About sites and remote mirrors

In a Remote Mirror configuration (also known as a campus cluster or stretch

cluster) the hosts and storage of a cluster that would usually be located in one

place, are instead divided between two or more sites. These sites are typically

connected via a redundant high-capacity network that provides access to storage

and private link communication between the cluster nodes.

Figure 14-1 shows a typical two-site remote mirror configuration.
