TrueCopy performance.
The following remote connection options affect how copy operations are performed:
- Number of minimum paths for a pair. You can find
detailed information in Minimum number of remote paths option
- RIO MIH Time, which is the waiting time from when copy starts until when it ends. This value applies to the slots which received the request of copying data from the local storage system to the remote storage system.
- Round trip time, which is the time limit for
copying data to the S-VOL. For more information, see Round trip time option.
