The Copy Pace list allows you to select the copy pace (from Slower, Medium, or Faster) for
all pairs being added.
When the Preview List already holds some Add Pair operation settings, and you specify a
different copy pace for new pairs in the Add Pair dialog box, the copy pace for the existing
Add Pair settings displayed in the Preview List will be also changed. The latest copy pace
specified in the Add Pair dialog box is always reflected to the storage system.
If you specify Slower, the pace of initial copying will be slow, but you can minimizes the
impact of SIz operations on storage system I/O performance. If you specify Faster, the initial
copy operation completes as quickly as possible, but it will cause a large impact on the I/O
operation.

volumes, which is the maximum number of volumes that can be displayed on one page. It
remains dimmed when the total number of volumes defined in the storage system is less than
1,024 volumes.
