Types of MetroCluster configurations
The MetroCluster configuration is of two types—Stretch MetroCluster configuration and Fabric-attached MetroCluster configuration.
Stretch MetroCluster configurations provide data mirroring and the additional ability to initiate a failover if an entire site becomes lost or unavailable.
Like mirrored HA pairs, fabric-attached MetroCluster configurations contain two complete, separate copies of the data volumes or file systems that you configured as mirrored volumes or file systems in your HA pair. The fabric-attached MetroCluster nodes can be physically distant from each other, beyond the distance limit of a stretch MetroCluster configuration.
