摘要： A virtual volume control unit allocates, upon detection of a write request for new data in a virtual volume to be accessed, an actual storage space of a physical medium existing in the same storage group to the virtual volume in accordance with volume capacity of the new data. A storage control unit stores the new data as actual data in the actual storage space of the physical medium allocated to the virtual volume. And a restoration control unit causes, upon detection of a fallback in data redundancy in the storage group, the actual data in a stored space among the actual storage spaces in the physical medium that caused the fallback to be preferentially restored in an actual storage space in a destination physical medium with reference to the physical media other than the physical medium that caused the fallback in the storage group.

摘要： A storage control apparatus manages a plurality of storage devices which belong to a RAID Logical Unit (RLU) such that data is made redundant between different storage devices, where RAID stands for Redundant Arrays of Independent Disks. If a first storage device fails, a rebuild controller executes a rebuild process to store the same data as recorded in the first storage device in a spare storage device. When the rebuild controller executing the rebuild process has failed in reading out data from a second storage device, a data recovery controller restarts the first storage device, and reads out data to be stored in the spare storage device from the restarted first storage device.

摘要： A control apparatus, coupled to a storage medium via communication links, controls data write operations to the storage medium. A cache memory is configured to store a temporary copy of first data written in the storage medium. A processor receives second data with which the first data in the storage medium is to be updated, and determines whether the received second data coincides with the first data, based on comparison data read out of the storage medium, when no copy of the first data is found in the cache memory. When the second data is determined to coincide with the first data, the processor determines not to write the second data into the storage medium.

摘要： A storage system including first storage devices constituting a first logical storage area, second storage devices constituting a second logical storage area; and a storage control apparatus. The storage control apparatus manages the first and second logical storage areas so that the data stored in the first and second logical storage areas have redundancy, and parity data for the data stored in the second logical storage area are stored in parity storage areas arranged in part of the second storage devices. When part of the first storage devices constituting part of the first logical storage area fail, the storage control apparatus generates part of the data stored, before the failure, in the part of the first storage devices, and stores the generated part of the data in at least part of the second parity storage areas in the second logical storage area.
