Dell PowerVault™ TL4000/TL2000 Failover Guide

Multiple Host Failover configuration

(two hosts, two FC switches, and 2 FC drives)

Main Path

Failover Path

Figure 5: Reference Configuration 5

Note that a SAN environment is susceptible to backup performance issues due to the sharing of

resources across multiple hosts. A failover event in the system can potentially complicate the

performance issues. Failover is a means to maintain the data storage flow in the event of a failure along

the communication path between the host and the drive or library, but the environment manager must

monitor the state of the system to ensure all the paths are active.

Failover Reference Configuration 6:

One host with dual port SAS HBA and one Dell PowerVault™ with a single SAS drive

In this configuration, failover occurs only if one of the HBAs fails. This configuration only supports data

path failover as there is no second drive to failover the control path. The physical connection of this

configuration is shown in Figure 6.
