DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0023] To facilitate understanding of this embodiment, the embodiments of the present application are described in detail below.

[0024] The present application embodiment provides a RAID array testing method, such as Figure 1 As shown, Figure 1 A flowchart of a RAID array testing method provided in an embodiment of the present application. The method comprises the following steps: S101, the server pre-configures M test data corresponding to M RAID arrays to be tested.

[0025] Specifically, the above-mentioned RAID array to be tested is created by the server after the RAID card to be tested is inserted into the test disk. The server can create multiple RAID arrays to be tested, and M RAID arrays to be tested can be tested together. Before the test, the staff will input the test data corresponding to the RAID array to be tested into the server through the visual interface. The types of RAID arrays to be tested include RAID0, RAID1, RAID5 and RAID6. Each type of RAID array to be tested has corresponding test data. Each type of test data corresponds to a different test scenario (use case).

[0026] S102: The server divides the test data corresponding to each RAID array to be tested into N test data blocks.

[0027] Specifically, the server needs to process the test data in blocks, so that in the subsequent test process, the RAID array to be tested can read each data block.

[0028] S103, in the first test mode, the server writes N test data blocks of each test data into N storage blocks of the test disk corresponding to each RAID array to be tested.

[0029] Specifically, each test disk is composed of N storage blocks. In the first test mode, the server writes a test data block in each (N) storage block, so that the RAID array to be tested can read the test data block in each storage block of the test disk.

[0030] Such an arrangement can make the entire RAID to be tested be tested, thus achieving a comprehensive test and improving the accuracy and reliability of the test results.

[0031] S104: The server instructs each RAID array to be tested to read N test data blocks from N storage blocks of a test disk corresponding to each RAID array to be tested.

[0032] Specifically, in the first test mode, the RAID array to be tested needs to read from the first storage block to the last storage block through the pointer to implement a read test of the test data block in each storage block. The pointer is used to indicate the location (address) of the storage block currently read by the RAID array to be tested.

[0033] S105, the server determines whether the nth test data block read by the mth RAID array to be tested is the same as the nth data block written by the server, if so, execute S107, if not, execute S106.

[0034] Specifically, in the first test mode, the server may compare the test data block read from the RAID array to be tested with the test data block pre-written into the storage block to determine whether the function of the RAID array to be tested is normal.

[0035] With this setting, the test principle is simple and easy to operate, and the test results are obvious, making the test process more convenient.

[0036] S106: The server determines that the mth RAID array to be tested is abnormal.

[0037] Specifically, if the reading result is that the nth test data block read by the mth RAID array to be tested is different from the nth data block written by the server, it means that the mth RAID array to be tested is abnormal.

[0038] S107: The server determines that the mth RAID array to be tested is normal.

[0039] Specifically, if the reading result is that the nth test data block read by the mth RAID array to be tested is the same as the nth data block written by the server, it means that the mth RAID array to be tested is normal.

[0040] The embodiment of the present application provides a RAID array testing method, in which the server instructs each RAID array to be tested to read N test data blocks in the N storage blocks of the test disk corresponding to each RAID array to be tested; if the nth test data block read by the mth RAID array to be tested is different from the nth data block written by the server, the mth RAID array to be tested is abnormal; if the nth test data block read by the mth RAID array to be tested is the same as the nth data block written by the server, the mth RAID array to be tested is normal. In this method, multiple RAID arrays to be tested can be tested at the same time. Compared with the prior art, in which the RAID arrays are tested one by one, this method can pre-configure the test data (use case) in the server, and divide the test data into multiple test data blocks and write them into each storage block. During the test process, each RAID array to be tested can simultaneously read the test data blocks in each storage block, thereby completing the parallel test of multiple RAID arrays to be tested. The principle of this method is simple and easy to operate, and the reading results of the RAID array to be tested are obvious and easy to judge, which greatly shortens the test time of the RAID array to be tested, improves the efficiency of the test of the RAID array to be tested, and reduces the burden of manpower testing. In addition, the entire process of this method does not require human intervention, ensuring the accuracy and reliability of the test results.

[0041] The second test mode is introduced below. In the second test mode, the server writes J test data blocks out of N test data blocks of each test data into any J storage blocks out of N storage blocks of the test disk corresponding to each RAID array to be tested; instructs each RAID array to be tested to read J test data blocks out of J storage blocks of the test disk corresponding to each RAID array to be tested; if the read result received by the server is that the j-th test data block read by the m-th RAID array to be tested is different from the j-th data block written by the server, then it is determined that the m-th RAID array to be tested is abnormal; if the read result received by the server is that the j-th test data block read by the m-th RAID array to be tested is the same as the j-th data block written by the server, then it is determined that the m-th RAID array to be tested is normal.

[0042] Specifically, in the second test mode, the memory of the test disk is large and has more storage blocks, so the server randomly selects J storage blocks from the N storage blocks and writes the J test data blocks into the selected J storage blocks. The server compares the test data blocks read from the RAID array to be tested with the test data blocks pre-written into the storage blocks to determine whether the function of the RAID array to be tested is normal. If it is determined that the mth RAID array to be tested is abnormal, the server will record the position where the mth RAID array to be tested reads abnormally and generate an error report. Among them, the position where the mth RAID array to be tested reads abnormally is determined by the pointer used when reading the test data block. In addition, after any of the above test modes (the first test mode and the second test mode) ends, the server will automatically start the test of the next type of RAID array to be tested.

[0043] With such a setting, the RAID array to be tested can read the test data block in the randomly selected storage block. In the above-mentioned second test mode, the RAID array to be tested needs to use a pointer to the data block in the randomly selected storage block to realize a fast test of the RAID array to be tested. Among them, the pointer is used to indicate the location (address) of the storage block read by the current RAID array to be tested. The test speed of this method is faster, the test efficiency is improved, and the test time is saved. The error report includes the location of the abnormal reading of the mth RAID array to be tested, so that subsequent staff can correct the abnormal mth RAID array to be tested according to the error report.

[0044] In one embodiment, M RAID arrays to be tested pre-generate M virtual test disk numbers corresponding to the M RAID arrays to be tested, and M virtual starting storage addresses corresponding to the M virtual test disk numbers; the server obtains the M test disk numbers corresponding to the M RAID arrays to be tested and the M starting storage addresses corresponding to the M test disk numbers; if the M test disk numbers are the same as the M virtual test disk numbers and the M virtual starting storage addresses are the same as the M starting storage addresses, then start testing the M RAID arrays to be tested; if the m-th test disk number is not the same as the m-th virtual test disk number and / or the m-th virtual starting storage address is not the same as the m-th starting storage address, then the server stops testing the m-th RAID array to be tested.

[0045] Specifically, the above-mentioned M test disk numbers and the M starting storage addresses corresponding to the M test disk numbers are the standards for the server to determine whether to start testing the M RAID arrays to be tested. The server will start the test program only when the M virtual test disk numbers corresponding to the M RAID arrays to be tested correspond to the M test disk numbers one by one, and the M virtual starting storage addresses corresponding to the M virtual test disk numbers correspond to the M starting storage addresses corresponding to the M test disk numbers one by one. In addition, before the server starts testing the RAID array to be tested, it needs to clear the previously created RAID array to be tested in each test disk to prevent affecting the test results.

[0046] With such a configuration, the server can determine whether to test the RAID array to be tested based on the correspondence between the M virtual test disk numbers and the M test disk numbers corresponding to the M RAID arrays to be tested, and the correspondence between the M virtual starting storage addresses corresponding to the M virtual test disk numbers and the M starting storage addresses corresponding to the M test disk numbers, because if any of the above correspondences is wrong, the test result of the RAID array to be tested will be inaccurate. Therefore, this method ensures the accuracy of the test results and the normal operation of the test work.

[0047] In one embodiment, Figure 2 As shown, Figure 2 A schematic diagram of the connection relationship between the server and the test machine provided in the embodiment of the present application. M RAID arrays to be tested are respectively set on I test machine 300; I test machine 300 is connected to the server 200 through the SSH protocol.

[0048] Specifically, SSH (Secure Shell Protocol) is a confidentiality protocol used for communication between a test machine 300 and a server 200. The server 200 and each test machine 300 are connected via a network cable (not shown in the figure). The server 200 needs to obtain the IP address of each test machine 300 in advance, and send the test data to each test machine 300 based on the SSH protocol according to the IP address of each test machine 300. Each test machine 300 is equipped with multiple test disks.

[0049] In this way, the server 200 can simultaneously perform performance tests on multiple RAID arrays to be tested. The server 200 communicates with each test machine 300 via the SSH protocol, ensuring that test data will not be leaked during the test process, thereby ensuring the accuracy of the test results and the security of the test process.

[0050] Based on the above method embodiment, the present application embodiment also provides a RAID array testing device.

[0051] Preferably, the testing module 32 is further configured to determine that the mth RAID array to be tested is normal if the reading result received by the server is that the nth test data block read by the mth RAID array to be tested is the same as the nth data block written by the server.

[0052] Preferably, the test module 32 is further used to, in the second test mode, write J test data blocks out of the N test data blocks of each test data into any J storage blocks out of the N storage blocks of the test disk corresponding to each RAID array to be tested; instruct each RAID array to be tested to read J test data blocks out of the J storage blocks of the test disk corresponding to each RAID array to be tested; and if the server receives a reading result that the j-th test data block read by the m-th RAID array to be tested is different from the j-th test data block written by the server, determine that the m-th RAID array to be tested is abnormal.

[0053] Preferably, the testing module 32 is further configured to determine that the mth RAID array to be tested is normal if the reading result received by the server is that the jth test data block read by the mth RAID array to be tested is the same as the jth data block written by the server.

[0054] Preferably, the M RAID arrays to be tested pregenerate M virtual test disk numbers corresponding to the M RAID arrays to be tested, and M virtual starting storage addresses corresponding to the M virtual test disk numbers; An acquisition module (not shown in the figure) is used to acquire M test disk numbers corresponding to the M RAID arrays to be tested and M starting storage addresses corresponding to the M test disk numbers; The testing module 32 is further configured to start testing the M RAID arrays to be tested if the M test disk numbers are the same as the M virtual test disk numbers and the M virtual start storage addresses are the same as the M start storage addresses.

[0055] Preferably, the testing module 32 is further configured to stop testing the mth RAID array to be tested if the mth test disk number is different from the mth virtual test disk number and / or the mth virtual starting storage address is different from the mth starting storage address.
