Port Zoning verses ISL?

[wsimps01]

Greetings All,
I'm relatively new to Storage and here is my question:
We are implementing a DR site that is about 50 miles away including our loops. I want to know if I can Fabric Zone our Brocade 2005_B32 switches (Silkworm 4100) from port to port or do I need to setup an ISL?
Any documents, links or inputs would be greatly appreciated.
We will be using our own fiber and our goal is disk to disk replication.
Thanks in advance for the help.

For the devices on either end to see each other will require an ISL.
Its easy if you have same switches at both sites, just set domain id to non-default number on one of the switches, then you can zone devices on either end and do all management via 1 switch.

If they are different, need to enable interop mode, change domain id etc.

linking two switches will establish an ISL automatically ... if the prereq's are fulfilled
