When you use an enhanced SSD (ESSD) AutoPL disk, you can enable or disable the performance provision and performance burst features for the disk based on your business requirements to reduce costs. After the performance provision feature is enabled for the disk, you can modify the provisioned IOPS to improve disk performance without changing the disk size. This topic describes how to modify the performance configurations of an ESSD AutoPL disk.
Usage notes
When you modify the performance configurations of an ESSD AutoPL disk, take note of the following items:
After the provisioned IOPS of the disk is modified, the provisioned throughput and total throughput of the disk change simultaneously.
For information about the formula used to calculate the IOPS and throughput of an ESSD AutoPL disk, see the Disk specifications section in the "ESSD AutoPL disks" topic.
The new performance configurations of the disk take effect immediately after the configurations are modified.
The configurations of an ESSD AutoPL disk can be modified up to two times within 24 hours.
Billing
If you enable the performance provision and performance burst features for a disk or change the provisioned IOPS of the disk, bills are generated based on the new disk configurations. We recommend that you modify the performance configurations of the disk based on your business requirements. For more information, see Block storage devices.

Modify the provisioned performance of an ESSD AutoPL disk
You can change the configurations of an ESSD AutoPL disk to enable or disable performance provision for the disk or modify the provisioned IOPS of the disk.
Log on to the ECS console.
In the left-side navigation pane, choose .
In the top navigation bar, select the region and resource group to which the resource belongs.
Find the disk whose configurations you want to modify. In the Actions column, choose
> Change Category. In the Change Disk Configurations dialog box, select ESSD AutoPL Disk from the New Disk Category drop-down list and then specify the provisioned IOPS of the disk.
NoteIf you set the provisioned IOPS to 0, the performance provision feature is automatically disabled for the ESSD AutoPL disk.
Confirm the configuration fees and click Confirm.
Enable or disable performance burst for an ESSD AutoPL disk
By default, performance burst is enabled when you create an ESSD AutoPL disk. You can disable performance burst as needed. After an ESSD AutoPL disk is created, you can perform the following operations to enable or disable performance burst for the ESSD AutoPL disk when you modify its attributes.
Log on to the ECS console.
In the left-side navigation pane, choose .
In the top navigation bar, select the region and resource group to which the resource belongs.
Find the ESSD AutoPL disk that you want to manage and choose
> Modify Attributes in the Actions column. In the Modify Disk Properties dialog box, select or clear Start for Performance Burst as needed.
Click Confirm.
