Supermicro AOC-CTGS-I2T-O Dual-Port 10GBASE-T PCI Express 2.1 x8 Network Interface Card (Low Profile)

The Supermicro AOC-CTGS-I2T-O is a high-performance dual-port 10 Gigabit Ethernet network interface card designed for enterprise data centers and demanding network environments. Based on the Intel X540 controller, it delivers reliable 10 Gbps connectivity over standard RJ45 copper cabling, supporting both CAT6a and CAT6 cables. Its low-profile form factor with included full-height bracket ensures compatibility with a wide range of server chassis.

Advantages

This adapter provides exceptional throughput for virtualization, storage, and high-bandwidth applications. With support for jumbo frames up to 15.5 KB, iSCSI remote boot, FCoE, and advanced offload technologies, it reduces CPU overhead and improves network efficiency. Energy Efficient Ethernet (EEE) helps lower power consumption during low data activity.
