About This Add-On Card
The Supermicro® AOC-STGS-i1T/i2T is the most feature-rich, low power 10Gbase-T controller
in the market today. Based on the Intel® X550 AT/AT2* chipset with features such as VXLAN
and NVGRE, this add-on card offers exible connectivity for all networking requirements. The
second generation integrated 10GbE MAC+PHY drives down both cost and power, enabling
a highly cost effective deployment of 10GbE in the data center. With Supermicro Asset
management and thermal detection to provide an extra layer of security and a peace of mind,
the AOC-STGS-i1T/i2T is among the most innovative 10GbE controllers in the market It is an
excellent choice to expand network connectivity in data centers and enterprise environments.
*The X550 AT is for the AOC-STGS-i1T, and the X550 AT2 is for AOC-STGS-i2T.
