The Block Volume service's elastic performance feature enables you to dynamically configure the volume performance for block volumes and boot volumes, for more information, see Block Volume Elastic Performance.
Required IAM Service Policy
To use Oracle Cloud Infrastructure, you must be given the required type of access in a policy written by an administrator, whether you're using the Console or the REST API with an SDK, CLI, or other tool. If you try to perform an action and get a message that you don’t have permission or are unauthorized, confirm with your administrator the type of access you've been granted and which compartment you should work in.
You can only change the elastic performance configuration on three volumes concurrently per tenancy.
When changing volume performance for boot volumes, you can only select the Balanced or Higher Performance options.
Using the Console
The default elastic performance setting for existing block volumes or when you create a new block volume is Balanced. You can change the default setting when you create a new block volume, see Creating a Volume. You can also change the elastic performance setting for an existing block volume using the steps in the following procedure.
Use the volume update operation or the boot-volume update operation with vpus-per-gb parameter to update a block volume's elastic performance setting. The vpus-per-gb parameter is where you specify the volume performance units (VPUs). VPUs represent the elastic performance settings, with the following allowed values:
0: Represents Lower Cost setting, applies to block volumes only.
10: Represents Balanced setting, applies to both block volumes and boot volumes.
20: Represents Higher Performance setting, applies to both block volumes and boot volumes.
