1) FC Basics

Basics of what makes up a SAN

Basics of Fibre Channel protocol

2) What is a SAN

Technology that uses FC

FC open standard (IEEE T11 committee)

emulate channels larg block transfer behaviour while extending distance and allowing many to many connectivity

1,2,4,8,10,16 and 32 Gbit/sec

Fabric

Well-designed NETWORK of highly intelligent FC switches which provides enterprise-class scalability, performance, manageability and availability

Switches

Good LANs doesn´t make a good SAN´s

Fabric is a term used to describe a generic switching environment consisting of one or more interconnected switches (domains)
FID is used to identify each fabric int the SAN
FID can be from 1 to 128 and must be the same on each switch within the fabric

Each switch int the fabric has a domain ID (DID) configured

DID is used do identify each swich within the fabric

DID values can be 1 to 239 and must be different on each switch within the fabric

Port ID (PID); used to identify each node in the fabric

Assigned to the node by the domain it is attached to

Area ID The port index number the node is attached to

Node ID a number assigned to identify each node attached to the port
