Good article.

Here's a basic question:

How does one verify which physical array the database files and backups are located on in a SAN? I suspect that I have my backups located on the same physical array as the data files and want to separate them. My network admin seems to think this does not matter anyway because according to her, there is only one controller for all the arrays. I always thought there are separate controllers for each array (no single point of failure!). We do not have an in-house SAN admin and I only have a basic understanding of how SANs work.

Thanks!
