The figure shows a representative multiple-bus failover configuration. Restricting the
access of unit D101 to host BLUE can be done by enabling only the connections to host
BLUE. At least two connections must be enabled for multiple-bus failover to work. For
most operating systems, it is desirable to have all connections to the host enabled. The
example system, shown in Figure 6–2, contains three non-clustered Windows
NT/Windows 2000 hosts. Port 1 link is separate from port 2 link (that is, ports 1 of both
controllers are on one loop or fabric, and port 2 of both controllers are on another)
therefore, each adapter has two connections.
