Create a Bandwidth Control

Create a Bandwidth Control to manage the bandwidth used to send replication and Live Volume data between local and remote Storage Centers. A Bandwidth Control is also required to create a Live Migration or One Time Copy of a volume.

1. Click the HOME menu.
   The Unisphere CentralHome page is displayed.

   If a Storage Center is selected from the drop-down list in Unisphere Central, click (Home).

2. From the Data Mobility menu, click Bandwidth Controls.
3. Click (New).
   The new Bandwidth Control dialog box opens.
4. Configure the attributes of the Bandwidth Control.
   1. Select the Storage Center to which to apply the definition.
   2. In the Name field, type a name for the Bandwidth Control.
   3. In the Link Speed field, specify the speed of the link in Mbps or Gbps.
5. Configure bandwidth limits for replications and Live Volumes that is associated with the Bandwidth Control.
   1. Select the Use Limiting Schedule check box.
   2. Limit bandwidth for a time range by clicking the first 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 Bandwidth Control. This condition can cause synchronous replications to become unsynchronized. Live Migrations that use only blocked Bandwidth Controls cannot be completed.
   3. Limit bandwidth for other time ranges as needed.
6. Click OK.
