Oracle Storage Drive Enclosure DE2-24

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

DE2-24 Disk Shelf

The 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.

Read-optimized cache SSDs can also be installed in the DE2-24P 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.
