Redundant Controller
12.1 Operation Theory
12.1.1 Physical Connection
Details in the topological configurations of redundant controllers can
be found in the Hardware Manual that came with your controller. The
proceeding discussions will focus on the theories and the
configuration process of a redundant controller system. Users who
are familiar with the practice of redundant controller configuration,
please jump to section "12.3 Configuration."
� SCSI Interface
Figure 12 - 1 Redundant Configuration Using SCSI
Controllers
The physical connection between controllers should be similar to
the one shown above. All channels should be connected to both
controllers. The path default for controller communications (SCSI)
is channel 0. Channel 0 is also the default for host interface;
therefore, avail other channel for host connection by changing its
channel mode.
