Description
Technical Field
The invention relates to the field of automatic testing, in particular to an automatic testing method and device for simulating the starting of a server cluster.
Background
In the using process of the server, a user often restarts the server according to the needs of the user, and when the number of the servers reaches a certain scale, the situation that the servers of a certain number cannot be started often occurs. In addition, with the large-scale construction of the data center, the situation of unexpected power failure of the data center also happens occasionally, and whether the server can be normally started after power is recovered is the key for ensuring service business under the situation of unexpected power failure.
In order to avoid the above two situations, in the process of developing a server, simulation of the above two situations needs to be considered, and since the number of machines is very limited, generally 3-5 machines, in the process of developing a server, simulation tests of the above two situations need to be performed by a method of simulating the server.
In the prior art, most server manufacturers often do not perform the test due to lack of an effective simulation method, and even if some manufacturers perform the test, a manual power-off method is often adopted. By connecting the Power supply of the batch server to a PDU (Power Distribution Unit, also called a Power Distribution socket for a cabinet), the operation of "Power off-restoration" is performed using a unified switch of the PDU.
In summary, the prior art has the following disadvantages:
(1) the material cost is higher: the batch server is adopted for simulation, so that the cost is high;
(2) the manpower cost is higher: manual power off requires a tester to operate continuously;
