Switch zoning for the intra-site configuration
The intra-site configuration provides switch redundancy, but the switches are not cascaded and are
independent of each other.
The switches do not need to be zoned exactly as presented in this configuration. However,
Note:
you must meet the following requirements when zoning switches for the intra-site configuration.
You must have a total of four zones on each controller in this configuration.
You must 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.
You must zone the switches so that a single host adapter can only access one controller per storage
array.
The switches in the following figure contain 16 ports each, which leaves many unused ports per
switch. The remaining ports can be distributed among the other zones. However, make sure that most
of the remaining ports are assigned to the zones that contain the host connections: zone 1 and zone 2.
This assignment allows for easy setup for connecting additional hosts.
For simplicity, in this example, the switches use one-half of the ports for each zone, although zone 3
and zone 4 require fewer ports.
