Next, a storage policy management system according to an embodiment of the present invention will be described in detail. Fig. 1 is a schematic structural diagram of a storage policy management system according to an embodiment of the present invention, where the system includes: an operation processor 11, a group manager 12, a correspondence manager 13 and an execution trigger 14,
the operation processor 11 is configured to generate corresponding storage policy group information according to the received creation information, and send the storage policy group information to the group manager 12.
The operation processor 11 may receive related information input by a user (administrator) and convert the related information into information that can be recognized by the system.
In order to ensure that the relevant information input by the user meets the form requirement, the operation processor 11 may verify the relevant information input by the user after receiving the relevant information input by the user.
The creation information may be information for establishing a storage policy group, and the creation information may carry a related storage policy or identification information corresponding to the storage policy.
Taking the identification information as an example, in a specific implementation, corresponding identification information may be set for each storage policy, and the storage policies and the corresponding identification information thereof may be stored in a form of a list in the system. The user only needs to input the identification information, and the operation processor 11 can search the corresponding storage policy according to the identification information. Wherein the identification information may be represented in the form of a number value.
One storage policy group may include a plurality of storage policies, and in the embodiment of the present invention, the storage policy group may be constructed centering on an application scenario. For example, in an application scenario, storage policy 1, storage policy 2, and storage policy 3 need to be used, and these 3 storage policies may be used as a storage policy group.
After acquiring the storage policy according to the creation information, the operation processor 11 may integrate the storage policy, and send the generated storage policy group information to the group manager 12.

The group manager 12 may maintain and maintain storage policy group information. The original volume operation processor in the storage system may be configured to establish a correspondence between the volume and the storage policy group, and the volume operation processor acquires the storage policy group information by sending a query request to the group manager 12.
The application scenario may be used as a center when the storage policy group is constructed, and correspondingly, the volume operation processor may also send a query request according to the application scenario when the storage policy group information is acquired. For example, the volume operation processor needs to configure and manage a storage policy group in a certain application scenario, and accordingly, the query request may carry flag information of the application scenario, and the group manager 12 may obtain the storage policy group information required by the volume operation processor according to the flag information, and thus send the storage policy group information to the volume operation processor.
Because a plurality of storage policy groups may exist in the system, and there may exist a relation such as reference between the storage policy groups, in the embodiment of the present invention, the management work of the storage policy groups is separated from the operation process of the storage policy groups by the division and cooperation of the operation processor 11 and the group manager 12, so that the system implementation can be simplified, and the function decoupling can be effectively implemented.

The corresponding relation manager 13 is responsible for maintaining the binding relation between the volume and the storage policy group, and because a large number of volumes and storage policy groups exist in the system, the binding relation between the volumes and the storage policy groups is maintained uniformly, so that the impact on the original system can be reduced, and the implementation complexity of the system is reduced.
The execution trigger 14 is configured to send a request to the group manager 12 to obtain storage policy group information, and receive the storage policy group information sent by the group manager 12; sending a request for acquiring volume information to the correspondence manager 13, and receiving the volume information sent by the correspondence manager 13; and sending the extracted target storage policy information and the corresponding volume information to a storage policy executor.
The storage policy group may include a plurality of storage policies, and each storage policy has different application conditions, for example, different execution times, different execution conditions, and the like. When the execution trigger 14 sends information to the existing storage policy executor in the storage system, the target storage policy information, which is storage policy information to be executed, and the corresponding volume information may be sent.
With respect to the operation steps performed by the execution trigger 14, it can be divided into a sending unit, a receiving unit and an extracting unit,
the sending unit is configured to send a request for obtaining the storage policy group information to the group manager 12.
The receiving unit is configured to receive the storage policy group information sent by the group manager 12.
And the extraction unit is used for analyzing the storage strategy group information and extracting target storage strategy information.
The sending unit is further configured to send a request for obtaining volume information to the correspondence manager 13 according to the target storage policy information.
