Chapter 3. FCoE Storage Connectivity

FCoE (Fibre Channel over Ethernet)

Fibre Channel over Ethernet (FCoE, pronounced “ef-see-oh-ee”), is an encapsulation of FC frames over Ethernet networks. The spec is governed by the T11 Technical Committee, which is part of the InterNational Committee for Information Technology Standards (INCITS). FCoE is defined in T11 FC-BB-5 standard (Fibre Channel BackBone—5), available at www.t11.org/ftp/t11/pub/fc/bb-5/09-056v5.pdf. (Later revisions might exist by the time you read this book.)

FCoE maps FC directly over Ethernet but is independent of the Ethernet forwarding scheme. The spec replaces Layers 0 and 1 of the FC stack (see Chapter 2, “Fibre Channel Storage Connectivity”), which are the physical and the ...
