while the backplane and its physical disks are internal.

Backplanes
You can view the Backplane object by expanding the controller in the Storage Management tree view. Storage Management displays the
status of the backplane and the attached physical disks. Backplane is similar to an enclosure. In a Backplane, the controller connector and
physical disks are attached to the enclosure, but it does not have the management features (temperature probes, alarms, and so on)
associated with external enclosures.
Enclosures
Storage Management enables management of various enclosures and their components. In addition to managing the physical disks
contained in the enclosure, you can monitor the status of the fans, power supply, and temperature probes in an enclosure. You can view
these components by expanding the controller, connector, and enclosure objects in the Storage Management tree view.
Storage management allows hot plugging of enclosures. Hot plugging is dened as the adding of a component to a system while the
operating system is still running.
NOTE
: This feature requires that the physical devices connected to the controller have the latest rmware. For the latest
supported rmware, contact your service provider.
After you hot plug or hot recongure an enclosure, refresh the left tree to display the change in status and conguration; a system reboot is
not required.
NOTE
: Storage Management does not allow hot removal of enclosures. Reboot the system to eect this change in Storage
Management.
