Dual Host Bus Adapter
In a dual host bus configuration, the
backplane connects to two host bus
adapters.
Dual Host Bus Adapter
Failover
If the expander or data path in the
primary ports fails, the system auto-
matically switches to the secondary
ports. This maintains a full connection
to all drives.
