Hard Drive Installation
Hard Drive Installation Prerequisites
Hard drives for the Galaxy HDX4 have been pre-installed in the drive
canisters. However if a drive is defective, use this procedure to install
a drive into a drive canister. Before installing 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:
This model accommodates SAS or SATA-II (3Gbps)
hard drives.
MUX Board:
MUX boards are required if using SATA drives in a
redundant-controller configuration both in RAID and the expansion
enclosures.
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 possible impact during installation
