Connectors

A controller contains one or more connectors (channels or ports) to which you can attach disks. You can externally access a connector by

attaching an enclosure (for external disks) to the system or internally access by attaching to the backplane (for internal disks) of a system.

You can view the connectors on the controller by expanding the controller object in the tree view.

Channel Redundancy

You can create a virtual disk that uses physical disks that are attached to dierent controller channels. The physical disks may reside in an

external enclosure or the backplane (internal enclosure). If the virtual disks maintain redundant data on dierent channels, then these

virtual disks are channel redundant. Channel redundancy is when one of the channels fail, the data is not lost as redundant data resides on

another channel.

Channel redundancy is implemented by selecting physical disks on dierent channels when using the Create Virtual Disk Advanced

Wizard.

NOTE

: Channel redundancy only applies to controllers that have more than one channel and that attach to an external disk

enclosure.

Connector Health

The connector health page displays the status of the connector and the components attached to the connector.
