<p>The invention provides a storage system, comprising a processor controlling I/O processing for a plurality of storage devices; a cache memory storing write data for writing data into at least one of the plurality of storage devices and/or read data obtained by reading from at least one of the plurality of storage devices; and the plurality of storage devices having a first type storage device and a second type storage device; wherein the cache memory is logically divided into a plurality of partitions and can be performed tuning based on values of a partition size of each of the plurality of partitions. A first partition of the plurality of partitions is assigned to the first type storage device, a second partition of the plurality of partitions being assigned to the second type storage device, performance characteristics of the first type storage device is different from the performance characteristics of the second type storage device, and the partition size of the first partition is different from the partition size of the second partition.</p> |
