Example network cabling topologies with Active-Passive
Two simple network cabling topologies using Active-Passive in high availability environments are
shown in Figure 26 (page 56).

The two-switch scenario in is a basic, yet effective, method for ensuring high availability. If either
switch fails, or a cable or NIC on one of the storage systems fails, the Active-Passive bond causes
the secondary connection to become active and take over.
