Changing the Performance of an Existing Block Volume

Learn how to dynamically configure the performance level for a block volume.

  • You can change the default setting when you create a new block volume. For more information, seeCreating a Block Volume. The default volume performance setting for existing and new block volumes is Balanced.

    1. Open the navigation menu  and select Storage. Under Block Storage, select Block Volumes.

    2. Select the block volume that you want to change the performance for.

    3. Select Edit.
    4. Using the VPUs/GB slider, specify the performance setting you want to change to. You can also specify the VPUs/GB value for the performance setting in Default VPUs/GB.

    5. Select Save changes.

    When you create an instance, the volume performance setting for the instance's boot volume is set to Balanced. You can change this setting to Higher Performance or UHP (Ultra High Performance) after the instance has been launched.

  • Run the oci bv volume update command and specify one of the following volume performance unit (VPU) amounts in the vpus-per-gb parameter to update a block volume's elastic performance setting:

    • 0: Represents the Lower Cost setting. Applies to block volumes only.
    • 10: Represents the Balanced setting. Applies to both block volumes and boot volumes.
    • 20: Represents the Higher Performance setting. Applies to both block volumes and boot volumes.
    • 30 to 120: Represents the Ultra High Performance. Applies to both block volumes and boot volumes.

    For example:

    oci bv volume update --volume-id <volume_ID> --vpus-per-gb 20

  • Run the UpdateVolume operation and specify one of the following volume performance unit (VPU) amounts in the vpusPerGB attribute for the UpdateVolumeDetails resource to update a block volume's elastic performance setting:

    • 0: Represents the Lower Cost setting, applies to block volumes only.
    • 10: Represents the Balanced setting, applies to both block volumes and boot volumes.
    • 20: Represents the Higher Performance setting, applies to both block volumes and boot volumes.
    • 30 to 120: Represents the Ultra High Performance setting, applies to both block volumes and boot volumes.
