HPE® 394791-B21 alternative Intel 82576 NIC PCIe 2.0 x4 Dual Port 1GbE RJ45

The PCIe* v2.0 (2.5GT/s) Intel 82576 GbE Network adapter is a single, compact, low power component that offers two fully integrated Gigabit Ethernet Media Access Control (MAC) and physical layer (PHY) ports. 

The 82576 enables two-port implementation in a relatively small area and can be used for server system configurations such as rack mounted or pedestal servers, where it can be used as add-on NIC or LAN on Motherboard (LOM) designs. 

Another system configuration is blade servers, where it can be used as LOM. The 82576 can also be used in embedded applications such as switch add-on cards and network appliances.
