Basic Stand-Alone Dual-Port Topology – DuraStor 7320SS Only
Choose a stand-alone dual-port topology when your application requires
a low-cost, entry-level, fault-tolerant disk storage solution. This solution
provides a single controller configuration that supports dual-ported
access with the internal hubs disabled. It is ideal in a host direct-attached
application or SAN environments when connected to an external switch
or hub. See
SAN Solution Strategies (DuraStor 7320SS only)

Other stand-alone dual port topologies are described in
