Abstract
According to embodiments of the present invention, in a storage system, a switch receives an operation request, where the operation request carries request identification; the switch queries, according to the request identification, a flow table of the switch to obtain a flow table entry matching the operation request; and the switch forwards the operation request to a target storage device among storage devices according to a forwarding rule of the matching flow table entry. By using a characteristic of a SDN, the operation request is processed according to the forwarding rule of the flow table entry of the switch, thereby implementing load balancing of the storage devices and reducing information interaction between the storage devices.
