Description

Server test system and method

The present invention relates to a server test system and method.

In large data processing centers, a single cabinet can usually accommodate multiple servers, and each server requires a stress test. Referring to FIG. 1 , in the test, a test host 10 needs to be connected to two switches at the same time, and a LAN (Local Area Network) of each server 30 is connected to a port corresponding to a switch 200, and each server is connected. The BMC (Baseboard Management Controller) of 30 is connected to the port corresponding to the other switch 201. When performing the stress test, the test host 10 controls all the servers 30 to perform the booting operation through the switch 201. Thereafter, the test host 10 broadcasts the servers 30 through the switch 200, thereby connecting to the switch 200. Each server 30 performs a stress test. However, during the above stress test, the test data needs to be transmitted to all the servers 30 connected to the switch 200 in the form of broadcast data, so that a broadcast storm may occur, which may cause network congestion and affect the test result.

In view of the above, it is necessary to provide a server test system and method that can avoid broadcast storms.

A server test system is applied to a switch, and each of the first port and the second port of each server is connected to a port of the switch. The server test system includes:

a grouping unit for grouping the ports connected to the first port of each server on the switch;

a network segment allocation unit, configured to allocate IP addresses having different network segments to 埠 in different packets in the switch, so that different servers have IP addresses of different network segments;

a pressure test unit for outputting the pressure test signal to the first port of all servers in the same network segment to complete the stress test of the server in the network segment; and

A switch test unit is configured to output a switch test signal to a second port of a server to perform a switch operation on the server.

A server test method includes the following steps:

Connect the network of each server to the switch of a switch;

Grouping the complex 埠 of the switch;

Allocating different groups of IP addresses with different network segments;

Outputting a pressure test signal to the network of servers in the same network segment; and

The output switch test signal is sent to the network of a server.

The above server test system and method group different network ports of different servers, and assign IP addresses with different network segments to servers of different groups, so that the broadcast storm can be effectively avoided during stress test.

Referring to Figures 2 and 3, the server test system 70 of the present invention is used to stress test the complex server 60, which is applied to a switch 50 in which the network of each server 60 is One of the switches 50 is connected. The network port of each server 60 includes a LAN port 600 and a BMC port 602. The preferred embodiment of the server test system 70 includes a pressure test unit 700, a switch test unit 702, a grouping unit 704, and a network segment allocating unit 706.

The unit grouping unit 704 is configured to group the ports of the switch 50, such as dividing the port of the switch 50 into a first packet, a second packet, and the like. The number of defects contained in each of the groups may be unequal or equal. In this embodiment, the types of the network ports of the servers 60 connected to each group are the same, that is, the ports in the same group are all connected to the LAN port 600 of the server 60 or all connected to the server 60. BMC埠602.

The network segment allocating unit 706 is configured to allocate IP addresses having the same network segment to each of the packets in each packet, and allocate IP addresses with different network segments between different packets, so that each packet corresponds to the server. The ports connected to the LAN 埠 600 of 60 can form a virtual area network.

The switch test unit 702 is configured to perform a switch operation on the server 60. Specifically, when the control server 60 is required to perform the power on/off operation, the switch test unit 702 outputs the switch signal to the BMC 602 of the corresponding server 60. When the corresponding server 60 receives the power on/off signal, it performs a considerable power on/off operation. In other embodiments, since the control server 60 performs the on/off operation without generating a broadcast storm, the B of the BMC 602 for connecting to the server 60 in the switch 50 may not perform packet processing.

The pressure testing unit 700 is configured to perform a stress test on the plurality of servers 60 in the power-on state. Specifically, when it is required to test the server 60 in a certain network segment, the switch test unit 702 outputs a switch signal to the BMC 602 of all the servers 60 in the network segment, and then the pressure test unit 700 The LAN 埠 600 of the server 60 located in the network segment is network broadcasted. That is, after receiving the pressure test command outputted by the test host 40, the pressure test unit 700 performs network broadcast according to the IP address in the corresponding network segment according to the pressure test command, so as to stress all the servers 60 in the corresponding network segment. test. In the pressure test of the server 60, the network test of the server 60 in each network segment can complete the stress test of the server 60 connected to the network segment corresponding to the network segment, thereby avoiding the At the same time, all servers 60 perform network broadcasts and may bring broadcast storms.

Referring to FIG. 4, a preferred embodiment of the server testing method of the present invention includes the following steps:

In step S1, the network connected to each server 60 is connected to the switch 50. The network includes the LAN port 600 and the BMC port 602 of the server 60.

In step S2, the 埠 of the switch 50 is grouped.

In step S3, the 埠 of different packets are allocated with IP addresses of different network segments.

In step S4, the switch test signal is transmitted to the BMC of the server 60 in a network segment.

In step S5, the pressure test signal is transmitted to the LAN port of all the servers 60 in the network segment to complete the stress test of all the servers 60 in the network segment.

The server test system and method described above group the ports of the switch 50, and assign IP addresses of different network segments to different groups of packets, so that the broadcast storm can be effectively avoided during the stress test.

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and those skilled in the art will be able to make equivalent modifications or variations in accordance with the spirit of the present invention.
