).
•
Z: The number of slots that can be managed by a differential table:
.
NOTE:
Round the result of the calculation up to the nearest whole number.
For example, if a volume has the emulation type 3390-3, and 3339 cylinders, calculate the total number of
differential tables with the following equation:
.
When you round 0.81836 up to the nearest whole number, it becomes 1. Therefore, the total number of
differential tables for one migration plan is 1 when emulation type is 3390-3.
The following table shows the number of the control cylinders according to the emulation type.
The following table shows the number of the control cylinders according to the emulation type.
