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, see Creating a Block Volume. The default volume performance setting for existing and new block volumes is Balanced.

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.

    1. On the Block Volumes list page, find the volume that you want to work with. If you need help finding the list page or the volumes, see Listing Volumes.
    2. From the Actions menu (three dots) for the volume, select Edit.
    3. In the Edit block volume (or Edit volume) panel, for VPUs type, select the performance setting that you want.
      You can also specify the VPUs/GB value for the performance setting in Default VPUs/GB.
    4. Select Save changes.

  • 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.
