1.2 Drive Enclosures
This section explains the main components in the drive enclosure.
The drive enclosure contains drives installed in the front, and I/O modules and power supply units in the rear.
Up to 24 drives can be installed in a 2.5" type drive enclosure. Up to 12 drives can be installed in a 3.5" type
drive enclosure.
Since the power supply units are redundant, operations can continue even if one of them fails.
When a drive enclosure is connected, a DE-ID (drive enclosure number) is automatically allocated.
