Failover Reference Configuration 11:
One host with two dual port SAS HBAs and one PowerVault^"* with one LT04 SAS and LT05
SAS drive
In this configuration, failover occurs if one of the drives in the library fails (hard\ware failure or drive is
disconnected from the HBA).
In the event a single port in the SAS drive fails, failover will take effect and data will be streamed onto
the same drive using the second SAS connection.
In the event a SAS drive fails; failover will result on control path and data moved to the additional drive
in the library
The physical connection of this configuration is shown in Figure 11
