Hard Drive and Drive Tray Installation

♦
Capacity (MB / GB) –
Use drives with the same capacity. RAID arrays use a “least-
common-denominator” approach. The maximum capacity of each drive the array can
use is the maximum capacity of the smallest drive. Choose big drives of the same
size.
♦
Profile –
The drive trays and bays of the system are designed for 3.5” wide x 1” high
hard drives. It is highly recommended that users do not try to use drives of any other
size.
♦
Drive Type –
The ES subsystem described in this manual can ONLY use SCSI-320
hard drives. Please ensure that you purchase the correct hard drives.
2.10.2 Hard Drive Installation
The hard drive must first be installed into a drive tray before the tray is installed into the
ES chassis.
Step 1.
Place the SCSI-320 hard drive into the drive tray
(as shown in
Figure 2- 3
)
making sure that the hard drive is oriented in such a way that the single
connector attachment (SCA) connector is facing the back of the drive tray.

Step 2.
Adjust the drive’s location
until the mounting holes in the drive canister are
aligned with those on the hard drive. Secure the drive with 4 supplied 6/32
flat-head screws. (See
Figure 2- 3
)
WARNING:
Only use screws supplied with the drive canisters. Longer screws might damage the
drive.
2.10.3 Drive Tray Installation
Once the hard drives have been installed in the drive trays, the drive trays must be
installed into the ES subsystem.
