Infortrend DS 3024UB - Installing Hard Drives

2-7EonStor DS 3000 Series 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.
NOTE: The hard drives are purchased separately.
IMPORTANT!
• Ensure to install the enclosure to the rack rst before installing the hard drives to the enclosure’s
drive bay.
• You must install at least four (4) hard drives for RAID 5 conguration or ve (5) hard drives for RAID
6 conguration 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 SAN storage use 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 conguring the hard drives into a RAID array, you can use a smaller capacity as the
maximum disk capacity in every hard drive. For conguration options, refer to the interface-specic
rmware manual that came with your enclosure.
• Prole
The drive trays and bays of the system are designed for 2.5-inch or 3.5-inch hard drives, depending
on your EonStor storage system.
• Drive type
The system uses 12 Gbps SAS, SATA, and near-line 2.5-inch and 3.5-inch 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.
