Overview of Disk Shelves

Oracle disk shelves are high-availability serial attached SCSI (SAS) devices that provide
expanded storage. The main components are hot-swappable, including drives, I/O Modules
(IOMs) or SAS Interface Module (SIM) boards for connecting to controllers and other disk
shelves, and dual load-sharing power supply with fan modules. This provides a fault-tolerant
environment with no single point of failure. Component status is indicated with lights on the
disk shelf, and in the Maintenance > Hardware screen of the BUI.

six HDD-only or SSD-capable disk shelves, combined in
any order.
The 7320 single and cluster controller configurations
allow a single chain of one to six disk shelves. Any
combination of disk-only and Logzilla-capable shelves
may be combined within the chain in any order. The
cabling configurations are unchanged. Half-populated shelf
configurations are not supported.
The 7120 standalone configurations allow a single chain of
1 or 2 disk shelves. Write-optimized (Logzilla) SSDs are
not supported in the expansion storage for the 7120. The
disk shelves must be fully populated with 24 HDDs. Half-
populated shelf configurations are not supported.
