Failover Reference Configuration 2:

One Host with one dual port Fibre Channel HBA, two Fibre Channel switches and one Dell

PowerVault^*^ with two Fibre Channel drives

In this configuration, failover occurs if one of the following occurs:

- One of the drives in the library fails (hardware failure or drive is disconnected from the Fibre

Channel switch)

- One of the switches fails

- One of the HBA ports fails

The physical connection of this configuration is shown in Figure 2.

Important Note: Dell Recommends Fibre Channel drives to be same generation. For Heterogonous
