Channel Redundancy

You can create a virtual disk that uses physical disks that are attached to different controller channels. The physical disks may reside in an external enclosure or the backplane (internal enclosure). If the virtual disks maintain redundant data on different 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 different 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.
