In order to make those skilled in the art better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Referring to FIG. 1, it is an implementation flowchart of a method for querying a resource object of a storage system provided by an embodiment of the present invention. The method may include the following steps:

S110: During the normal operation of the storage system, receive a query instruction for the target resource object.

During the normal operation of the storage system, the user can send a query instruction for the target resource object to the GUI of the storage system. After receiving the query instruction for the target resource object, the operation of step S120 may be continued.

Resource objects in a storage system can be volumes, pools, and so on.

S120: Obtain the target resource class to which the target resource object belongs.

In the embodiment of the present invention, a resource class and a corresponding snapshot class can be defined for each type of resource object in advance, and the relationship between the resource class and the snapshot class can be saved in a mapping table, and the relationship between the resource class and the snapshot class can be established. Relationship mapping table.

Among them, the resource class includes the constructor, the attribute list of all attributes, the parsing method of the attribute, and so on. Taking the resource object as a volume (VDisk) as an example, the attribute list can include the volume identifier (ID), the volume name, the volume capacity, the name of the pool (MDisk) to which it belongs, and the name of the input and output group (IO Group) to which it belongs. The parsing method of the attribute, that is, the method of parsing the value of an attribute from the construction parameters.

The snapshot class includes the MCS command to query the resource object of this type, the result set returned by the query command, and the specific resource object instance set.

According to the predefined resource class and snapshot class, you can obtain the target resource class to which the target resource object belongs.

S130: Query the target snapshot class corresponding to the target resource class in the pre-established relationship mapping table between the resource class and the snapshot class.

As described above, define a resource class and a corresponding snapshot class for each type of resource object in advance, save the relationship between the resource class and the snapshot class in a mapping table, and establish the relationship mapping between the resource class and the snapshot class surface.

After obtaining the target resource class to which the target resource object belongs, you can query the target snapshot class corresponding to the target resource class in the relationship mapping table between resource classes and snapshot classes.

S140: Using the target snapshot class as the primary key, query the target snapshot instance from the cache pool.

In the embodiment of the present invention, when the storage system is started, all predefined snapshot classes in the storage system can be traversed, a snapshot instance is created for each snapshot class, and then the snapshot class is used as the primary key, and the snapshot instance is used as the value, which is stored in the In the cache pool, each resource object of the storage system is loaded through the snapshot instance, that is, the operation of loading the resource object of the snapshot instance is triggered.

Specifically, for each resource object, the MCS command for querying the resource object can be obtained, the execution request for the MCS command can be sent to the multi-controller system MCS, and the response result returned by the multi-controller system can be received, as shown in FIG. 2 . Commands to query volumes return results. Save the response results in the result set of the cache pool by row, traverse the data rows in the result set according to the row index, call the constructor of the resource object, construct a resource object instance with the snapshot instance and row index as parameters, and query the resource object The identifier, that is, the ID, takes the identifier of the resource object as the primary key and the resource object instance as the value, and is stored in the resource collection of the snapshot instance.

That is, each time the storage system is started, the cache pool pre-stores the snapshot class related information corresponding to each resource object. The snapshot class related information uses the snapshot class as the primary key and the snapshot instance as the value. After querying to obtain the target snapshot class corresponding to the target resource class, you can use the target snapshot class as the primary key to query the target snapshot instance from the cache pool.

S150: Using the identifier of the target resource object as the primary key, query the target resource object instance from the resource set of the target snapshot instance.

As described above, each time the storage system is started, the resource collection of the snapshot instance stores relevant information with the identifier of the resource object as the primary key and the resource object instance as the value. Therefore, with the identifier of the target resource object as the primary key, the target resource object instance can be queried from the resource set of the target snapshot instance.

S160: Further query the required attributes of the target resource object instance.

In a specific implementation of the present invention, the required attributes of the target resource object instance can be queried through the following steps:

Step 1: Take out the target snapshot instance and index from the constructor of the target resource object;

Step 2: Get the result set from the target snapshot instance;

Step 3: Based on the first row of the result set, obtain the attribute header of the resource list;

Step 4: Obtain the index+1 row from the volume list according to the index index of the resource, and obtain the attribute value list of the specific resource;

Step 5: Traverse the header of the attribute value list, take values from the attribute value list in turn, save each attribute and attribute value in the key-value pair data type, and obtain the attribute and attribute-value key-value pair of a specific resource;

Step 6: According to the attribute name of the attribute to be queried, find the corresponding string value from the attribute and attribute value key-value pair;

Step 7: Decode the string value into the data type corresponding to the property to be queried.

For the convenience of description, the above steps are combined for description.

The target snapshot instance and index can be fetched from the constructor of the target resource object, and the result set can be fetched from the target snapshot instance. Get line 1 from the result set, apply the command delimiter ("," by default) to split the string into a list of substrings, and get the attribute header of the resource list.

Get line index+1 from the volume list according to the resource's index index, apply the command separator ("," by default) to split the string into a list of substrings, and get a list of property values for a specific resource.

Traverse the header of the attribute value list, get values from the attribute value list in turn, save each attribute and attribute value in the key-value pair data type, and obtain the attribute and attribute-value key-value pair of a specific resource.

According to the attribute name you want to query, find the corresponding string value from the attribute and attribute value key-value pair. Decodes the string value to the data type corresponding to the property.

In the embodiment of the present invention, for information that changes infrequently, such as resource objects, it is preloaded into the system memory, which can reduce the command interaction cost between the GUI and the storage MCS, improve the loading efficiency of the front-end page, and improve the user experience. experience.
