What is the most storage-efficient configuration mode for a virtual machine disk in Huawei FusionCompute?

The most storage-efficient configuration mode for a virtual machine disk in Huawei FusionCompute is the Streamline mode. This mode is specifically designed to minimize the use of storage resources by implementing a thin provisioning strategy. In Streamline mode, the virtual disk only consumes disk space based on actual usage rather than allocating the full size of the disk from the outset. This efficient use of space reduces the amount of storage needed, allowing for better management and allocation of resources within a cloud environment.

In contrast, other modes such as General, Independent-persistent, and Independent-non-persistent typically allocate more space upfront or manage storage differently, which can lead to increased storage consumption. For instance, Independent-persistent mode preserves changes made to the disk, potentially using more storage over time, while Independent-non-persistent mode does not retain changes, but still functions differently compared to Streamline. Hence, when considering storage efficiency, Streamline stands out as the optimal choice within FusionCompute’s disk configuration options.
