Basic Active-Active Single-Port Topology
Choose this topology when your application requires a high-
performance, robust, full system-level fault-tolerant disk storage solution
with transparent controller failover/failback. This dual controller
configuration supports a host with a single-port HBA and is ideal when
the host driver software does not support LUNs that appear twice.
Note: This configuration is shown with hubs enabled.
Connect the fibre channel data cables as shown in
Figure
2-28.
