The controllers each have the physical storage device being different from that of each other and the host connected thereto being different from that of each other, and are each able to access the physical storage device and the host that are not connected thereto, through another controller. Any one of the controllers has an ownership to process an access request concerning the logical storage device. At least one controller determines that the ownership is caused to be moved among the controllers, based on an index of accesses to the physical storage device that includes the storage area to be assigned to the logical storage device and an index of accesses to the host that accesses the logical storage device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Storage system","description":"A storage system includes controllers, physical storage devices, and logical storage devices to which storage areas are assigned from the physical storage devices.
