Fabric-attached MetroCluster configuration on single-enclosure HA pairs

You can configure a fabric-attached MetroCluster configuration between a pair of single-enclosure HA pair systems. In this configuration, the HA pair between the two controllers in each chassis is deactivated, and two separate, side-by-side MetroCluster configurations are formed between the four controllers.

When the system detects the presence of an FC-VI adapter, which connects the controller to the switch fabric, the internal InfiniBand connection is automatically deactivated.

The following figure shows a fabric-attached MetroCluster configuration on single-enclosure HA pair systems:
