STORAGE APPARATUS AND CONFIGURATION MANAGEMENT REQUEST PROCESSING METHOD FOR STORAGE APPARATUS

A storage apparatus 10 includes: a plurality of controllers, each of which has a plurality of processors for processing requests; a storage device coupled to the controller: an integration unit that integrally controls the plurality of controllers; and a shared memory that can be accessed from each processor for the plurality of controllers and stores configuration information of the storage apparatus including load information of each processor. The integration unit: calculates estimated processing time of a configuration management request, which has been accepted from a management apparatus, from a request type and a target resource type of the configuration management request; and distributes the configuration management request to a plurality of distribution requests on the basis of the load information of each processor acquired from the shared memory and the estimated processing time, determines a distribution destination processor for processing each of the plurality of distribution requests.
