Data ONTAP stores data on disks in disk shelves connected to storage systems or uses storage on storage arrays.
For native storage, Data ONTAP uses RAID-DP or RAID4 groups to provide parity protection. For array LUNs, Data ONTAP uses RAID0 groups to optimize performance and storage utilization. The storage arrays provide the parity protection for array LUNs. Data ONTAP RAID groups are organized into plexes, and plexes are organized into aggregates.
For more information about data storage management, see the Data ONTAP Storage Management Guide for 7-Mode.
