Problems solved by technology

[0003] Currently, most test team members perform SAS expander communication tests manually. During this period, they need to manually connect external storage media and perform manual operation detection, which consumes a lot of test time and manpower. In addition, because the storage is an industrial network product rather than general Consumer electronic products are popular in the market, so there are few SAS expander communication test automation software tools for general-purpose or dedicated memory in the market, and most of the current SAS expander communication tests need to be connected to another SAS device or external storage device (such as: hard disk) etc.), so the investment in test equipment resources is also large
[0004] Manual testing of storage SAS expanders takes a lot of time and manpower, and requires a lot of testing equipment resources, resulting in high project development costs and low efficiency. In addition, manpower to judge test results sometimes produces human errors.

Embodiment 1

[0064] like figure 1 As shown, this embodiment provides a SAS expander loopback test method, including the following steps:

[0065] S1: Connect the test control end to the storage to be tested, and deploy the SAS expander loopback test environment on the test control end.

[0066] First, install the Windows operating system and the Tera Term open source tool on the test control terminal, and connect the serial cable directly to the serial port of the memory to be tested; then, connect the SAS Lookback connector to the program interface of the SAS expander.

[0067] S2: Install the preset test script on the test control terminal.

[0068] Specifically, the preset test script is installed in the Tera Term directory of the Windows operating system in the test control terminal, so as to execute the preset test script through the graphical interface of Tera Term.

[0069] S3: Execute the preset script start command to start the preset test script and set the serial port.

[007...

Embodiment 2

[0088] Based on Example 1, as figure 2 As shown, the present invention also discloses a SAS expander loopback test system, comprising: a deployment unit 1 , a script installation unit 2 , a test start unit 3 , a test execution unit 4 and a test result output unit 5 .

[0089] The deployment unit 1 is used to connect the test control terminal with the storage to be tested, and deploy the SAS expander loopback test environment on the test control terminal.

[0090] The deployment unit 1 is specifically used to: install the Windows operating system and the Tera Term open source tool on the test control terminal, and connect it directly to the serial port of the storage under test with a serial cable; connect the SAS Lookback connector to the program interface of the SAS expander.

[0091] The script installation unit 2 is used for installing the preset test script on the test control terminal.

[0092] The test start unit 3 is used to execute the preset script start command to ...

Embodiment 3

[0097] The present embodiment discloses a SAS expander loopback test device, including a processor and a memory; wherein, the processor implements the following steps when executing the SAS expander loopback test program stored in the memory:

[0098]1. Connect the test control end to the storage to be tested, and deploy the SAS expander loopback test environment on the test control end.

[0099] 2. Install the preset test script on the test console.

[0100] 3. Execute the preset script start command to start the preset test script and set the serial port.

[0101] 4. Invoke built-in modules and SAS expander driver commands in turn to test.

[0102] 5. During the test process, the test data is continuously transmitted through the SAS expander, and the test results and process data are displayed on the screen of the test control terminal.

[0103] Further, the SAS expander loopback test device in this embodiment may further include:

[0104] The input interface is used to o...

Abstract

The invention provides an SAS expander loopback test method and system, and the method comprises the steps: connecting a test control end with a to-be-tested memory, and carrying out the loopback test environment deployment of an SAS expander at the test control end; installing a preset test script at a test control end; executing a preset script starting command to start a preset test script and setting a serial port; driving commands of the built-in module and the SAS expander are called in sequence for testing; and continuously transmitting test data through the SAS expander in a test process, and displaying a test result and process data on a screen of a test control end. According to the invention, the automatic test of the SAS expander can be realized, the working time of a tester is greatly shortened, the test efficiency is improved, and the cost expenditure of test equipment is reduced.

Description

technical field [0001] The invention relates to the technical field of memory testing, and more particularly to a method and system for loopback testing of a SAS expander. Background technique [0002] With the development of the memory industry, memory has become an important network industrial infrastructure. The main function of the memory is to store a large amount of data information and documents. Therefore, in addition to many internal storage media (such as hard disks, etc.), it also provides various specifications of expanders (such as SAS, SCS, etc.) to connect external storage devices to increase storage capacity. At present, the SAS expander is one of the mainstream storage expanders in the memory, so all kinds of memory products need to be tested for the communication of the SAS expander in the process of R&D and manufacturing. [0003] Now, most of the test team members perform the SAS expander communication test manually, during which they need to manually co...
