Abstract: A method is applied to a system including a host cluster and at least one pair of storage arrays. The host cluster includes a quorum host, the quorum host includes a quorum unit, and the quorum host is an application host having a quorum function. A pair of storage arrays includes a first storage array and a second storage array. The quorum host receives a quorum request, temporarily stops delivering a service to the first storage array and the second storage array, determines, from the first storage array and the second storage array, which is a quorum winning storage array and which is a quorum losing storage array according to logic judgment, stops the service with the quorum losing storage array, sends quorum winning information to the quorum winning storage array, and resumes the delivered service between the host cluster and the quorum winning storage array.

Abstract: A data replication method and a storage system are provided. The method is applied to a storage system including a first storage device and a second storage device. According to the method, after determining replication information, a first storage system determines a first replication sub-information and a second replication sub-information according to the replication information, where the replication information is used to indicate data that needs to be replicated by the first storage system to a second storage system in a current replication task. Then, the first storage device replicates data to the second storage system according to the second replication sub-information, and the second storage device replicates data to the second storage system according to the second replication sub-information.
