Dell PowerVault™ TL4000/TL2000 Failover Guide

(one host, two HBAs, two switches, two FC drives)

Main Path

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
