NOTE:
Customers select a chassis type and drives separately. All empty drive slots in the 2U chassis
must have drive blanks installed.
The 2U chassis supports the following form factors:
•
2U12 chassis configured with 12 LFF disks (see
on page 16) as follows:
• Twelve 3.5” SAS LFF disk drives, held horizontally
• Twelve 3.5” SATA LFF disk drives, held horizontally
•
2U24 chassis configured with 24 SFF disks (see
on page 16) as follows:
• Twenty-four 2.5” SAS SFF disk drives, held vertically
• Twenty-four 2.5” SATA SFF disk drives, held vertically
•
2U12 empty chassis with midplane and module runner system: see
•
2U24 empty chassis with midplane: see
The chassis has a 19-inch rack mounting that enables it to be installed onto standard 19-inch racks
and uses two EIA units of rack space (3.5”) for a 2U chassis.
•
The midplane PCB can support either 12 or 24 drive connections.
•
There are either 12 or 24 drive slots at the front of the chassis, in horizontal (12) or vertical (24)
orientation, as defined by the chassis variant.
• See also
and
• Each drive slot holds a plug-in drive carrier module that can hold these drive types, dependent
upon the chassis type:
•
At the rear, the chassis assembly can hold a maximum of two PSUs and two RAID controllers or
SBB-compliant expansion IOMs.
