About Veritas 5340 Appliance storage shelves
Veritas offers two external storage shelf models for the Veritas 5340 Appliance.
These include the:
Veritas 5U84 Primary Storage Shelf (required)
Veritas 5U84 Expansion Storage Shelf (optional)
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
Mid-plane printed circuit boards (PCB) that interface with controllers on the 5U84 Primary Storage Shelf and the 5U84 Expansion Storage Shelf.
In addition to the core components, the storage shelves also incorporate the following plug-in modules:
Two 16Gb Fibre Channel RAID controller modules (5U84 Primary Storage Shelf only)
Two Storage Bay Bridge 2.1-compliant Expansion I/O controller modules (5U84 Expansion Storage Shelf only)
Two 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 SAS-3, 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 storage group that uses RAID 6 disk array technology. These disks are used for MSDP and AdvancedDisk data storage purposes. Depending on the storage configuration you purchase, the Appliance storage system supports up to 1,920TiBs of usable data storage space.
Note:
RAID10 is also known as RAID 1+0. It combines disk mirroring and disk striping to protect data.
