RAID Configuration Update
Host-based RAID configuration is supported using Dell PowerEdge RAID
Controller (PERC) 5/E and PERC 6/E.
Supported Hardware Configurations Using a
PERC 6/E Adapter
PERC 6/E adapters can detect and use redundant paths to drives in a Dell
PowerVault MD1000 enclosure. With redundant paths, if one path fails,
another path can be used to communicate between the controller and the
hard drive.
NOTE:
Redundant path connectivity is not supported on PERC 5/E adapters.
