Table 3: Failover Configuration Requirements
Failover Support Configuration Details
This section details the configuration requirements that must be meet in order to support failover using
the Dell PowerVault™ TL2000 or TL4000 library.
Important Note: Failover support is limited to the Dell PowerVault™ TL4000 when configured with LT04
drives.
Configuration Samples
Please refer to the following diagrams for cabling the supported failover configurations. The drive
shown as the failover path does not need to be on standby (i.e. not in use) for failover to occur.
Failover Reference Configuration 1:
One host, one Fibre Channel switch and one Dell PowerVault^*^ library with two Fibre Channel
drives
In this configuration, failover occurs if one of the drives in the library fails (hardware failure or drive is
disconnected from the Fibre Channel switch). The physical connection of this configuration is shown in
Figure 1.
Important Note: The Fibre Channel Drive Generation can be LT04 or LT05
