Setting up Redundant Path Support on the PERC 6/E Adapter

The PERC 6/E adapter can detect and use redundant paths to drives contained in enclosures. With redundant paths to the same port of a device, if one path fails, another path can be used to communicate between the controller and the device. For more information about redundant paths, see Redundant Path With Load Balancing Support.

To set up a configuration with redundant paths, both ports on a controller must be cabled to the IN ports of a single enclosure.

To add multiple enclosures, both OUT ports of the first enclosure must be cabled to the IN ports of the next enclosure.

If the connection between an OUT port on the controller and an IN port on an enclosure fails, an alternate path exists through the second OUT port on the controller and the second In port on the enclosure. For more information, see Figure 4-11, Figure 4-12 and Figure 4-13.

NOTE: The PERC 6/E adapter supports redundant paths when used with Dell PowerVault MD1000 and Dell PowerVault MD1120 disk storage enclosures.

Figure 4-11 displays Redundant path Storage Configuration with one enclosure.

Figure 4-11. Redundant Path Support Configuration With One Enclosure

Figure 4-12 displays Redundant path Storage Configuration with two enclosures.

Figure 4-12. Redundant Path Support Configuration With Two Enclosures

Figure 4-13 displays Redundant path Storage Configuration with three enclosures

Figure 4-13. Redundant Path Support Configuration With Three Enclosures

A single PERC 6/E adapter can support up to three disk storage enclosures in a redundant path configuration.

NOTE: Ensure that the latest firmware version is installed on your storage controller. You can download the latest firmware from the Dell Support website at support.dell.com and flash it to the firmware on the controller. For the latest firmware installation instructions, see the system documentation located on the Dell Support website at support.dell.com.

Perform the following steps to configure the hardware to utilize redundantpaths on the PERC 6/E adapter:

  1. Set up an enclosure on the PERC 6/E adapter.

  2. Connect two SAS cables from the OUT ports on your PERC 6/E adapter to the IN ports of the external enclosure. See Figure 4-3 to view the connection of the cables from the external enclosure to the PERC 6/E adapter.

NOTE: For information on Unified Mode, see the enclosure documentation that was shipped with the system.
  1. To add multiple enclosures, cable both OUT ports of the first enclosure to both IN ports of the next enclosure.

After you set up the hardware, the controller detects the redundant paths and automatically utilizes them to balance the I/O load.
