摘要： A virtualization system, upon judging that a write operation from a higher-level device is an operation to write in the format of the virtual volume, even when the write position of the write operation is in a virtual area different from a virtual area to which an allocated actual area has been allocated, if there is an unused area in the allocated actual area, writes management information to the unused area according to the write operation, and if there is no unused area in the allocated actual area, newly allocates an unallocated actual area, and writes management information to the newly allocated actual area according to the write operation.

摘要： The present invention allows the processing mode for write access operations to be set independently and respectively for prescribed units. The processing modes for handling write access are set previously for each of the volumes 6A and 6B. If the cache memory is functioning normally, write access operations to the respective volumes 6A and 6B are processed by means of an after-write method as illustrated in FIG. 1(a). If an abnormality has occurred in the cache memory, then write access operations to the volumes 6A and 6B are processed by means of a method previously selected from a write-through method as illustrated in FIG. 1(b) or a non-redundant storage type write-after method as illustrated in FIG. 1(c). By using different processing modes for write access, for each of the volumes 6A and 6B, it is possible to set a suitable processing mode respectively for each of the prescribed units, in accordance with the composition of the storage system, the operation configuration, and the like.

摘要： A storage controller of the present invention can input and output data even when the track size, which is the host management unit, is not consistent with the block size of the storage device. A boundary correction unit adds gap data corresponding to a gap size to data in a buffer memory so that the boundary of the track and boundary of the block inside the storage device match. A guarantee code is added to each logical block received from the host, and these guarantee code-appended blocks are stored in a cache memory. By providing a gap in the storage device every 116 extended logical blocks, the start position of the lead block of a track matches up with the start position of the logical blocks of the storage device.
