    Abstract: A second virtual volume having a plurality of second virtual areas is a clone of a first virtual volume having a plurality of first virtual areas. A first real area is allocated from a pool of real areas and based on storage devices to the first virtual volume. A storage controller allocates a second real area to the second virtual area before a write occurs in the second virtual area corresponding to the first virtual area to which the first real area is allocated. A physical area is allocated to a logical area corresponding to the first real area in each storage device, and data based on user data stored in the first real area is stored in the physical area. Each storage device allocates the physical area allocated to the logical area corresponding to the first real area to a logical area corresponding to the second real area.

    Abstract: A storage system is adapted for efficiency by defining beforehand a first size, which is the maximum data that can be read at one time, a second size, which is equal to or less than the first size, and a third size, which is a factor of the first size. A controller provides a virtual volume comprising a plurality of virtual pages. Upon receiving a write request, the controller allocates a pool area comprising a plurality of stripes of the first size, stores the write request data in a cache, and when writing the data stored in the cache to the storage device, compresses the data in accordance with the third size unit, selects a storage area in accordance with the second size unit, and writes the compressed data to the selected second size storage area sequentially from the start address of a free area without leaving spaces therebetween.

    Abstract: A storage system 103 carries out first and second de-duplication processes in response to receiving a write request from a client. First, a determination is made as to whether a write target data item overlaps with any of the stored data items of a part of a stored data item group, which is a user data item group stored in a storage device 209, and if so, the write target data item is prevented from being stored in the storage device. Second, a determination is made as to whether a target stored data item, which is not finished being evaluated as to whether it overlaps with the stored data item in the first de-duplication process, overlaps with another stored data item, and if so, the target stored data item or the same data item overlapping with the target stored data item is deleted from the storage device 209.

    Abstract: The first storage apparatus provides a primary logical volume, and the second storage apparatus has a secondary logical volume. When the first storage apparatus receives a write command to the primary logical volume, a package processor in a flash package allocates first physical area in the flash memory chip to first cache logical area for write data and stores the write data to the allocated first physical area. And when the package processor receives journal data creation command form the processor, allocates the first physical area to second journal area for journal data without storing journal data corresponding to the write data.
