How local HA data protection works in a MetroCluster configuration

You need to understand how HA pairs work in the MetroCluster configuration.

The two clusters in the peered network provide bidirectional disaster recovery, where each cluster can be the source and backup of the other cluster. Each cluster includes two nodes, which are configured as an HA pair. In the case of a failure or required maintenance within a single node's configuration, storage failover can transfer that node's operations to its local HA partner.

The following illustration shows a MetroCluster FC configuration. The HA functionality is the same in MetroCluster IP configurations, except that the HA interconnect is provided by the cluster switches.
