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.
