Redundant Path Configuration
Does my controller support this feature? See "Supported Features."
This feature is supported only on SAS controllers with firmware version 6.1 or later., which can be connected to enclosures (and not backplanes). The
supportedenclosuresareDell™PowerVault™MD1000andPowerVaultMD1120.ThisfeatureenablesloadbalancingbyfasterprocessingofI/Orequests.
In a redundant path configuration, connect both the connectors of a SAS enclosure—which must be in a unified mode—to both connectors of a controller.
Storage Management detects this configuration and displays it on the user interface as a redundant path configuration. The two connectors (Connector 0 and
Connector 1) that were previously available are now replaced with one Logical Connector.
In a daisy chain scenario where more than one enclosure is connected to a controller in a redundant path mode, Storage Management allows you to connect a
maximum of three enclosures in a daisy chain. See the figure below for an example of a daisy chain configuration.
NOTE: This feature requires that the physical devices connected to the controller have the latest firmware. For the latest supported firmware, see the
Dell Support website at support.dell.com.
