If not, the inspection module prompts that the serial connection to the small computer system interface is abnormal. A serial connection small computer system interface test method, the method includes the following steps: generating a virtual memory in the serial connection small computer system interface to be tested, the virtual memory is used for storing data packets; acquiring the string Linking the properties of the small computer system interface; sending a data packet to the loopback software dog connected to the serial connection small computer system interface through the serial connection of the small computer system interface, the data package includes test data, The serial connection to the small computer system interface attribute and transmission protocol 'receives the data packet sent back by the loopback software dog through the receiving pin of the serial connection small computer system interface; and stores the received data packet to In the generated virtual memory; check whether the information contained in the received data package 201035749 is the same as the information contained in the sent physical package; if the same, the prompt is to (4) connect the small "brain pure interface" Normal; and if not the same, it is suggested that the serial connection to the small system interface is not normal. Compared with the conventional technology, the household string Connect the small computer system interface test test system and method, use the carcass to replace the hardware device, reduce the cost, and effectively test the SAS interface. [Embodiment] Modify the font of the "test system" in Figure 2; modify Figure 4 The "埠" is the "interface". η is an operating environment diagram of a preferred embodiment of the serial connection small computer system interface test system of the present invention, as shown in Fig. 2. The test system 100 operates on the SAS controller 1, The SAS controller i includes a plurality of SAS interfaces 2, and the SAS controller 1 stores attributes of the SAS interface 2. Each SAS interface 2 includes a transmit pin 2A and a receive pin 2〇1, The transmit pin 200 and the receive pin 2〇1 are connected to a loopback dongle 3. The loopback software dog 3 is configured to receive the transmit pin 2 connected to the loopback software dog 3.资料 sent the data packet, and send the data packet back to the receiving pin 2〇1 connected to the loopback software dog 3. As shown in FIG. 3, it is a functional module of the test system 1 in the figure of the present invention. The module is a software program with specific functions. The software can be stored in a private storage device or other storage device, and can be executed by a computer or other computing device including a processor, thereby completing a series of processes for serially connecting small computer system interface tests. The method includes: a generating group 10, an obtaining module 12, a transmitting module 14, a receiving module W, a storage module 18, and an inspection module 2. The 201035749 is used for the SAS required for testing The interface 2 generates a virtual money body for storing the data package. The human acquisition module 12 is configured to acquire the attribute of the sas interface 2, and the upper attribute includes the identification word of the s As interface 2 (10) ― "(10), ID) 模组, module 14 is used to transmit the packet to the loopback software dog 3 through the transmit pin 2 of the SAS interface 2. The data package includes test data, information about the attributes and transmission protocols of the SAS interface 2. The receiving module 16 is configured to receive the data packet sent back from 3 through the receiving pin 2〇1 of the SAS interface 2. The storage module 18 is configured to store the received data package into the generated virtual memory. The sub-test module 2 is used to check whether the received data packet contains the same information as the information contained in the sent data packet. If it is the same, the physical package is the sent data packet, and the inspection module 20 prompts the ❹ SAS ” face 2 to be normal. If not, the inspection module 2 〇 indicates that the sas interface 2 is abnormal. As shown in FIG. 4, it is a flowchart of a method for a preferred embodiment of the serial connection small computer system interface testing method of the present invention. Step S40, the generating module 10 generates a virtual memory in the SAS interface 2 to be tested. The S12 is configured to obtain the attribute of the SAS interface 2, and the attribute of the SAS interface 2 includes the ID of the SAS interface 2. In step S42, the sending module 14 transmits the SAS interface 2 Send the 201035749 pin 200 to send the data packet to the loopback software dog 3. The data packet includes test data, attributes of the SAS interface 2, and transmission protocols. Step S43, the receiving module 16 receives the content through the SAS interface 2. The pin 201 receives the data packet sent back from the loopback software dog 3. In step S44, the storage module 18 stores the received data packet into the generated virtual memory. In step S45, the check module 20 is used for checking. The received data Whether the included information is the same as the information contained in the sent data packet. If yes, the process goes to step S46. If not, the process goes to step S47. In step S46, the checking module 20 prompts the SAS interface 2 to be normal.
