In a MetroCluster configuration with array LUNs, you must connect the storage array ports that form a redundant port pair to alternate FC switches.
The following illustration shows the connections between storage arrays and FC switches in a two-node fabric-attached MetroCluster configuration with array LUNs:
The connections between storage array ports and FC switch ports are similar for both stretch and fabric-attached variants of two-node MetroCluster configurations with array LUNs.
If you plan to use disks in addition to array LUNs in your MetroCluster configuration, you must use the switch ports specified for the configuration with disks. |
In the illustration, the redundant array port pairs for both the sites are as follows:
-
Storage array at Site A:
-
Ports 1A and 2A
-
Ports 1B and 2B
-
-
Storage array at Site B:
-
Ports 1A' and 2A'
-
Ports 1B' and 2B'
-
FC_switch_A_1 at Site A and FC_switch_B_1 at Site B are connected to form fabric_1. Similarly, FC_switch_A_2 at Site A and FC_switch_B_2 are connected to form fabric_2.
The following table lists the connections between the storage array ports and the FC switches for the example MetroCluster illustration:
