Your question is not clear, which server you want to configure ? What do you mean with ISL ?

Well an ISL may be enough but you may want to use more than a single port and Trunk them to avoid bottlnecks, also remember to add the Trunk / ISL to all zones that will be replicated (or create a DR zone). Also depending on distances you may need high power SFPs.
