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
supportedenclosuresareDell™PowerVault™MD1000andPowerVaultMD1120.ThisfeatureenablesloadbalancingbyfasterprocessingofI/Orequests.
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, more than one enclosure can be connected to a controller in a redundant path mode. You can connect up to three PowerVault
MD1000 and MD1120 to a PERC 6/E controller in a daisy-chained enclosure. And, you can connect up to four PowerVault MD1200 and MD1220 to a PERC H800
controller in a daisy-chained enclosure. See the figure below for an example of a daisy chain configuration (for PERC 6/E controller.)
If the communication channel between the connector and the first enclosure is lost, the redundant path configuration itself is lost. In this case, the health of
the logical connector is displayed as critical. Navigate to the Information/Configuration subtab of the logical connector to view details of the "Path Health."
See the table below for a brief outline of this scenario.
However, if the communication channel between any two enclosures is lost, the redundant path configuration is degraded and the health of the logical
connector is displayed as degraded. See the table below for a brief outline of this scenario.
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.
