4.2 Host Connection Topology
4.2.1 Single Host
Figure 4-2: Single SCSI Controller Connected to a Single Host Computer
In the example shown in Figure 4-2, the SCSI ports are connected to two adapters on
a host computer to provide path redundancy. If one of the host channels becomes
disconnected, or if the cable connecting one of the host ports to the host computer is
damaged, data flow will be routed through the second path from the subsystem to the
host computer.
NOTE:
To create dual redundant data paths on the host side, you will need to install a
third-party fail-over software on the host computer.
