Installing The Hard Drives - Infortrend EonStor GSe Pro 208 Hardware Manual

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) hard drives in drive bays 1 and 2 when setting up the
system.
NOTES:
•
•
Hard drive trays as hot-swappable components
The hard drive trays are hot-swappable components. You can replace a hard disk 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 speeds (RPM). This 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!
•
•
• Profile
The drive trays and bays of the system are designed for 2.5-inch SATA SSDs and 3.5-inch SATA
HDDs.
• Drive type
The system uses SATA-III 6 Gbps hard drives with up to 3 TB storage space per drive.

EonStor GSe Pro 200 Series Hardware Manual
The hard drives are purchased separately.
Refer to section Hard drive designation for the order of the drive trays.
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.
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.
