Switch zoning for highest availability campus configuration
The highest availability campus configuration provides a separate zone for each reserved port for the
Synchronous Mirroring feature or the Asynchronous Mirroring feature.
The switches do not need to be zoned exactly as presented in this configuration. However, you must
meet the following requirements when zoning switches for the highest availability campus
configuration.
There are a total of four zones in this configuration.
• Zone 1 and zone 3 are on fabric 1 (switch 1A at the primary site, and switch 1B at the secondary
site).
• Zone 2 and zone 4 are on fabric 2 (switch 2A at the primary site, and switch 2B at the secondary
site).
Configure the zones on the switch so that there is one port per zone for a storage array connection
and one port per zone for each host. Switches are zoned so that a single host bus adapter port can
access only one controller per storage array.
Switches are zoned so that a single host bus adapter port can access only one controller for each
storage array.
Do not zone the uplink ports (E_ports) on any of the Fibre Channel switches.
Note:
The following figure shows how the four switches are zoned for the highest availability campus
configuration.
The switches have 16 ports each, which leaves unused ports on each switch when following the
preceding requirements. The remaining ports can be distributed among the other zones. It is
recommended, however, that most of the remaining ports be assigned to the zones containing the host
connections: zone 1 and zone 2. This port assignment allows easy setup for additional hosts to
connect to the environment.

Before you proceed, review the requirements listed in this section and the zoning shown in the figure
to make sure that all four switches are correctly zoned. For more information, see the
