Description

Technical Field

[0001] The present invention relates to the field of storage technology, and in particular to a method, device, equipment and medium for testing the performance of a compressed volume of a storage device. Background Art

[0002] Data compression is a technical method that reduces data volume to reduce storage space and improve transmission, storage, and processing efficiency without losing information. Alternatively, data can be reorganized according to a specific algorithm to reduce redundancy and storage space. With the rapid development of the mobile internet, compressed volumes provided by storage devices are widely used by organizations across various industries. The performance of compressed volumes must also meet the demands of these customers in a variety of demanding scenarios. Therefore, performance testing of compressed volumes is becoming increasingly important.

[0003] Currently, in traditional storage performance testing of compressed volumes, if there's no data in the compressed volume, when the test host sends a read I / O command, the compression module returns 0 directly, without decompressing the data. Therefore, read performance results on a data-free compressed volume can be very high. Furthermore, due to the garbage collection mechanism within the storage compression module, when a specified data block is repeatedly written, the compression module performs background garbage collection, impacting the write performance of the compressed volume. Therefore, accurately evaluating the performance of compressed volumes is a challenge that needs to be addressed. Summary of the Invention

[0042] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the embodiments of the present invention are further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0043] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. Subsequent embodiments will not explain this one by one.

[0044] In one embodiment, please refer to Figure 1 As shown, the present invention provides a method 100 for testing the performance of a compressed volume of a storage device. Specifically, the method includes the following steps:

[0045] Step 101, obtaining the size of the compressed volume and calculating the number of sectors of the compressed volume according to the size of the compressed volume;

[0046] Step 102: Divide the compressed volume into a plurality of test areas based on the number of sectors, wherein each test area corresponds to a type of IO operation;

[0047] Step 103, determining whether each test area includes a read test;

[0048] Step 104: In response to the IO operation type corresponding to a certain test area including a read test, data is first written to the certain test area before executing the read test, and then a test command is issued according to the IO operation type corresponding to the certain test area;

[0049] Step 105 : In response to the IO operation type corresponding to a certain test area not including a read test, a test command is directly issued according to the IO operation type corresponding to the certain test area.

[0050] The above-mentioned method for testing the performance of compressed volumes of storage devices divides the compressed volumes into different test areas, ensuring that no duplicate data is generated in each test, avoiding triggering garbage collection and affecting test performance. At the same time, the adjustment of the test sequence and the pre-embedding of test data improve the accuracy of the compressed volume performance test, which helps to improve the design level and quality of storage products and enhance product competitiveness.

[0051] In some embodiments, the aforementioned step 102 of dividing the compressed volume into a plurality of test areas based on the number of sectors includes:

[0052] Determine whether each IO operation type has a designated test area;

[0053] In response to no test area being specified for all IO operation types, evenly distributing the number of sectors into a plurality of test areas, such that each test area corresponds to one IO operation type and different test areas include the same number of sectors;

[0054] In response to all IO operation types having designated test areas, sectors corresponding to the designated test areas are used as test areas corresponding to a certain IO operation type.

[0055] In some embodiments, the aforementioned step 102 of dividing the compressed volume into a plurality of test areas based on the number of sectors further includes:

[0056] In response to the fact that some of all IO operation types have designated test areas and some of them do not have designated test areas, the corresponding test areas are first divided for the corresponding IO operation types based on the sectors corresponding to each designated test area, and then the remaining unallocated sectors are evenly allocated to the IO operation types corresponding to each unallocated test area.

[0057] In some embodiments, the IO operation types include random read of a preset IO size, random write of a preset IO size, random read and write of a preset IO size, sequential read of a preset IO size, sequential write of a preset IO size, and sequential read and write of a preset IO size.

[0058] In another embodiment, in order to facilitate understanding of the solution of the present invention, the following takes six specific IO operation types as examples: 2KB random read, 4KB random read, 8KB random read, 2KB random write, 4KB random write, 8KB random write as examples, please combine Figure 2 As shown, this embodiment provides another storage device compressed volume performance test method 200, and the specific implementation steps are as follows:

[0059] Step 201: Get the size of the compressed volume and calculate the number of sectors in the compressed volume;

[0060] Step 202: Divide different test areas according to the IO data type and sector quantity required for testing.

[0061] In step 203, if the compressed volume test area is not specified, the test area is evenly distributed according to the number of IO types tested. For example, assuming there are 12,000 sectors, each of the above six IO operation types corresponds to 2,000 sectors.

[0062] In step 204, if a test area for the compressed volume is specified, the test area is generated according to the specified rules. For example, it is pre-specified that 2KB random reads correspond to sectors 1 to 1000, 4KB random reads correspond to sectors 1001 to 3000, 8KB random reads correspond to sectors 3001 to 5000, 2KB random writes correspond to sectors 5001 to 6000, 4KB random writes correspond to sectors 6001 to 8000, and 8KB random writes correspond to sectors 8001 to 10000.

[0063] Step 205: Generate test sequence rules based on the IO test read / write type;

[0064] Step 206: If the IO test type is to test the compressed volume read performance, data is first written to the area divided in step 202. The pre-embedded data volume is the amount of data required to test the compressed volume read performance. Then, the read performance test is performed.

[0065] In step 207, if the IO test type is to test the compressed volume write performance, the data write performance test is directly performed based on the area divided in step 202. For example, 2KB random read, 4KB random read, and 8KB random read all include read tests, so data must be pre-written to the corresponding sectors before reading.

[0066] Step 208: Integrate the rules of steps 202 and 205 to generate compressed volume IO delivery rules;

[0067] In step 209, the IO delivery rules generated in step 208 are used to perform a performance test on the compressed volume. For example, the sectors corresponding to 2KB random read, 4KB random read, 8KB random read, and 2KB random write are first written to and then tested for data read. For 2KB random write, 4KB random write, and 8KB random write, data can be directly written to the corresponding sectors for testing.

[0068] This embodiment of a storage device compressed volume performance testing method divides the compressed volume into different test areas, ensuring that each test does not generate duplicate data, thus avoiding triggering garbage collection and impacting test performance. Furthermore, by adjusting the test sequence and pre-embedding test data, the accuracy of the compressed volume performance test is improved. This improves product design and quality, thereby enhancing product competitiveness.

[0074] The second issuing module 305 is configured to issue a test command directly according to the IO operation type corresponding to a certain test area in response to the IO operation type corresponding to the certain test area not including a read test.

[0075] The above-mentioned storage device compressed volume performance testing device divides the compressed volume into different test areas, ensuring that no duplicate data is generated in each test, avoiding triggering garbage collection and affecting test performance.
