Populating drawers with DDICs
The 5U84 enclosure does not ship with DDICs installed. Before populating drawers with DDICs, ensure that you adhere to the
following guidelines:
● The minimum number of disks that are supported by the enclosure is 28, 14 in each drawer.
● DDICs must be added to disk slots in complete rows (14 disks at a time).
● Beginning at the front of each drawer, install DDICs consecutively by number, and alternately between the top drawer and
the bottom drawer. For example, install first at slots 0–13 in the top drawer, and then 42–55 in the bottom drawer. After
that, install slots 14–27, and so on.
● The number of populated rows must not differ by more than one row between the top and bottom drawers.
● Hard disk drives (HDD) and solid-state drives (SDD) can be mixed in the same drawer.
● HDDs installed in the same row should have the same rotational speed.
● DDICs holding 3.5" disks can be intermixed with DDICs holding 2.5" disks in the enclosure. However, each row should be
populated with disks of the same form factor (all 3.5" disks or 2.5" disks).
The following figure shows a drawer that is fully populated with DDICs:
● See 3.5" disk drive in a DDIC on page 13 for the DDIC holding the 3.5" disk
● See 2.5" drive in a 3.5" DDIC with a hybrid drive carrier adapter on page 14 for the DDIC holding the 2.5" disk with 3.5"
