Non-redundant host and drive loops
The following illustration shows examples of configurations that have non-redundant
host and drive Fibre Channel. These configurations have a single path on the host
and drive Fibre Channel loop. If either path fails, the host is not able to access storage
until the path is repaired. The single controller (Model 3542-1RU) configurations have
a single Fibre Channel loop to the hard disk drives. These configurations have no
path failover protection.
