CAUTION:

When an MCU and RCU are connected via switches with a channel extender and

multiple remote copy paths are assembled, the majority of data to be transmitted might be
concentrated on particular switches, depending on the switch routing's configuration and settings.

journal groups use. Therefore, to achieve the desired data transfer speed, you must consider these
journal volume specifications.
