What You Get: 10Gtek 82576-2T-X1 1.25GbE PCI-E X1 Network Card (compare to Intel E1G42ET) x1, Low-profile Bracket x1. Backed by 10Gtek 30 Days Free-returned, 3 Year Free Warranty and Lifetime Technology Support. 10Gtek's 82576-GE-2T-X1 is a PCI Express x1 10/100/1000Mbps Dual RJ45 Port Ethernet adapter based on Intel 82576 chipset, compatible with PCIex4, x8, x16 lane. The adapter is mainly designed for Industrial Control, and the performance is optimized, so that the system I / O is no longer the bottleneck of high-end network applications .The adapter has integrated hardware acceleration to perform TCP / UDP / IP checksum offload and TCP segmentation tasks. Host processing technology can sub-load accelerator, release CPU resources occupied to free up more CPU resources to handle with other applications. The adapter is based on Intel 82576EB Gigabit Ethernet MAC PHY (Media access Controller and physical Interface Transceiver) dual port controller.
