Setting Up Your Storage Subsystem

Basic Active-Passive Dual-Port Topology

Choose this topology when your application requires a high-
availability, high-access, fault-tolerant disk storage solution. This
dual controller configuration supports multiple hosts and failover
and failback operations. All LUNs are available to all hosts. The
dual host configuration is ideal for shared storage clustering.

Connect the fibre channel data cables as shown in
