Main components of a storage system

A storage system running Data ONTAP has a main unit, which is the device that receives and sends data. Depending on the platform, a storage system uses storage on disk shelves, storage arrays, or both.

The storage system consists of the following main components:

• The storage controller, which is the component of a storage system that runs the Data ONTAP operating system and controls its disk subsystem
• The disk shelves, which contain disk drives and are attached to a storage system
