SAS2-936EL Series Backplane User's Guide
The SAS2-936EL2 backplane has two expanders which allow effective failover
and recovery.
3-2 Failover
Single Host Bus Adapter
In a single host bus configuration,
the backplane connects to one host
bus adapter.
Single Host Bus Adapter Failover
If the expander or data path in Port
A fails, the system will automatically
fail over to Port B.
