Differential tables and pair tables are required to create SI pairs. Differential tables are tables that manage the differential bitmaps, and pair tables are tables that contain the information needed to manage SI pairs. Create enough tables to handle the SI pairs you plan to create.

The storage system uses a single pair table for up to 36 differential tables.
