The Successfully started replication dialog is displayed. Adding a Cascaded Replica To add a cascaded replica to an existing replication relationship, complete the following steps. 1. Select Storage→ Replication. 2. On the Replication page, select the replication relationship for which you want to add a cascaded replica, and then click Edit. The Edit Replication dialog opens. 3. Under Cascaded Replica Container, click Select a container from the remote system to select the container you will be using for the cascaded replica. 4. Enter the logon credentials of the remote system. 5. Click the Retrieve Remote Container button, and, in the drop-down list, select a remote container from the list of available containers. 6. Under Replica > Cascaded Replica Container, select one of the following Encryption options: None, 128-bit, or 256- bit. 7. For Bandwidth, select the Bandwidth Speed Rate as Default or specify a rate. NOTE: Bandwidth is the replication bandwidth limit that you can set as Kibibytes per second (KiBps), Mebibytes per second (MiBps), Gibibytes per second (GiBps), or as an unlimited bandwidth (default). The minimum allowed replication bandwidth setting that you can configure is 192 Kbps. 8. Click Save Replication to save your changes.
