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.
