Failover Reference Configuration 3:
One host with dual port SAS HBAs and one Dell PowerVault^"* with two SAS drives
In this configuration, failover occurs if one of the following occurs:
- One of the drives fails (hardware failure or is drive disconnected from the HBA port)
- One of the HBA ports fails
- One of the ports in a drive fails
This configuration takes full advantage of path failover; it is protected via data and control path.
The physical connection of this configuration is shown in Figure 3.
Important Note: Dell Recommends Fibre Channel drives to be same generation. For Heterogonous
configurations refer to section: Heterogonous Validated Configurations
