It is typical for the target DXi to require additional disk space for replication data compared to the

Deleting a Replication Source
Delete a system from the list of replication sources if it will no longer send replicated data to the DXi6900.
After the source system is deleted, the DXi6900 will no longer accept replicated data from that system.
To delete a replication source:
1. Under
Source DXis
, select one or more sources to delete.

Changing the Maximum Number of Snapshots
During scheduled or manual data replication, the DXi6900 receives a snapshot from the source system. A
snapshot contains all of the data necessary to fully recover or failback a NAS share or VTL partition to the
