Main Path

Failover Path

Figure 2: Reference Configuration 2

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
