Specifically, the server information may be acquired by, for example, sending a corresponding command to the server through SSH, creating a server class, creating a server object instance in the server class, and adding all server object instances to the server class; acquiring all FC port information of all servers, creating FC port classes of the servers, creating FC port object instances of the servers under the FC port classes of the servers, respectively adding all the FC port object instances to the FC port classes of the corresponding servers, and adding the FC port object instances to the corresponding server object instances.
Acquiring all storage clusters connected with a server, for example, the storage cluster information connected with the server can be acquired by sending corresponding commands to the storage clusters through SSH, creating a cluster management class, creating cluster object instances under the cluster management class, and adding all the cluster object instances to the cluster management class; the storage device node in each storage cluster is acquired, for example, information of the storage device node can be acquired by sending a corresponding command to the storage cluster through SSH, a storage device node management class is created, a storage device node object instance is created in the storage device node class, all the storage device node object instances are added to the corresponding storage device node class, and the storage device node object instance is added to the corresponding cluster object instance.

When the topological graph is generated, firstly, the size of a server and drawing coordinates of the server are determined, the size of the server is required to be moderate, the server is reasonably distributed on a canvas, for example, the size of the server is generated to be 50 x 200 pixels, an FC port of the server is generated to be 15 x 50 pixels, the position of the server is symmetrical about the central line of the canvas, the position of the FC port is symmetrical about the central line of the server, then, a corresponding drawing library, for example, a turtle drawing library, is called, and corresponding information is input, so that the graph of the server can be generated.
Then, an FC port map of the storage device cluster, the storage device nodes, and the storage device nodes is generated, for example, the storage device cluster 1 is 100 × 100 pixels, the storage device cluster 2 is 100 × 300 pixels, each storage device node is 50 × 80 pixels, the FC ports of the storage device nodes are 15 × 50 pixels, 4 storage device nodes are arranged at equal intervals, and are symmetrical about two of the canvas center lines, and the FC port positions are symmetrical about the storage device node center lines, then a corresponding drawing library, for example, a virtual drawing library, is called, and corresponding information is input, and a server map can be generated.
And finally, inputting corresponding information in a drawing library, and connecting the FC port of the server with the connection relation with the FC port of the storage device node, so that a complete topological graph is generated.
Based on the return information obtained by sending the query information to the server and the storage device through SSH, the object instance is constructed and the drawing coordinates and the size are calculated based on the obtained return information, so that the automatic generation of the topological graph is realized, the method is simple and convenient, and the working efficiency is improved.

updating the FC port object instance in the server object instance and the FC port object instance in the node management module object instance based on the connection relationship, comprising:
and updating the default drawing color between the FC port object instances with the connection relation.
Specifically, for example, if the default drawing color is gray, the FC port that acquires the server may change the color to another color, such as red, green, black, yellow, purple, and the like, after having a connection relationship with the FC port of the corresponding storage device, because in the process of generating the topology map in this example, the FC port that also acquires the server may also be connected with FC ports of other devices, such as a switch, and the FC port of the switch that connects the FC port of the server with the port has the default color when generating the topology map, but what the tester needs to see is the connection between the FC port of the server and the FC port of the corresponding storage device, the color is distinguished to be the default color, and the topology map that the tester sees can see is clearer.
