DE3-24P Disk Shelf
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.

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
