Abstract
A disk array includes SSD of different page sizes and a virtual disk is constructed based on the SSDs of different page sizes. The constructed virtual disk formed by a hybrid-page chunk which includes a large-page chunk, a small-page chunk, and the small-page chunk, is not provided for the host for use, and is only used to migrate data corresponding to the large-page chunk. Based on the virtual disk formed by the hybrid-page chunk, the data with a large granularity can be stored in the SSD with a large page size, and data with a small granularity is migrated to the SSD with a small page size.
