摘要： In one embodiment of an image forming apparatus according to the invention, an overwrite-block specifying device specifies equal size blocks so that a storage area in a data storage device is divided into consecutive equal size blocks to be overwritten with overwrite data. The data storage device includes an image data storage area configured to store encrypted image data on a page-by-page basis. An overwrite-data specifying device specifies the value of the overwrite-data whose size is smaller than that of the equal size block. A data erase control device overwrites the equal size blocks with the value of the overwrite-data, on a block-by-block basis.

摘要： A physical storage area that is allocated to an unused area of a virtual volume is removed. A management unit sends a request to a server computer to make every piece of data stored in a first logical volume migrate to a second logical volume. The server reads all the data out of the first logical volume and writes the data in the second logical volume. A storage system that includes the first logical volume and the second logical volume allocates a physical storage area to an area of the second logical volume where the data is to be written, and writes the data in the allocated physical storage area. The storage system then deletes the first logical volume.

摘要： The present invention provides effective use of a storage resource in a system where a storage area of a logical volume is dynamically extended and reduced. In an information processing system including a management device communicably connected to a storage device that can dynamically change a storage capacity of a virtual volume allocated to a host computer, when a used amount of a certain storage pool exceeds a threshold set in the storage pool, the management device sends to the storage device, an instruction to migrate a predetermined number of virtual volumes, sequentially selected in ascending order of capacity increasing rate, so that another storage pool different from the certain storage pool may be used as a creation source. At this time, as a migration destination, the management device uses, the storage pool having, for example, an attribute of the storage resource identical to that of the certain storage device.
