摘要： A data processing system has the following construction in order to achieve high speed data processing with reduced memory capacity. There are provided a memory to store a plurality of pieces of sequentially input data to be processed, a plurality of processors to execute a series of processings, e.g., Log conversion, MTF correction, gamma correction and binarization in this order to the data to be processed stored in the memory in the order of input, and a state control portion to determine which processing is stagnant by monitoring the progress of a processing by each of said plurality of processors and prohibit a processor executing a processing succeeding to a processing determined as being stagnant from accessing the memory. Processings by the plurality of processors are executed asynchronously and the plurality of processors share the memory.

摘要： A storage sub-system employs a staging control information table by which staging of data to be read and redundant data thereof can be executed together to reduce response time in the event of a data read failure. The staging control information table also permits pre-read staging to be executed in the forward, backward or both the forward and backward directions, to reduce response time.

摘要： A storage system includes a virtual volume, a plurality of RAID groups, a pool unit for managing a plurality of first real storage areas and a controller. If a write command related to the virtual volume is issued from a higher-level device, the controller selects a prescribed second real storage area from among respective second real storage areas included in a prescribed first real storage area, and associates this prescribed second real storage area with a prescribed area inside the virtual volume corresponding to the write command, and which associates one virtual volume with one first real storage area. A migration destination determination unit selects a migration-targeted second real storage area from among the respective second real storage areas associated with the virtual volume, and selects a migration-destination first real storage area, which is to become the migration destination of data stored in the migration-targeted second real storage area.

摘要： A storage controller allocates a real storage area to a virtual volume in chunk units each comprising a plurality of pages. In a case where load bias occurs between RAID groups, data reallocation is carried out. A real storage area inside a pool is allocated to a virtual volume 5 in accordance with a write access. A RAID group 6 comprises a plurality of chunks. Each chunk 7 comprises a plurality of pages 8. The pages 8, from within the chunk 7 that has been allocated to the virtual volume 5, are used. A data migration plan is created and stored in page units based on the load of each RAID group. When a host 2 issues a command to a migration-targeted page, data is migrated while this command is being processed.
