Title: STORAGE SYSTEM AND STORAGE CONTROL METHOD
Abstract:
In the present invention, a storage system is configured so that, upon executing balance processing for moving data among a plurality of memory device groups constituted by a plurality of memory devices, it is determined whether it is necessary to execute balance processing for satisfying a first avoidance request for avoiding a problem that occurs only in any of the memory devices, and such determination is made on the basis of a second avoidance request satisfied by second balance processing that has been executed before first balance processing for satisfying the first avoidance request. If the results of such determination are affirmative, the first balance processing is executed.
