FIBRE CHANNEL OVER ETHERNET

摘要

The use of Ethernet as an underlying transport for Fibre Channel (FC) frames is disclosed in the Fibre Channel Over Ethernet (FCOE) protocol. In FCOE, the FC physical layer and part of the FC-2 link layer are replaced with the Ethernet physical and link layers. Each FC frame is encapsulated within an Ethernet Frame. The payload of the FCOE frame contains type information from the FC Start Of Frame (SOF) indicator, the FC header, an optional FC payload, and type information from the FC End Of Frame (EOF) indicator. In one embodiment, an Ethernet network carrying FCOE replaces a standard FC network. In another embodiment, devices implementing FCOE may be implemented in a blade server. The entire backplane is Ethernet, over which both storage and networking traffic can be run. The Ethernet links are connected to an Ethernet switch, a FCOE/FC converter, and a FC switch.

1. An Ethernet device comprising:
a processor operable to generate an Ethernet frame comprising: a destination Media Access Control (MAC) address translated from a Fibre Channel (FC) destination address using an Address Resolution Protocol (ARP); a source MAC address translated from an FC source address using the ARP; an Ethertype value indicating that the Ethernet frame is a Fibre Channel over Ethernet (FCoE) frame; an FCoE Start Of Frame (SOF) translated from an FC SOF, the FCoE SOF being a first type; an FC header; and an FCoE End Of Frame (EOF) translated from an FC EOF, the FCoE EOF being a second type, wherein the first type and the second type are represented differently.
