add-On Card

Supermicro AOC-STGS-I2T-O is a high-performance add-on network card designed for modern server environments requiring 10 Gigabit Ethernet over standard RJ-45 copper (10 Gbase-T). Built around the Intel X550 AT2 chipset, it offers dual RJ-45 ports and supports PCI Express 3.0 x4 (8 GT/s) to deliver efficient, low-latency connectivity.

Key advanced features include support for VXLAN and NVGRE tunneling, SR-IOV for virtualization, jumbo frames up to 15.5 KB, IEEE 1588 time synchronisation, and integration with Supermicro’s asset-management and thermal-detection capabilities.

Designed for data-centres, virtualised server infrastructures and high-throughput storage networks, this card is ideal for upgrading legacy 1GbE systems or adding high-speed connectivity without moving to fibre.
