Drive Enclosure Overview

Drive Enclosures are used as back-end storage for the Oracle Flash Storage System. The Oracle FS System can be configured for as many as 30 Drive Enclosures. The two types of Drive Enclosure are the DE2-24P Drive Enclosure and the DE2-24C Drive Enclosure. Both Drive Enclosure types can co-exist in the same system.

Drive Enclosure are high-availability, serial-attached SCSI (SAS-2) storage enclosures. The DE2-24P Drive Enclosure has a 2U chassis that supports 24 small form factor (SFF), 2.5-inch (6.35-cm) hard disk drives (HDDs). The DE2-24P Drive Enclosure also supports configurations with seven, 13, or 19 solid state drives (SSDs). The DE2-24C Drive Enclosure has a 4U chassis that supports 24 large form factor (LFF), 3.5-inch (8.89-cm) HDDs.

The following figures show the front of the DE2-24P Drive Enclosure and the DE2-24C Drive Enclosure.

Both types of Drive Enclosures have the following physical configuration:

Two hot-serviceable I/O modules with two interface slots that comply with the Storage Bridge Bay (SBB) standard
Two hot-serviceable 580W power cooling modules with dual load-sharing power supplies and integrated fans
19-inch rack‑compatible enclosure
Front access to all drives
Back access to the I/O modules and the power cooling modules
LEDs with status information for the I/O modules, the drives, and the power cooling modules
