A method for managing storage data, a storage manager and a storage system, the method comprising: after receiving a data storage request every time, allocating m storage blocks for this data to be stored, wherein each storage block is used for representing a section of virtual address space, and each of the storage blocks is configured with an unique block number (S310); assigning n storage containers for the m storage blocks, wherein each storage container represents a section of physical storage space on a storage device (S320); updating a correlation between the storage blocks and the storage containers according to a correlation between the m storage blocks and the n storage containers, wherein the correlation between the storage blocks and the storage containers is used for recording a correlation between an allocated storage block and a storage container accommodating the allocated storage block (S330); and recording the block numbers of the m storage blocks into metadata of this data to be stored, wherein the block numbers of the m storage blocks are used as virtual addresses of this data to be stored (S340), thereby improving the disk space utilization rate. |
