Both of the 5U84 Storage Shelf chassis include a set of common internal core
components, along with a set of plug-in modules.
The core components include:
■
Two sliding disk drawers that contain Disk Drive In Carrier (DDIC) modules
■
A front operations panel
■
A front bezel
■
A mid-plane printed circuit board (PCB) to connect the RAID controller on the
5U84 Primary Storage Shelf. It is also used to connect the Expansion I/O
modules on the 5U84 Expansion Storage Shelf.
For example, the 5U84 Primary Storage Shelf uses two redundant RAID
Controller modules that plug into its internal mid-plane PCB. The 5U84 Expansion
Storage Shelf uses two redundant Storage Bay Bridge 2.1-compliant Expansion
I/O modules that plug into its internal mid-plane PCB.
In addition to the core components, the storage shelves also incorporate the following
plug-in modules:
■
Two redundant RAID Controller modules (
5U84 Primary Storage Shelf only
)
■
Two redundant Expansion I/O modules (
5U84 Expansion Storage Shelf only
)
■
Two redundant Power Supply Units (PSUs)
■
Five Fan Modules
■
Up to 84 Disk Drive In Carrier (DDIC) modules with drives installed
■
A rail kit for rack mounting
The 5U84 Primary Storage Shelf and the 5U84 Expansion Storage Shelf each use
a 5U chassis. Each chassis contains two sliding disk drive drawers that are located
in the front of the storage shelf. Each drawer holds 42 Disk Drive In Carrier (DDIC)
modules. The DDIC modules are installed in the drive drawer slots, which hold a
total of 84 disk drives. Each DDIC module holds SAS3, 7200 rpm hard disk drives,
in either 4TB or 8TB capacities. The disk drives and the DDIC modules are
hot-swappable and can be replaced on-site while the storage shelf is operational.
Note:
Whether you use 4TB or 8TB disk drives in the storage shelves, each storage
shelf drawer must be populated with disk drives of the same capacities.
In each storage shelf, two disk drives are used as global hot spares. Four of the
disk drives provide storage space for a dedicated RAID 10 metadata volume group.
When 4TB disk drives are used, the storage shelf provides 7.27TBs of metadata
storage capacity. When 8TB disk drives are used, the storage shelf provides
15.75TBs of metadata storage capacity. The remaining disks are configured in a
