Attention:
Possible loss of data access – You must install alternate path software or an alternate
path (failover) driver on the host to support failover in the event of an HBA failure or a host
channel failure. Simplex controller configurations do not support failover.
One host to a storage array
The following figure shows an example of a switch topology with one host, a controller shelf, and a
zoned switch. Each outlined group of ports on the switch represents a zone.

The following table lists the redundant and non-redundant components in a switched configuration
with one host and a controller shelf.

Use two switches for full redundancy. A single
zoned switch is not redundant.

Two hosts to a storage array
The following figure shows an example of a switch topology with two hosts, a controller shelf, and a
zoned switch. Each outlined group of ports on the switch represents a zone.
Note:
The hosts/servers in this example must be clustered to be redundant.
