Internal storage
The system can manage a combination of internal and external storage and represents all the detected storage as drives. Internal storage is provided by drives that are inside control enclosures and expansion enclosures.
You can select to have the system automatically assign all detected internal drives to pools, or select to customize the configuration. When the system automatically assigns drives, pools are created based on the available drive classes and recommended array configurations. In this case, the system might not use all available drives if they do not meet configuration recommendations. If you choose to customize, you can adjust the configuration based on the number of drives and drive criteria. These arrays are presented as MDisks, which can be added to pools.
