3.1.1.6 FC-4

FC-4 defines the interface mapping between the lower levels of the Fibre Channel and the various command

sets. These various command sets are known as upper layer protocols (ULPs). Examples of upper layer proto-

cols include SCSI, IPI, HIPPI, and IP.

3.1.2 Relationship between the levels

FC-0, FC-1, and FC-2 are integrated into the FC-PH document. The other documents are separate so that

each implementation may use the technology best suited to the environment in which it will be used.

3.1.3 Topology standards

Each topology has its own standard. This is done so that designers can concentrate on documents that apply

to the technology suited to their specific area of interest.

The following topology standards are available:

• FC-FG (Fibre Channel Fabric Generic)

• FC-SW (Fibre Channel Cross-point switch)

• FC-AL (Fibre Channel Arbitrated Loop)

The FC-FG and FC-AL documents are of the most interest for Seagate disc drive interconnection.

3.1.4 FC Implementation Guide (FC-IG)

FC-IG provides some implementation guidance for all Fibre Channel systems.
