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.
