Replication Partner Requirements

Replication partners must meet the following requirements:

• Network connectivity, with adequate network bandwidth between the groups, in addition to full IP routing. A slow network link between the partners may result in long replication times. You may want to use manual transfer replication for the first replication if you have a slow network link and a large amount of data to transfer.
• Sufficient space for replication. Volume replication consumes free space in the primary group, where the volume resides, and in the secondary group, where the replicas are stored. You will need more replication space if you increase the size of a volume, or if the volume reserve for a thin-provisioned volume grows automatically. In addition, recovering data from replicas may require additional space on the secondary group.
