The top RAID Storage Array is the primary one (Fig. 7). The bottom RAID Storage Array
(Fig. 8) is the secondary (redundant) which is idle during normal operation and takes over
the management role when the Primary Controller cannot function properly due to hard-
ware error, controller module removal, etc.
The following picture is a suggestion for connecting two StoneFly RAID Storage Arrays to
a StoneFly USO-HA™ cluster. Figure 9 illustrates the RAID storage array expansion con-
nection.
