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.
IMPORTANT!
You must install at least two (2) drives in bays 1 and 2 to initially set up the system.
NOTES:
• The drives are purchased separately.
• Refer to section
for the order of the drive trays.
Drive trays as hot-swappable components
The drive trays are hot-swappable components. You can replace a drive without shutting off the system.
Use a supported RAID system when configuring your hard drives. See the following RAID configuration
below:
•
RAID 5 allows one hard drive to fail at any given time without losing data.
•
RAID 6 allows two hard drives to fail simultaneously in any given time without losing data.
NOTE:
Refer to
EonStor GSe Pro Software Manual
for RAID configuration details.
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 and rotation speed. RAID arrays use
least
common denominator
approach, which means that the maximum capacity used in each drive to
comprise a logical configuration is the maximum capacity of the smallest drive. We strongly suggest
to use large storage capacity 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 SATA SSDs or 3.5-inch SATA
HDDs.
•
Drive type
The system uses SATA-III 6 Gbps drives with up to 3 TB storage space per drive.
IMPORTANT!
• Ensure that you purchase the correct hard drives. Download the
compatible drives and other components.
•
To prevent accidents and technical mishaps, ensure to place the system first into a cool, dry, and
secured place before installing the hard drives into the system.
• DO NOT shift or tilt the system once it is powered on to avoid damaging the hard drives.
• DO NOT remove two hard drive trays from the system simultaneously.
