Question #10

In order to avoid poor SAN design, you should do all of the following except:

a. Use world wide name zoning for flexibility and port zoning for security.
b. Use a maximum of 16 switches per fabric.
c. Minimize hops and the use of ISL links.
d. Use multiple HBA vendors and drivers, if possible.

The correct answer is:
d. Use multiple HBA vendors and drivers, if possible.

The best way to configure your SAN is to standardize on a single HBA vendor and drivers whenever possible. This is because drivers can be the main culprit for you SAN failing to work properly. Standardizing on HBA vendors and drivers helps to ensure compatibility and keeps your SAN running.
