We want to redesign our SAN topology and looking to what others are doing in the industry.

Currently we have a Cisco SAN core-edge topology. We will be buying all new switches and migrate to them. We will most likely be going with Brocade switches for our new SAN.

Is core edge still the best practice or are more people going with a new seperate switch for 2 cabinets and ISL into the core?

Is there a document on this? Can someone provide me with it.

Thanks!
