Oracle Storage Drive Enclosure DE2-24P
The Oracle Storage Drive Enclosure DE2-24P is a 2U chassis that supports 24 2.5" SAS-2
devices. The high-performance HDDs provide reliable data storage. SSDs provide read-
optimized cache and write-optimized log operations. This disk shelf also features dual,
redundant I/O Modules (IOMs), and dual power supplies with integrated fan modules.
External Read Cache Devices - Read cache devices, installed in 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” on page 286.
