•The HSG60 and HSG80 documentation refers to the controllers as Controllers A (top) and B (bottom). Each controller provides two ports (left and right). (The HSG80 documentation refers to these ports as Port 1 and 2, respectively.) In transparent failover mode, only one left port and one right port are active at any given time.
With transparent failover enabled, assuming that the left port of the top controller and the right port of the bottom controller are active, if the top controller fails in such a way that it can no longer properly communicate with the switch, then its functions will automatically fail over to the bottom controller (and vice versa).
•In transparent failover mode, you can configure which controller presents each HSG60 or HSG80 storage element (unit) to the cluster. Ordinarily, the left port of either controller serves the units designated D0 through D99, and the right port serves those designated D100 through D199.
