Abstract
Efficient communication between storage controllers can be performed. A storage system includes one or more backend switches that connect a first processor, a second processor, and one or more storage devices to each other. Each backend switch identifies a destination of a frame by referring to the frame received from the first processor. In a case where the destination of the frame is the second processor, each backend switch translates a first address, included in the frame, for specifying a location on the second memory in an address space of the first processor, into a second address for specifying the location on the second memory in an address space of the second processor, and transfers the frame including the second address to the second storage controller.
