Enclosure Bay Numbering and Drive ID
Allocation
The front panel of the F16F enclosure houses sixteen (16) hard drives in a
4x4 configuration as shown in
Figure 2-2
. When viewed from the front,
drive bays (slots) are numbered
0
to
15
from the left to the right, and then
from the top to the bottom.

IMPORTANT!
The drive numbering sequence is important when identifying a failed drive.
Removing the wrong drive can fatally fail a RAID array (RAID3/5).
Failing two members destroys a RAID6 array.

Hard Drive Installation
2.8.1 Hard Drive Installation Prerequisites
Hard drives for the subsystem must be purchased separately. When
purchasing hard drives, the following factors should be considered:
Capacity (MB/GB):
Use drives with the same capacity. RAID arrays use a
“least-common-denominator” approach. The maximum capacity of each
drive used in the array is the maximum capacity of the smallest drive.
Choose big drives with the same storage capacity.
Profile:
The drive trays and bays of the system are designed for 3.5-inch
wide x 1-inch high hard drives.
Drive type:
The subsystem is compatible with Fibre Channel interface
(4Gb/s or 2Gb/s) hard drives. Please ensure that you purchase the correct
hard drives.
CAUTION!
The hard drives and drive trays should only be installed into the subsystem
after the subsystem has been mounted into a rack cabinet. If the hard drives
are installed first, the subsystem will be too heavy to handle and the
