Zoning with EMC Machines
The following are 3 options for creating zones for EMC Symmetrix and Clariion Machines.
1. WWN (WorldWide Name):
a. Advantage: You can plug the the fibre in to any switch, any port & it’ll work.
b. Disadvantage: If the HBA dies, you have to update the zone definition.
2. Port zone
a. Advantage: Probably the easiest setup – allows any port to any port communication.
b. Disadvantage: Problems arise if either port dies or the cable gets accidentally relocated.
3. Nick Names
a. Advantages: Same advantage as WWN zoning
b. Disadvantages: Same disadvantage with the addition of maintaining nick name lists.
