CBS allows you to create a cloud disk and attach it to any CVM in the same availability zone. The cloud disk is identified and used by the CVM through block storage device mapping. Once created, the cloud disk can reach its maximum performance without prefetch.
You can create different types of CBS cloud disks based on business needs. For more information about CBS disk types, see CBS Types.
