Oracle Storage Drive Enclosure DE3-24
This section introduces the front and rear panel components of the Oracle Storage Drive Enclosure DE3-24P and Oracle Storage Drive Enclosure DE3-24C disk shelves.
Oracle Storage Drive Enclosure DE3-24P Disk Shelf
Oracle Storage Drive Enclosure DE3-24P is a 2U chassis that supports 24 2.5'' SAS-3 drives. The high-performance HDDs provide reliable storage, and the SSDs provide accelerated write operations. This disk shelf features dual, redundant I/O Modules (IOMs), and dual power supply with fan modules.
Oracle Storage Drive Enclosure DE3-24P Drive Locations (Front View)
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 DE3-24 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.
