There are, basically, three options for creating zones. They are:
WWN:
Advantage: You can plug the the fibre in to any switch, any port & it’ll work.
Disadvantage: If the HBA dies, you have to update the zone definition.
Port zone
Advantage: Probably the easiest setup - allows any port to any port comms
Disadvantage: Problems arise if either port dies or the cable gets accidentally relocated.
Nick names
Advantages: Same advantage as WWN zoning
Disadvantages: Same disadvantage with the addition of maintaining nick name lists.
