Modifying the Migration Rate

Prerequisites

The running status of a SmartMove pair is Migrating, Paused, or Interrupted.

Procedure

1. Choose Resources > Dataflow > SmartMove.
2. Select one or more desired SmartMove pairs and click Modify Migration Rate.

   The Modify Migration Rate page is displayed.

   

   Unfold Selected Pairs. You can select a running status to list available pairs under this status and reselect pairs.

3. Set the default migration rate for the SmartMove pair. Possible values are Low, Medium, High, Highest, and Custom.
   • Low

     Migration takes a relatively long period of time. This value is used when the service load is heavy.

     The rate is less than or equal to 2 MB/s.

   • Medium

     Migration takes a relatively short period of time. This value is used when the service load is relatively heavy.

     The rate is less than or equal to 15 MB/s.

   • High

     Migration takes a short period of time. This value is used when the service load is relatively light.

     The rate is less than or equal to 60 MB/s.

   • Highest

     Migration takes the shortest period of time. This value is used when the service load is light.

     The rate is less than or equal to 500 MB/s.

   • Custom

     You can set the migration rate as required. The value ranges from 1 MB/s to 1024 MB/s.

   

   • The migration rate is affected by the volume read and write performance and the link bandwidth.
   • Higher migration rates impose greater impact on host service performance. If you choose Highest, the SmartMove task may be interrupted due to heavy service load. You are advised to use the highest rate when the host service is not running.

4. Click OK.
