Configuration method and system of hierarchical storage of storage gateway

The invention discloses a configuration method and system of the hierarchical storage of a storage gateway and relates to the technical field of the storage. The method comprises the steps that: a virtualization gateway virtualizes a configuration port, and multiple virtual configuration ports are virtualized on the configuration port; the storage gateway obtains a LUN with the configuration of media attributes from multiple virtual hosts which are set by a back-end array and are in one-to-one correspondence with multiple virtual configuration port; the storage gateway carries out hierarchicalstorage and creation on a storage medium connected to the storage gateway according to the obtained LUN with the configuration of the media attributes so as to classify different types of storage media into corresponding types of storage media layers. According to the method and the system, the attributes of the identified LUN on a gateway backend storage can be quickly set on a gateway product,and the complexity of sett
