Cloud disk performance is typically related to cloud disk capacity. You can achieve higher performance by adjusting the capacity when the cloud disk has not reached its maximum performance. Performance of an Enhanced SSD can exceed the baseline performance limits by configuring additional performance after the maximum baseline performance is reached. You can configure additional performance as needed and adjust it at any time when conditions are met.
Note:
- Currently, only Enhanced SSDs support independent performance adjustment.
- Only when the benchmark performance has reached its maximum value can additional performance be adjusted independently.
- During the process of adjusting cloud disk performance, business operations are not affected and can run normally.
