Estimating Advanced Copy Source Capacity
This appendix describes the maximum usable Advanced Copy size.
The maximum copy source capacity for each copy type is shown in the table below.
The estimated values in the following tables are examples of typical Advanced Copy sessions (the maximum memory area required for Advanced Copy management is secured and the number of copy sessions is 400). Actual values can be calculated by using the procedure in "How to calculate the copy table size" of "Operating Procedure" in "Modify Copy Table Size" of "Web GUI User's Guide".
