Campus configuration

The campus configuration offers the same functionality as the highest availability campus
configuration, but the campus configuration contains only one switch at each site, rather than two.
The configuration is still redundant for host bus adapters, controllers, and remote mirroring ports, but
the configuration has a single point of failure for switches. If a switch at either site fails, the
Synchronous Mirroring feature or the Asynchronous Mirroring feature cannot operate. For this
reason, the highest availability campus configuration is highly recommended for total environment
redundancy.
The following figure shows a complete campus configuration. The controller-drive trays are shown
schematically with four host ports on each of two controllers in each controller-drive tray.
