Intel® 82599 10 Gigabit Ethernet Controller: Datasheet



This document describes the external architecture (including device operation, pin descriptions, register definitions, etc.) for the 82599, a dual 10 Gigabit Ethernet (GbE) Network Interface Controller. This document is intended as a reference for logical design group, architecture validation, firmware development, software device driver developers, board designers, test engineers, or anyone else who may need specific technical or programming information about the 82599.


The 82599 is a derivative of previous generations of Intel 1 GbE and 10 GbE Network Interface Card (NIC) designs. Many features of its predecessors remain intact; however, some have been removed or modified as well as new features introduced.

Two versions are available:
• 82599EB - PCI Express* (PCIe*) 2.0, dual port 10 Gigabit Ethernet controller
• 82599ES - Serial 10 GbE backplane interface for blade implementations (includes the 82599EB SKU functionality plus serial)
