Configure your system so that primary system activity does not exceed the capacity of the recovery site storage control.
XRC supports configurations where many primary site storage controls can funnel their updated data to a single storage control on the recovery system. However, you must consider the number of copied primary volumes and the rate of write activity to these volumes in your overall work load evaluation for the configuration. An inadequate configuration can cause XRC to cancel the copy operation to one or more volumes, or even end the storage control session.
