Abstract: A method and apparatus for managing data access comprises: receiving a write request for writing data into one or more storage blocks; in response to determining that a storage block is unavailable, writing a part of the data into a virtual storage block corresponding to the storage block, the part of the data being required to be written into the storage block; and in response to determining that the storage block becomes available, copying the part of the data from the virtual storage block to the storage block. The embodiments of the present disclosure further disclose a corresponding apparatus. By introducing the virtual storage blocks in the data access, the embodiments of the present disclosure can realize the parallel data transfers of a plurality of writes and thus greatly improve the data writing performance of the system.
