Enabling Performance-Based Autotuning for an Existing Boot Volume

Learn how to enable performance-based autotuning to automatically adjust an existing boot volume's performance between levels you specify.

    1. On the Boot Volumes list page, select the boot volume you want to work with. If you need help finding the list page or the boot volume, see Listing Boot Volumes.
    2. On the details page, select Edit.
    3. In the Volume size and performance section, select the Performanced based auto-tune slider so that it changes from Off to On.
    4. Specify a value for Default VPUs/GB. This is the minimum performance setting the volume will be adjusted to. The value must be a multiple of 10. The minimum value is 10 and the maximum value is 110. You can also use the VPUs/GB slider to specify the value.
    5. Specify a value for Maximum VPUs/GB. This is the maximum performance setting the volume will be adjusted to. The value must be a multiple of 10, and must be at least 10 VPUs/GB higher than Default VPUs/GB. The maximum value is 120 VPUs/GB. You can also use the VPUs/GB slider to specify the value.

    6. Select Save changes.

  • Use the oci bv boot-volume update command and specify the --volume-id, --compartment-id and --autotune-policies parameters to enable performance-based autotuning for an existing volume:

    oci bv boot-volume update --volume-id <volume_ID> --compartment-id <compartment_ID> --autotune-policies <auto-tune_policies_JSON>'

    For example:

    oci bv boot-volume update --volume-id ocid1.volume.oc1.phx.<unique_ID> --compartment-id ocid1.compartment.oc1.phx.<unique_ID> --autotune-policies '[{"autotune-type": "PERFORMANCE_BASED", "maxVpusPerGB": 50}]''

  • Run the UpdateBootVolume operation and specify the autotunePolicies attribute in the UpdateBootVolumeDetails resource to enable performance-based autotuning.
