Assessing ShadowImage for Mainframe Requirements
This section describes the assessments about SIz operations, such as how many pairs you are
going to create or how to decide the settings like copy pace and paths.
Calculating Maximum Number of Pairs
When you create SIz pairs, resources called differential tables and pair tables will be required.
The number of available differential tables and pair tables in one storage system depends on
whether the additional shared memory is installed or not. There are several patterns of additional
shared memory for differential tables and pair tables, and you can choose any pattern you like.
