ASR-5300I Series Hardware User Manual 18
2.4.3 Components Requiring Installation
Users must install the following components:
 The enclosure itself (please refer to the Slide Rail Kit Installation Guide)
 Hard drives
 Cabling
 CBM, if purchased separately as an optional accessory
2.5 Hard Drive Installation
The installation of hard drives should only occur after the enclosure has been
rackmounted.
2.5.1 Hard Drive Installation Prerequisites
Hard drives should be purchased separately. 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, we recommend using large storage capacity hard drives.
Profile: The drive trays and bays of the system are designed for 3.5” hard drives.
Drive Type: The system uses SAS (3Gbps or 6Gbps), SATA, and Nearline 3.5” hard
drives. Please ensure that the correct hard drives are purchased.
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, use a slightly smaller
capacity as the “Maximum Disk Capacity” in each individual hard drive.
The configuration options are explained in the interface-specific firm-
ware manual provided with the enclosure.
Note! If you use a dual-controller RAID system and prefer using SATA hard
drives in the enclosure or in the attached JBODs, ensure you also pur-
chase MUX kits.
