Installing Hard Drives
Hard drives are purchased separately. When purchasing hard drives, please consider
the following factors:
2.8.1
Prerequisites
Capacity (MB/GB): Use hard drives that have the same capacity and rotation speeds.
RAID arrays use a “least-common-denominator” approach meaning the maximum
capacity used in each drive for comprising a logical configuration is the maximum
capacity of the smallest drive. Profile: The enclosure drive bays are designed for
3.5-inch wide x 1-inch pitch hard drives.
Drive Interface Type: The enclosure accommodates SATA-II (3Gbps) or SATA-III
(6Gbps) hard drives.
NOTE
The hard drives and drive trays should only be installed into the system after it has
been mounted into a rack cabinet. If the hard drives are installed first, the system will
be too heavy to handle and the possible impact during installation may damage your
hard drives.
