Cabling the ISLs in a MetroCluster configuration with array LUNs
Suggest changes
PDFs
You must connect the FC switches across the sites through Inter-Switch Links (ISLs) to form switch fabrics in your MetroCluster configuration with array LUNs.
-
Connect the switches at each site to the ISL or ISLs, using the cabling in the table that corresponds to your configuration and switch model.
The switch port numbers that you can use for the FC ISLs are as follows:

* The Cisco 9250i switch uses the FCIP ports for the ISL. There are certain limitations and procedures for using the FCIP ports.
Ports 40 through 48 are 10 GbE ports and are not used in the MetroCluster configuration.
