Dual-domain SAS

Using dual-ported drives and dual controllers, or a controller capable of supporting dual domains,

provides dual-path redundancy from the server. Figure 2 shows an example of a single controller

capable of dual-domain support. The dual-domain SAS configuration in Figure 2 can tolerate

simultaneous single port failure in a dual-port, dual-domain capable controller, external cable failure,

and expander failure.
