If the calculated number of bitmap areas exceeds the total number of
bitmap areas in the storage system, the number of pairs that can be
created will be limited.
To calculate the maximum number of pairs that you can create:
The maximum number of pairs that you can create =
( ↓ (the total number of bitmap areas in
the storage system ÷ Number of bitmap
areas) ↓ )
The ↓…↓ symbols around a value indicate that the value should be rounded down to the nearest whole number..
Note: The maximum number of pairs that you can create cannot exceed
37,768.
