Abstract:
An object of the present invention is to provide a storage system which is shared by a plurality of application programs, wherein optimum performance tuning for a cache memory can be performed for each of the individual application programs. The storage system of the present invention comprises a storage device which provides a plurality of logical volumes which can be accessed from a plurality of application programs, a controller for controlling input and output of data to and from the logical volumes in response to input/output requests from the plurality of application programs, and a cache memory for temporarily storing data input to and output from the logical volume, wherein the cache memory is logically divided into a plurality of partitions which are exclusively assigned to the plurality of logical volumes respectively.
