NOTE
For asynchronous remote replication, it is advised to use the BCManager eReplication disaster recovery
software if the synchronization interval is longer than 15 minutes. Because a host's cached data may not be
completely delivered to the storage system when synchronization is triggered, data synchronized to the
remote end may be inconsistent with that at the local end. BCManager eReplication can ensure data
consistency between hosts at both ends. For details about BCManager eReplication, see the related User
Guide and Compatibility List.
