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.
NOTE 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 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, it is recommended that most of the remaining ports be 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.
Figure 14 Switch Zoning for the Intra-Site Configuration
Before proceeding, review the requirements in this section and the zoning example in
the figures to make sure that both switches are correctly zoned. For more information,
see "Switch Zoning Overview" on page 190.
