Fabric Switch Zoning
Background Information
If an array or multiple arrays and multiple computers are attached to a fibre channel switch, by default the switch acts as a hub, relaying information from all ports to all other ports.
A number of problems are created, however. If a computer has two ports, both ports being connected to the switch, and a single channel array is connected to the switch, the computer sees the array twice. In most cases, if this occurs, the computer is confused and does not for- mat the array properly. With a
Fabric Switch Zoning Techniques
As Fibre channel switches advanced, they became managed. They used switch manage- ment software to control the settings
There are three techniques for zoning:
•Plain and Simple (has a tendency to be “trafficky”)
•Host Grouped
•1:1 Relational
Example 1
Here is a basic example, with a
By default, without zoning, the computer sees two copies of the array on each of the two channels. Each channel of the array sees two copies of the computer. The switch also con- stantly tests the remaining six ports to see if anything is attached. To fix this problem, the switch needs to be zoned, per the following 1:1 Relational
Create two zones:
•Zone 1 contains ports 1 and 2
•Zone 2 contains ports 3 and 4
