• For redundant controller with redundant JBODs
To ensure the system can continue its operation without any interruption
in the event of any SAS JBOD failure, a loop construction is suggested.
Figure 2-15 shows an example of the loop implementation with a
redundant RAID system and SAS JBODs. Users can create as below:
The connection shown in Figure 2-15 enables all the three JBOD chassis to
be looped through the redundant-controller system. In this way, the data
is transmitted from node to node around the loop. Once the JBOD2 is
failed and causes interruption, JBOD1 and JBOD3 still work normally via
the redundant path.
