Abstract: A storage system including a first controller and a second controller, where the first controller and the second controller each coupled to at least one interface card, and each interface card includes at least one port. A bound port group is preconfigured in the storage system, and the bound port group includes ports from the first controller and the second controller. A link handover method includes when the first controller detects that a link of a first port in the bound port group is faulty, marking a status of the first port as unavailable in the bound port group, selecting a second port in an available state from the bound port group, and handing over a service carried on the link of the first port to a link of the second port.
