Redundant configuration with minimum cabling and paths to all
interface modules
Figure 15 on page 58 illustrates a redundant configuration with minimum cabling
and paths from each host LUN to all six interface modules. In this configuration:
v Each host is equipped with dual HBAs. Each HBA (or HBA port) is connected to
one of two Fibre Channel switches.
v Each Fibre Channel switch has a connection to three separate interface modules.
v Each volume has six paths.
