2.8. Hard Drive Installation
2.8.1 Hard Drive Installation Prerequisites
Hard drives for the Uniwide subsystem must be purchased separately. When
purchasing the 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. It is highly recommended that you do not try
to use drives of any other size.
Drive type: The AR3016G described in this manual can use SATA-II or
SATA-I hard drives. Please ensure that you purchase the correct hard drives.
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 lift
and the possible impact during installation may damage your drives.
1. Handle hard drives with extreme care. Hard drives are very
delicate. Dropping a drive onto a hard surface (even from a short
distance) and hitting or touching the circuits on the drives with your
tools may cause damage to the drives.
2. Observe all ESD prevention methods when installing drives.
3. Only use screws supplied with the drive canisters. Longer screws
may damage the drive.
