Channel Redundancy And Thermal Shutdown

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 may also be used for disks that reside in enclosures subject to thermal shutdown. If the enclosure attached to one of the channels turn off, redundant data is maintained on the other channel.

Channel redundancy is implemented by selecting physical disks on different channels when using the Create Virtual Disk Advanced Wizard.
