Chapter 8: Hardware Installation for Synchronous Mirroring 193
Intra-site configuration 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.
