Oracle Storage Drive Enclosure DE2-24

This section introduces the front and rear panel components of the Oracle Storage Drive Enclosure DE2-24P and Oracle Storage Drive Enclosure DE2-24C disk shelves.

Oracle Storage Drive Enclosure DE2-24P Disk Shelf

Oracle Storage Drive Enclosure DE2-24P is a 2U chassis that supports 24 2.5" SAS-2 drives. The high-capacity HDDs provide reliable storage. The SSDs provide accelerated write operations, and for some controllers, read-optimized cache operations. This disk shelf features dual, redundant I/O Modules (IOMs), and dual power supply with fan modules.

Up to four write-optimized log SSDs are supported per disk shelf. Log devices should be populated in order of slots 20, 21, 22, and 23.

External Read Cache Devices - Read cache devices, installed in Oracle Storage Drive Enclosure DE2-24P disk shelves, are external to the controller and referred to as external second level adaptive replacement cache (EL2ARC). When a cluster takeover occurs, read cache remains persistent and sharable between controllers, enabling read performance to be sustained. For slot configuration details and minimum software requirements, see Disk Shelf Configurations.
