Checking the performance of remote copies
TIP:
You can check the performance of remote copies when system operation uses asynchronous remote
copy functionality. See “About performance monitoring” on page 293 for more information.
For details on how to check performance of remote copies, see the following:
• “Checking buffer usage (pools and journal groups)” on page 297.
• “Checking buffer usage (sidefiles and journal volumes)” on page 297.
• “Checking write delay time (C/T Delta) for each copy group” on page 295.
Checking performance workflow (remote copies)
The following figure shows the flow of tasks for checking the performance of remote copies.
Monitoring transfer delay state of remote copies
This module describes how progress of volume replication functions are monitored:
• About copy progress, page 294
• Viewing copy progress, page 295
• Checking write delay time (C/T Delta) for each copy group, page 295
About copy progress
Copy progress is a value that indicates the progress of the volume replication functions being executed
by the storage system. The copy progress (copy pair matching rate) or differential-bitmap matching
