Disk Shelf Front and Back Panel Components

Disk Shelf Front Panel Components - Oracle disk shelves are high-availability serial attached
SCSI (SAS) devices that provide expanded storage. The main components are hot-swappable,
including drives, I/O Modules (IOMs) or SAS Interface Module (SIM) boards for connecting
to controllers and other disk shelves, and dual load-sharing power supplies with integrated fan
modules. This provides a fault-tolerant environment with no single point of failure. Component
status is indicated with lights on the disk shelf, and in the Maintenance > Hardware screen of
the BUI.
Note -
