Installing Hard Drives
Installation of hard drives should only occur after the enclosure has been
rack-mounted!
Hard Drive Installation Prerequisites
Hard drives are separately purchased and 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, meaning the maximum capacity used in
each drive for composing a RAID array is the maximum capacity of the smallest drive.
Therefore it is recommended to use large storage capacity hard drives.
WARNING
Even hard drives by the same manufacturer, of the same model, and claiming the
same rated capacity may actually carry different block numbers meaning that their
capacity may not be exactly the same.
When configuring hard drives into a RAID array, you may use a slightly smaller
capacity as the “
Maximum Disk Capacity
” in each individual hard drive. The
configuration option can be found in the interface-specific firmware manual that
came with your enclosure.
Profile:
The drive trays and bays of the system are
designed for 2.5” or 3.5” hard
drives, depending on the system model.
Drive type:
The system uses SATA
2.5” or 3.5” hard drives. Please ensure that you
purchase the correct hard drives.
NOTE
If you prefer using SATA hard drives in attached expansion enclosures, make sure
you also purchase MUX kits.
