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.

NOTE: For PCIe-SSD, connectors are referred to as PCIe-SSD extenders.

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.

NOTE: Channel redundancy only applies to controllers that have more than one channel and that

attach to an external disk enclosure.

Creating A Channel-Redundant Virtual Disk

NOTE: Channel redundancy only applies to controllers that have more than one channel and that

attach to an external disk enclosure.

The following instructions provide information on creating a virtual disk that uses channel redundancy.

1. Launch the Create Virtual Disk Advanced Wizard:

a) In the Server Administrator window, under the system tree, click Storage dashboard.

b) Locate the controller on which you are creating a channel-redundant virtual disk and expand the

controller object until the Virtual Disks object is displayed.

c) Select Virtual Disks and click Go To The Create Virtual Disk Wizard.

d) Click Virtual Disk Advanced Wizard.

2. Follow the steps in Create Virtual Disk Advanced Wizard.
