Redundant Path Support (For PERC H810 Only)

The PERC H810 adapter can detect and use redundant paths to disks contained in enclosures. This provides the ability to connect two SAS cables between a controller and an enclosure for path redundancy. The controller is able to tolerate the failure of a cable or Enclosure Management

Module (EMM) by utilizing the remaining path.

When redundant paths exist, the controller automatically balances I/O load through both paths to each disk. Load balancing increases throughput to virtual disks in storage enclosures and is automatically turned on when redundant paths are detected. The ability to load balance I/O can be disabled using the Dell OpenManage storage management application.

To set up your hardware to support redundant paths, see "Setting up Redundant Path Support on the PERC H810 Adapter" on page 40.

NOTE: This support for redundant paths refers to path-redundancy only and not to controller-redundancy.
