Dell PowerVault™ TL4000/TL2000 Failover Guide

Failover configuration

(one host, one switch, two FC drives)

Main Path

Failover Path

Figure 10: Reference Configuration 10

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 (hardware 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
