This section introduces the front and rear panel components of the DE3-24P and DE3-24C disk shelves.
The 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. 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.
Read-optimized cache SSDs can also be installed in the DE3-24P disk shelf, for some controllers. For slot configuration details and minimum software requirements, see Disk Shelf Configurations in Oracle ZFS Storage Appliance Customer Service Manual.
