Data organization management

Data ONTAP organizes the data in user and system files and directories, in file systems called volumes, optionally in qtrees, and optionally in Logical Unit Numbers (LUNs) in SAN environments. Aggregates provide the physical storage to contain volumes.

For more information, see the Data ONTAP Storage Management Guide and the Data ONTAP Block Access Management Guide for iSCSI and FCP.

When Data ONTAP is installed on an storage system at the factory, a root volume is configured as /vol/vol0, which contains system files in the /etc directory.
