The at least one second server may be a second server in one of a plurality of nodes in the server network, or may be a second server in a different node of the plurality of nodes in the server network.
The user test request includes IP address information of at least one second server. For example, the IP address information may be an IP address field corresponding to at least one second server located in the same node. Alternatively, the IP address information may include IP addresses respectively corresponding to the second servers.
In this embodiment, the user may send the test request to the scheduling server when a plurality of second servers are newly deployed in the server network (RDMA network cards are installed on the second servers). Or a test request initiated at a verification of some new function. It may also be a test request initiated based on verification of an exception.
After receiving the test request, the dispatch server may generate a test instruction according to the test request.
The test instructions may include a plurality of test commands. The test commands are used to generate test stresses. The test command may include, for example, access to data, etc. In some application scenarios, the test command may be used to generate a plurality of test stresses every preset time period. In other application scenarios, the test command is used to generate a predetermined amount of test stress.
The test stress may be, for example, instructing a second server to send data read/write requests to other second servers.
The dispatch server may encapsulate the plurality of test commands into test instructions.
In some optional implementation manners, the user test request includes an exception verification request, and the test instruction is generated according to the received user information processing request, including the following steps:
firstly, historical operating data of a second server is obtained and input into a pre-trained scene model.
The obtaining of the historical operating data of the second server may include obtaining historical operating data of a plurality of second servers at and before the occurrence of the abnormality.
The scene model can be an artificial neural network model, a deep learning model and the like.
For the pre-trained content of the scene model, reference may be made to the above related parts, which are not described herein again.
Secondly, determining the test instruction based on the output obtained by operating the scene model; the test instruction comprises a plurality of operation parameters corresponding to the historical operation of the second server.
The historical operating data comprises historical abnormal operating data; and the plurality of operating parameters comprise a plurality of corresponding operating parameters before and after the second server has the historical abnormality.

The scheduling server can generate general test instructions corresponding to different types of RDMA network cards. For the universal test instruction, after the second server receives the universal test instruction, the second server may parse the test instruction and execute the test command in the test instruction by the RDMA network card.
In some optional implementation manners, the generating a test instruction according to the received user test request includes: and generating a test instruction matched with the target type based on the pre-acquired target type of the RDMA network card in the second server.
In these application scenarios, if the scheduling server obtains the RDMA network card type of the second server according to the communication information between the scheduling server and the second server in advance, a test instruction matching the RDMA network card type may be generated according to the known RDMA network card type of the second server. In this way, the scheduling server can generate respective corresponding test instructions for different RDMA network card types, and steps of converting the general test instructions into the test instructions executable by the RDMA network card by the second server can be reduced.
Step 202, sending the test instruction to at least one second server, so that the at least one second server runs the test instruction, wherein when the second server runs the test instruction, an RDMA network card is used for realizing reading/writing of transmission data between different second servers.
In some application scenarios, sending the test instructions to at least one second server includes sending the test instructions to the second server based on a TCP/IP protocol or an RDMA protocol.
That is, if the RDMA gateway is not installed in the scheduling server, the scheduling server may send the test instruction to each second server according to the TCP/IP protocol.
In some application scenarios, if the RDMA network card is installed in the scheduling server, the scheduling server may install an RDMA gateway protocol to send the test instruction to each second server.
Optionally, the historical operating data comprises historical abnormal operating data; and the plurality of operating parameters comprise a plurality of corresponding operating parameters before and after the second server has the historical abnormality.
The second server may execute the test command in the test instruction. For example, data read/write operations are performed according to the test command. For example, according to the test command, a plurality of data read/write requests are sent to other second servers indicated by the test command, so that the other second servers execute a plurality of read/write operations.

When executing the test instruction, the second server may send the test data generated when the local terminal executes the test instruction to the scheduling server.
In some application scenarios, the second server may send a data read/write request to another second server, and the another second server may feed back data information obtained by performing an operation corresponding to the data read/write request to the second server. The second server may transmit the data information to the dispatch server as test data of the other second server according to the test command.
The dispatching server can analyze and process the test data to obtain a displayable test result. The displayable test results may include graphical test results. The graphical test results may include graphs, histograms, scatter plots, pie charts, and the like.
And step 204, displaying the test result.

Referring to fig. 3, a flow chart of one embodiment of a testing method of a server cluster provided by the present disclosure is shown. The test method of the server cluster is applied to the second server shown in fig. 1. As shown in fig. 3, the method for testing a server cluster includes the following steps 301 to 304.
Step 301, receiving a test instruction sent by the dispatch server, where the test instruction is generated by the dispatch server according to the received user test request.

After receiving the test instruction, the second server may execute the test instruction, for example, parse the test instruction, and parse the test command and the RDMA network card parameter from the test instruction. The second server may execute the test command. The test instructions may direct the at least one transfer data to be sent to the target second server using the RDMA network card. The number of the target second servers may be one or more.
In some application scenarios, the test instruction may further include a multi-dimensional parameter, such as an RDMA gateway parameter, which includes but is not limited to: the size of the transmitted data packet, the transmission frequency of the data packet, the routing of the transmission and the like, and the operation type parameters corresponding to the transmission data.
In these application scenarios, when the second server executes the test instruction, the second server sets a corresponding environment according to the parameters indicated in the test instruction. For example, according to the RDMA gateway parameters in the test command, the size of the sending data packet, the transmission frequency of the data packet, the transmission route of the data packet, etc. are set. And for example, the target second server is instructed in the test instruction to execute the operation indicated by the operation type parameter. Alternatively, an operation indicated by the operation type in the test instruction is executed in accordance with the test instruction.
In these application scenarios, the RDMA gateway parameter and/or the operation type parameter may be an output result obtained by using the historical operation data of the at least one second server as an input of a pre-trained scenario model. The scene model may run on a scheduling server. And the dispatching server generates a test instruction according to the output result. The output result comprises the RDMA gateway parameter, the operation type parameter and the like.
In these application scenarios, the at least one second server may reproduce the history scenario through the test instruction. If the test command is generated according to historical abnormal data, the reproduced historical scene can facilitate a user to analyze the historical abnormal data.
The sending of the at least one transmission data to the target second server using the RDMA network card includes sending the at least one transmission data to the target second server within a preset time period.
The first target RDMA network card may be installed in the target second server. The RDMA network card can directly store the transmission data into the first preset storage area. The first preset storage area may be an area which is determined in advance and can be used for directly reading/storing data by the RDMA network card. In some application scenarios, the second server of the data sender sends a test request (data storage request) to the second server of the data receiver, where the test request may include data to be stored, information of the first preset storage area, and the like. The second server of the data sending party can use the RDMA network card installed thereon to send the test request to the RDMA network card of the second server of the data receiving party. The RDMA network card of the second server of the receiving party can store the data to be stored into the first preset storage area indicated by the test request according to the test request.
In addition, the target second server may be a second server of the data sender. The second server executing the test method may send, to the target second server, a test request instructing the target second server to send transmission data to the second server according to the test instruction. The target server may send transmission data to the second server according to the test request.
