Dual-domain SAS for Cascaded Dual-port JBOD 2000

This dual-domain SAS architecture provides redundant pathways for two cascaded dual-port
JBOD 2000 as in Figure 46. The "C PRI" ports on two JBOD 2000 are connected with one mini-
SAS cable, and the "C SEC" ports are connected with another mini-SAS cable (see the red lines
in Figure 46). One connector of the SAS controller is connected to "A PRI" port on one JBOD
2000, and the other connector of the controller is connected to "B SEC" on the other JBOD
2000. This connection mode provides redundancy pathways and eliminates any single point of
failure.
