Fibre Channel over Ethernet Protocol
Fundamental Elements of FCoE
This section identifies the basic features of and the premises upon which FCoE is being designed. FCoE specific objects & terminology are defined. Upon completion students are able to:
- Identify the basic features of FCoE.
- Draw a comparison between FCoE and other LAN-based SAN options.
- Identify the factors supporting the creation and promotion of FCoE technology.
- Describe the general concept of FC frame encapsulation.
- Identify key design challenges to FCoE.
Ethernet Review
This section reviews the basics of the Ethernet protocol with specific emphasis on this technology as the assigned physical & link layer for FCoE. Upon completion students are able to:
- Identify the stack which makes up the Ethernet MAC layer.
- Explain how 10G Ethernet is delivered.
- Identify how discovery and error recovery are performed by Ethernet.
- Identify the parts of the Ethernet header including the Vlan Qtag.
- Define lossless Ethernet.
- Describe the function of the Ethernet PAUSE feature.
- Compare and contrast PAUSE with the proposed Priority-based Flow Control.
Fibre Channel Review
This section reviews the fundamental concepts related to the FC-2, FC-3 and FC-4 layers of the Fibre Channel network stack. FC-specific objects and terminology are identified. Upon completion students are able to:
- Define the roles of the port types in FC.
- Describe the contents and format of a FC frame.
- Identify the steps involved in logging in with a FC switch.
- List the features of Class 3 FC.
- Describe how FC implements flow control.
- Define NPIV and explain how it affects the login process.
- Describe the concept of Exchange Management.
FCoE Architecture
This section discusses the architectural concepts & terminology associated to FCoE. Both features that have been agreed upon and proposed features will be discussed. Trace analysis is used to investigate the completion of SCSI IO through FC, through FCoE. Upon completion students are able to:
- Describe FCoE features & terminology
- Define the role of the FCoE Forwarder (FCF). Identify the port types associated to the FCF.
- Define the role of the ENode. Identify the port type associated to the ENode.
- Identify the encapsulation frame layout for FCoE frames.
FCoE Initialization Protocol (FIP)
This section details the FCoE Initialization Protocol (FIP) processes and frame format. Trace analysis is used to investigate both the FIP advertisement functions as well as discovery. Upon completion students are able to:
- Explain the need for FIP
- Explain the various proposed uses for FIP.
- Describe the process by which a Node would find a Switch using FIP.
- Describe the FIP's role in FLOGI.
- Describe the FIP's role with Extended Link Services.
