2.2.3 Installing the hard drives
This section gives you an overview of the hard drive requirements, installation, and important notices
that you must take note.
NOTE:
The hard drives are purchased separately.
IMPORTANT!
•
Ensure to install the enclosure to the rack first before installing the hard drives to the enclosure’s
drive bay.
•
You must install at least four (4) hard drives for RAID 5 configuration or five (5) hard drives for RAID
6 configuration to create an initial volume.
Hard drive installation prerequisites
When purchasing hard drives, ensure to consider the following factors:
•
Capacity (Mb/Gb)
Purchase the hard drives that have the same capacity. This main storage uses the
least common
denominator
approach, which means that the maximum capacity used in each drive to create
a RAID array is the maximum capacity of the smallest drive. We strongly suggest to use large
storage capacity hard drives.
IMPORTANT!
• The hard drives may carry different block numbers, which means that the capacity may not be
the same even if they are of the same model with the same rate capacity made by the same
manufacturer.
•
When configuring the hard drives into a RAID array, you can use a smaller capacity as the
maximum disk capacity
in every hard drive. For configuration options, refer to the interface-specific
firmware manual that came with your enclosure.
•
Profile
The drive trays and bays of the system are designed for 2.5-inch hard drives.
•
Drive type
The system uses SAS, near-line SAS, and SATA hard drives.
IMPORTANT!
• Ensure that you purchase the correct hard drives.
• If you prefer using SATA hard drives in the attached expansions, ensure that you purchase MUX
kits.
