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.
