SAN question
 
I have found myself between two design alternatives and am wondering which is the safer/ technically correct path to take. I need a SAN starting with 75 host ports which must be expandable to a maximum of 200 host ports. I am wondering whether to use one large director switch (FOr example one with 256 ports) or go for a Core/Edge design which might incorporate many many switches and provide the necessary ports. Is there anything essentially wrong with using a standalone director switch for a large SAN? Is there any technical advantage to either method?

I would say, out my experience, that having one director is a better solution. As simple as it may sound, its just easier having one director in one spot than many switches. Diagnosing any problems that arrive are also easier with one director.

I agree. One director makes it easier to troubleshoot, however provides no redundancy. If you need redundancy, go with two directors for the fabric.
