Creating and Managing Replication Quality of Service Denitions
Replication Quality of Service (QoS) denitions control how bandwidth is used for replications, Live Volumes, and Live Migrations.
Create a QoS denition before you create a replication, Live Volume, or Live Migration.
Create a QoS Denition
Create a QoS denition to control how bandwidth is used to send replication and Live Volume data between local and remote
Storage Centers. A QoS denition is also required to create a Live Migration of a volume.
Prerequisite
The Storage Center for which you want to congure a QoS denition must be added to Storage Manager.
Steps
1. Click the Replications & Live Volumes view.
2. Click the QoS Nodes tab.
3. In the right pane, click Create QoS Node. The Create Replication QoS wizard appears.
4. Select the Storage Center for which you want to create a QoS node, then click Next. The Create page appears.
5. Congure the attributes of the QoS denition.
a. In the Name eld, type a name for the QoS denition.
b. In the Link Speed eld, specify the speed of the link in megabits per second (Mbps) or gigabits per second (Gbps).
c. Select the Bandwidth Limited check box, then click Finish. The wizard closes and the Edit Replication QoS Schedule
dialog box appears.
6. Congure bandwidth limits for replications and Live Volumes associated with the QoS denition.
a. Limit bandwidth for a time range by clicking the rst cell in the range and dragging to the last cell in the range, then right-
click the selection and select the percentage of available bandwidth that can be used.
NOTE: If you select Blocked for a time range, no data is transferred during that period for all replications, Live
Volumes, and Live Migrations that are associated with the QoS node. This can cause synchronous replications to
become unsynchronized. Live Migrations that use only blocked QoS nodes cannot be completed.
b. Limit bandwidth for other time ranges as needed.
7. When you are nished, click OK.
Rename a QoS Denition
Use the Edit Settings dialog box to rename a QoS Denition.
1. Click the Replications & Live Volumes view.
2. Click the QoS Nodes tab, then select the QoS denition.
3. In the right pane, click Edit Settings. The Edit Replication QoS dialog box appears.
4. In the Name eld, type a name for the QoS denition.
5. Click OK.
Change the Link Speed for a QoS Denition
Use the Edit Settings dialog box to change the link speed for a QoS Denition.
1. Click the Replications & Live Volumes view.
2. Click the QoS Nodes tab, then select the QoS denition.
3. In the right pane, click Edit Settings. The Edit Replication QoS dialog box appears.
4. In the Link Speed eld, specify the speed of the link in megabits per second (Mbps) or gigabits per second (Gbps).
5. Click OK.
