In a stretch MetroCluster configuration with array LUNs, you must cable the FC-VI ports for direct connectivity between the controllers. In addition, you must cable each controller HBA port to switch ports on the corresponding FC switches. Cabling to the array LUNs is the same as that in a fabric-attached MetroCluster, except for E-Series array LUNs, which can be directly connected.
The following illustration shows the FC-VI ports cabled across controllers A and B in a stretch MetroCluster configuration:

FAS9000 storage systems controller modules use four FC-VI ports each. |
For configurations with E-Series array LUNs, you can directly attach the E-Series LUNs.
Except for connecting the FC-VI ports, the rest of this procedure is for setting up a MetroCluster configuration with array LUNs, that are not using E-Series array LUNs. This requires FC switches that are the same as using array LUNs in fabric-attached configurations.
