摘要: The entire FCoE fabric is a single virtual domain, even though there may be multiple FCFs and FDFs. The virtual domain is a different Domain_ID than any of the FCFs. In certain embodiments there are multiple FCFs, of which one is selected as the master or designated FCF. The master FCF performs normal fabric configuration in conjunction with the Fibre Channel fabric. The master FCF assigns the virtual domain FC node IDs and controls development of subdomain IDs. Virtual links are instantiated between the master FCF and other FCFs, between top level FDFs and the FCFs and between the FDFs at each of various levels. FDFs connected to ENodes proxy the master FCF for most FIP operations. FIP FLOGI and FDISC operations are handled by the master FDF, but the FDFs convert the FIP FLOGI requests to VD_FLOGI requests, which include information about the FDF handling the transaction.

摘要: A method of initializing a Fibre Channel over Ethernet (FCoE) link between a Fibre Channel over Ethernet node (ENode) and Fibre Channel Forwarders (FCFs) in a network by discovering the presence of FCFs available to the ENode and other FCFs, assigning second MAC addresses to the ENode corresponding to each available FCF, and converting from a management and initialization process using the first MAC address to normal Fibre Channel operation using the second MAC addresses. The implementations described herein may additionally distinguish management and initialization processes from normal Fibre Channel operation using separate Ethertypes.

摘要: A Fibre Channel over Ethernet (“FCoE”) frame format allows a Fibre Channel (“FC”) base frame to be transmitted and routed through an Ethernet network. In one implementation, an FCoE frame includes SCSI information represented in a FC frame to which is prepended an FCoE header. The FCoE header/FC frame combination is encapsulated in an Ethernet frame shell to form an FCoE frame. Implementations of the FCoE frame may include an FCoE header containing fields and data pertaining to the version of the FCoE header of the FCoE frame, synchronized time values, various flags, directional values, and type values.
