Chapter 3. Fibre Channel over Ethernet

Introduction

Fibre Channel over Ethernet (FCoE) is a standard that has been developed by the FC-BB-5 working group of INCITS Technical Committee T11 [13], [14], [15], [17]. FCoE is based on the observation that Fibre Channel is the dominant storage protocol in the Data Center and that any viable I/O consolidation solution for storage must be based on the Fibre Channel model.

The idea behind FCoE is extremely simple: implement I/O consolidation by carrying each Fibre Channel frame inside an Ethernet frame. SCSI is mapped over FC as in native Fibre Channel and each resulting FC frame is encapsulated in an Ethernet frame. The encapsulation is performed on a frame-by-frame basis; therefore, it ...
