Overview: Intel® FCoE/DCB User Guide
FCoE Infrastructure - Installation and Configuration
Intel® FCoE (Fibre Channel Over Ethernet) is designed for 82599- and X540-based PCI-Express Server Adapters. This guide
covers hardware and software installation, setup procedures, and troubleshooting tips for installing and booting the system
using these adapters.
Fibre Channel over Ethernet (FCoE) is defined as the encapsulation of standard Fibre Channel (FC) protocol frames as data
within standard Ethernet frames. This link level encapsulation, teamed with an FCoE-aware Ethernet-to-FC gateway, acts to
extend an FC fabric to include Ethernet based host connectivity. The FCoE specification focuses on encapsulation of FC frames
specific to storage class traffic, as defined by the Fibre Channel FC-4 FCP specification. FC is a market leading technology used
to create Storage Area Networks (SANs).
is a collection of standards-based extensions to classical Ethernet. It provides a lossless data
center transport layer that enables the convergence of LANs and SANs onto a single unified fabric. In addition to supporting
Fibre Channel Over Ethernet (FCoE) and iSCSI over DCB, it enhances the operation of other business-critical traffic.
FCoE VN to VN Support
The terms used in this section are defined below.
N_Port
A device port that generates/terminates FC-4 channel traffic
ENode (FCoE Node)
A Fibre Channel node (FC-FS-3) that is able to transmit FCoE frames using one or more
ENode MACs
FCoE_LEP (FCoE Link End-
Point)
The data forwarding component of an FCoE Entity that handles FC frame
encapsulation/decapsulation and transmission/reception of encapsulated frames through a
single Virtual Link
Lossless Ethernet network
An Ethernet network composed only of full-duplex links, Lossless Ethernet MACs, and
Lossless Ethernet bridging elements
Virtual Link
The logical link connecting two FCoE_LEPs
VN_Port (Virtual N_Port)
An instance of the FC-2V sublevel of Fibre Channel that operates as an N_Port (see FC-FS-3)
and is dynamically instantiated on successful completion of a FIP FLOGI or FIP NPIV FDISC
Exchange
VN_Port MAC address
The MAC address used by an ENode for a particular VN_Port
