This chapter describes the Enterprise hardware components.
Fibre Channel drive enclosures
Thedriveencl
osure contains the disk drives used for data storage. A storage system includes multiple
drive enclos
ures. The major components of the enclosure are:
• 2.125-Gb, dual loop, 14-drive enclosure.
• Dual-loo p, FC-AL I/O modules and cable components that are the interface between the drives
and the host
controllers.
• Fiber o ptic cables.
• Copper Fibre Channel cables.
• Fibre Chann
el disk drives and drive blanks.
• Power and cooling components including power supplies, cords, and blowers.
• EMU that monitors the operation of the enclosure and the elements while displaying status. When
the EMU det
ects a condition, it generates a loc al alarm and reports the condition to the controller.
Enclosure layout
The disk drives mount in bays in the front of the enclosure (Figure 20). The bays are numbered sequentially
from left to right . A drive is referr ed to by its bay number. Enclosure status indicators are located in the
lower-right, front corner (see Figure 5). Figure 20 shows the front and rear views of the FC drive enclosure.
