Intra-site configuration
Chapter 8: Hardware Installation for Synchronous Mirroring
The intra-site configuration is the lowest-cost configuration of all three
configurations. It is used in environments where a long-distance fabric is not
required because of the close proximity of the hosts and storage arrays.
Because the intra-site configuration only has two switches, it is similar to

the campus configuration. However, multiple-switch fabrics do not exist in
this configuration.
The configuration is redundant for host bus adapters, controllers,

Synchronous Mirroring ports, and switches but is a single point of failure
for the site because all of the equipment can be destroyed by the same
disaster.
The highest availability campus configuration is the recommended

configuration, because it is fully redundant, which makes disaster recovery
easier.
