Adjusting Cloud Disk Performance

Last updated: 2022-09-30 14:21:22

    The performance of a cloud disk depends on its capacity. You can improve the performance to the maximum level by adjusting its capacity. After the basic performance of an enhanced SSD reaches the ceiling, you can configure and adjust extra performance to achieve even higher performance anytime when prerequisites are met. For more information, see Enhanced SSD Performance.

    Note
    • Currently, only Enhanced SSD supports independent performance adjustment.
    • The extra performance can be independently adjusted only after the basic performance reaches the ceiling.
    • The performance adjustment will not affect your cloud disks or businesses.
