Abstract
A storage system includes: a controller including a plurality of processors; an interface device; and a plurality of queues associated with the interface device. The plurality of queues each store data transmitted from a processor allocated to the queue to the interface device. The plurality of queues include a private queue and a public queue. The private queue is a queue allocated with only a first processor as one of the plurality of processors, the private queue requiring no exclusion processing when data is stored, whereas the public queue is a queue allocated with two or more second processors in the plurality of processors, the public queue requiring the exclusion processing when data is stored.
