Numbers of Connections
The number of connections resulting from cabling one adapter into a switch or
hub depends on failover mode and how many links the configuration has:
■ If a controller pair is in transparent failover mode and the port 1 link is
separate from the 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), each adapter will
have one connection, as shown in Figure 12.
■ If a controller pair is in transparent failover mode and port 1 and port 2 are on
the same link (that is, all ports are on the same loop or fabric), each adapter
will have two connections, as shown in Figure 13.
■ If a controller pair is in multiple-bus failover mode, each adapter has two
connections, as shown in Figure 14.
