Basic concepts

WWN
The world wide name (WWN) is a 64-bit address that identifies a fabric or an entity (such as an FC
switch, node, or port) in an FC SAN. The upper-layer protocol of FC uses WWNs for communication.
Each entity has a factory-assigned globally unique WWN.
FC address
The FC protocol accesses communication entities in an FC SAN through FC addresses. An FC address
is also known as an FC ID.
