Intra-Site
Configuration
The intra-site configuration is used in environments where a long-distance fabric is
not required because of the close proximity of the hosts and storage arrays. The
configuration is still redundant for host bus adapters, controllers, remote mirroring
ports, and switches, but the configuration is a single point of failure for the site
because all of the equipment can be destroyed by the same disaster. For this reason,
the highest availability campus configuration is highly recommended for total
environment redundancy.
The following figure shows a complete installation of the intra-site configuration.
NOTE A switch failure in this configuration does not affect data access; however, as
a result, an Unsynchronized state might occur for all of the mirror relationships on both
the primary storage arrays and the secondary storage arrays.
