Site-based allocation

In a Remote Mirror configuration (also known as a campus cluster or stretch cluster), the hosts and storage of a cluster are divided between two or more sites. These sites are typically connected through a redundant high-capacity network that provides access to storage and private link communication between the cluster nodes.

Configure the disk group in a Remote Mirror site to be site-consistent. When you create volumes in such a disk group, the volumes are mirrored across all sites by default.
