Cloud disk performance is generally related to its capacity. You can adjust the capacity to achieve higher performance when the disk has not reached its maximum performance. Specifically, Enhanced SSD cloud disks support breaking through the basic performance limit by configuring extra performance after reaching the maximum value of basic performance. You can configure and adjust the extra performance as needed when the conditions are met. For more information, please refer to Enhanced SSD Cloud Disk Performance Description.
Note
Currently, only Enhanced SSD Cloud Disks support independent performance adjustments.
Basic Performance must reach its maximum value before Additional Performance can be independently adjusted.
The performance adjustment will not affect your cloud disks or businesses.
