Replication Icons

The icons displayed for replications on the Storage tab of the Storage view indicate whether the volume is the source or destination of the

replication.

Icon Description

The volume is the source for a replication to a remote Storage Center or the source volume in a copy, mirror, or migrate

relationship.

The volume is the destination for a replication from a remote Storage Center.

Simulating Replications

Simulated replications allow you to estimate requirements for replication and determine an optimal balance between volumes, snapshot

schedules, bandwidth schedules, and your recovery plan.

NOTE: For user interface reference information, click Help.

Simulate a Replication

Run a synchronous replication simulation to verify bandwidth requirements and optimal data movement.

1 Click the Storage view.

2 In the Storage pane, select the Storage Center that hosts the volume for which you want to simulate replication.

3 In the Summary tab, click Actions, then select Replication→ Simulate Replicate Volumes.

• If one or more QoS denitions exist, the Create Simulation Replication wizard appears.

• If a QoS denition has not been created, the Create Replication QoS wizard appears. Use this wizard to create a QoS denition

before you congure replication.

4 In the Simulate Volume(s) to Replicate table, select the volume(s) for which you want to simulate replication, then click Next. The

wizard advances to the next page.

5 (Optional) In the Replication Attributes area, modify default settings that determine how replication behaves.

6 Click Next. The wizard advances to the next page.

7 (Optional) To modify replication attributes for an individual simulated replication, select it, then click Edit Settings.

8 Click Finish. Use the Replications tab on the Replications & Live Volumes view to monitor the simulated replication(s).
