The tables in this section show the sizes for DATA, RECO, REDO, and FLASH disk groups on various configurations of Oracle Database Appliance.
Each table row has values for either normal or for high redundancy levels. The disk capacities shown in the tables vary, because they are derived by converting disk hardware terabytes (based on 1 kilobyte equals 1,000 bytes) into data storage terabytes (based on 1 kilobyte equals 1,024 bytes).
The space calculated with a storage expansion shelf approximately doubles the space mentioned in these tables.
Note:
The storage expansion shelf can only be used with Oracle Database Appliance X3-2, X4-2, and X5-2.

Note:
For non-CDB databases, the REDO disk group has 50% free disk space.
For CDB databases, an Oracle ACFS mount point is created per CDB database, based on the template log file size. If this is a Single Instance (SI) database, then multiply by 3. If the is an Oracle RAC database, then multiply by 4.
Accelerator volume size is 0.4% of the database DATA Oracle ACFS file system size and shared REPO Oracle ACFS file system size.
