[0066] In order to make the person skilled in the art better understand the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of the present application.

[0067] When multiple SSDs on the server are tested for performance, it is found that the performance of individual disks will be poor, and it is verified that this is related to the uneven allocation of resources, but since the number of disks tested each time is not fixed, a fixed configuration cannot be used to perform core binding operations. Therefore, in the hard disk testing method provided in the present application, a dynamic core binding method is proposed, which automatically associates SSD devices with NUMA nodes, dynamically adjusts the binding of NUMA node CPU cores and SSDs, and evenly distributes and dynamically adjusts the CPU core list to ensure efficient processing of IO operations at the CPU level, thereby avoiding discrepancies between individual disk detection and reality, and ensuring the accuracy of hard disk testing. For details, please refer to Figure 1 , Figure 1 The flowchart of a hard disk testing method in an embodiment of the present application includes the following steps:

[0068] S101, obtain mapping information of hard disks and access nodes.

[0069] The access node is a node in a non-uniform memory access architecture.

[0070] First, briefly describe UMA and NUMA.

[0071] Please refer to Figure 2 , all processors (CPU, Central Processing Unit) access the entire DRAM (Dynamic Random Access Memory, dynamic random access memory, system memory) at the same speed, and the operating system performs memory allocation uniformly to all processors, and only needs to find a free space for the applicant by the memory management module. This memory architecture is a unified memory access (UMA, Unified Memory Architeture).

[0072] Please refer to Figure 3 , numerous processors and massive memory, which may be distributed on multiple different nodes, and processors have different access speeds to different nodes. Accordingly, the memory management module needs to try to make each processor access the nearest memory node to improve system performance. This architecture is called non-uniform memory access (NUMA, NonUniform Memory Access Architecture).

[0073] NUMA architecture essentially divides M CPUs into N groups, each group is connected by IMC BUS bus, each group is called a Node (i.e. node, referred to as access node in this paper), which is similar to a small UMA, and each Node has an integrated memory controller IMC (Intergrated Memory Controller). The CPUs in the group are connected by IMCBUS bus, and the Nodes are connected by QPI (direct link) bus, and the QPI delay is significantly higher than the IMCBUS.

[0074] From Figure 3 It can be seen that the Node in the NUMA architecture has a mapping relationship with the SSD, therefore, in order to realize the balanced allocation of resources, the mapping relationship between the hard disk and the access node can be obtained first.

[0075] In one specific embodiment of the present application, the mapping information between the hard disk and the access node is obtained, comprising:

[0076] Obtaining the corresponding disk symbol of the hard disk to be tested;

[0077] Using the disk symbol to query the hardware configuration information of the hard disk;

[0078] Determining the physical slot position of the hard disk from the hard disk configuration information;

[0079] Using the physical slot position to determine the access node to which the hard disk belongs to obtain the mapping information.

[0080] Among them, using the disk symbol, using the physical slot position to determine the access node to which the hard disk belongs to obtain the mapping information, comprising:

[0081] Using the physical slot position to determine the access node to which the hard disk belongs to construct a mapping table;

[0082] Obtaining the mapping information from the mapping table.

[0083] For the convenience of description, the above steps will be combined for description.

[0084] First, the test engineer records the identifiers (i.e. disk symbols) of the multiple SSD devices to be tested in detail.

[0085] Next, by traversing the SSD devices through the recorded disk symbols, and by querying the system's hardware configuration information, the physical slot positions (i.e., physical slot positions) connected to each SSD device are identified, and these SSDs are classified according to the NUMA nodes (i.e., access nodes) to which they belong. In this way, a detailed mapping table of NUMA nodes and SSD device identifiers can be constructed based on the classification. In this mapping table, multiple SSD device identifiers may be listed under each NUMA node, reflecting the distribution of SSD devices on different NUMA nodes. That is, based on the mapping table, the mapping relationship between the hard disks and the access nodes can be determined, i.e., which access node the hard disk is in, and which hard disks are in the access node.

[0086] S102, determine whether the number of hard disks allocated to the access node is balanced based on the mapping information.

[0087] Since the mapping information can indicate which hard disks are under the access node, the number of hard disks allocated to the access node can be determined based on the mapping information. For example, if there are 2 access nodes, access node 1 has N hard disks, and access node 2 has M hard disks, when N and M are not equal, it can be considered that the number of hard disks allocated to the access node is unbalanced.

[0088] After determining whether the number of hard disks allocated to the access node is balanced, subsequent processing operations can be performed according to the specific judgment result. Specifically, if the judgment result is no, step S103 can be performed, and if the judgment result is yes, step S104 can be performed.

[0089] S103, adjust the number of hard disks allocated to the access node, and return to reacquire the mapping information of the hard disks and the access nodes.

[0090] For example, before adjustment, access node 1 is allocated 3 hard disks, and access node 2 is allocated 5 hard disks. After adjustment, access node 1 is allocated 4 hard disks, and access node 2 is allocated 4 hard disks, or access node 1 is allocated 6 hard disks, and access node 2 is allocated 2 hard disks.

[0091] In order to ensure the efficiency of IO operation, in this embodiment, when it is found that the number of hard disks allocated to the access node is unbalanced, the number of hard disks allocated to the access node can be adjusted to balance the number of hard disks allocated to the access node. After adjusting the number of hard disks allocated to the access node, step S101 is returned to, so that in the case where the number of hard disks allocated to the access node is balanced, step S104 is continued to be executed.

[0092] Of course, in actual application, if the number of hard disks allocated to the access node is adjusted, the number of hard disks allocated to the access node is balanced after adjustment, and then step S101 can not be returned, but step S104 can be directly executed. For example, before adjustment, access node 1 is allocated with 3 hard disks, and access node 2 is allocated with 5 hard disks. When adjustment is performed, the ratio of the total number of hard disks to the number of access nodes is calculated, and the hard disks are allocated according to the ratio, that is, (3+5) / 2=4, 4 hard disks are allocated to access node 1, and 4 hard disks are allocated to access node 2. After re-allocation, the number of hard disks allocated to the two access nodes is balanced, and the operation of step S104 can be directly executed.

[0093] In one specific embodiment of the present application, the number of hard disks allocated to the access node is adjusted, comprising:

[0094] Obtaining the relationship information among the access node, the hard disk and the physical slot position of the hard disk;

[0095] Adjusting the number of hard disks allocated to the access node by using the relationship information, so as to balance the number of hard disks allocated to the access node.

[0096] For the convenience of description, the above steps will be described in combination.

[0097] In order to ensure the optimization of system performance, it is necessary to ensure that the number of SSDs allocated to each NUMA Node is equal. If it is found that the allocation is not uniform, the exact physical slot information of each SSD can be obtained by using the commands provided by the Linux system, such as lspci or lsblk, and a detailed relationship table of the NUMA Node, the SSD disk symbol and the physical slot can be generated according to the information. According to the relationship table, the engineer can adjust the physical connection of the SSD to ensure that the number of SSDs on each NUMA Node reaches balance.

[0098] S104, after the same number of processors are allocated to the hard disks in the access node, the hard disks are tested based on the non-uniform memory access architecture.

[0099] After it is determined that the number of SSDs on each NUMA Node reaches balance, the same number of processors can be allocated to the hard disks in the access node, so that the number of processors allocated to the hard disks is also balanced. In this way, it can be ensured that each hard disk can be allocated with the same number of processors, so as to realize resource balance. After the resource balance allocation is met, the hard disks are tested in the non-uniform memory access architecture, so as to ensure the efficient processing of read and write operations at the processor level, thereby avoiding the situation that the detection of individual disks does not match the actual situation, and the accuracy of the hard disk test can be ensured.

[0100] In one specific embodiment of the present application, the same number of processors is allocated to the hard disks in the access node, comprising:

[0101] Obtaining the number of processors and the number of hard disks corresponding to the access node;

[0102] Allocating the same number of processors to the hard disks in the access node by using the number of processors and the number of hard disks.

[0103] In one specific embodiment of the present application, the same number of processors is allocated to the hard disks in the access node, comprising:

[0104] Obtaining the specified number of processors allocated to the hard disks;

[0105] Calculating the ratio of the number of processors to the number of hard disks;

[0106] Determining whether the hard disks can be allocated to the specified number of processors by using the ratio;

[0107] If yes, obtaining the list of available processors and determining the specified number of processors from the interval area;

[0108] Allocating the determined processors to the hard disks;

[0109] Deleting the allocated processors from the list of available processors;

[0110] If no, determining whether the number of processors is less than the number of hard disks;

[0111] If the number of processors is less than the number of hard disks, triggering an exception troubleshooting process;

[0112] After completing the exception troubleshooting, re-obtaining the mapping information of the hard disks and the access node;

[0113] If the number of processors is greater than or equal to the number of hard disks, determining the target number by using the ratio;

[0114] Obtaining the list of available processors and determining the target number of processors from the interval area;

[0115] Allocating the determined processors to the hard disks;

[0116] Deleting the allocated processors from the list of available processors.

[0117] For ease of description, the above steps will be described in combination.

[0118] Please refer to Figure 4After completing the physical allocation balance of SSDs, the system can traverse each NUMA Node and compare the number of CPU cores on the NUMA Node with the number of SSDs allocated to it (B). Through this comparison, based on the resulting ratio, it can be determined whether each SSD can be allocated to the preset number of CPU cores. If a certain SSD cannot be allocated to sufficient CPU cores, the number of cores that each SSD can be allocated will be reset according to the actual number of CPU cores. When it is found that A is less than B, i.e., it is not possible to guarantee that each SSD is allocated at least one CPU core, an exception handling process will be triggered, which may prompt the replacement of CPUs or the detection of socket connections, etc.

[0119] Considering that the CPU cores on each NUMA Node are distributed in a continuous manner, for example, in two regions of 0-7 and 16-23, the actual number of CPU cores N allocated to each SSD is evenly distributed in these two regions. The specific operation is to select N / 2 CPU cores from each region, and after each selection, the allocated CPU cores are removed from the list of available CPU cores to prevent them from being allocated to other SSDs.

[0120] In this way, it is ultimately possible to ensure that each SSD is allocated the same number of CPU cores. Such a configuration provides a solid foundation for performance testing using fio or other IO testing tools. During testing, by binding specific SSDs to specific CPU cores, the consistency of resource allocation can be ensured, resulting in more accurate and reliable test results. This not only improves the efficiency of testing, but also provides an important reference for the performance optimization of the system.

[0121] In one specific embodiment of the present application, hard disk testing based on a non-uniform memory access architecture includes:

[0122] Binding read and write threads of an input and output testing tool to a processor;

[0123] Using an input and output testing tool to perform performance testing on a target hard disk in a non-uniform memory access architecture.

[0124] For ease of description, the above steps will be combined for description.

[0125] When performing SSD performance testing on a single disk on a NUMA architecture, the read and write threads of fio (an input and output testing tool) are bound to the CPU cores, so that the speed of the SSD will be closer to the theoretical data.

[0126] Wherein, the core binding process is as follows:

[0127] 1. Confirm which NUMA Node the hard disk physically belongs to;

[0128] 2. NUMA Node corresponds to which CPU core (i.e. CPU core, corresponding to processor), from which CPU core is selected;

[0129] 3. The selected CPU core is bound to the hard disk.

[0130] In a specific embodiment of the present application, the core binding process includes:

[0131] Determine the target hard disk from the to-be-tested hard disk record;

[0132] Determine the target access node to which the target hard disk physically belongs by using the mapping table;

[0133] Determine the processors corresponding to the target access node by using the relationship table, and select the target processor from the processors;

[0134] Bind the target processor to the target hard disk;

[0135] Correspondingly, after the binding is completed, the target hard disk is tested based on fio, and after the target hard disk test is completed, the target hard disk is deleted from the to-be-tested hard disk record;

[0136] Determine whether the to-be-tested hard disk record is empty;

[0137] If it is empty, the test is ended; if it is not empty, return to execute the step of determining the target hard disk from the to-be-tested hard disk record.

[0138] The method provided by the embodiment of the present application obtains the mapping information of the hard disk and the access node; wherein the access node is a node in the non-uniform memory access architecture; the mapping information is used to determine whether the number of hard disks allocated by the access node is balanced; if not, the number of hard disks allocated by the access node is adjusted, and the mapping information of the hard disk and the access node is reacquired; if yes, the same number of processors is allocated to the hard disk in the access node, and the hard disk is tested based on the non-uniform memory access architecture.

[0139] The non-uniform memory access architecture involves different access speeds of a processor to a hard disk. In the present application, before performing hard disk testing, a mapping relationship between the hard disk and an access node is first obtained. Then, based on the mapping relationship, it is determined whether the number of hard disks allocated to the access node is balanced. If not, the number of hard disks allocated to the access node is adjusted, and the mapping information between the hard disk and the access node is reobtained. If balanced, the same number of processors can be further allocated to the hard disks in the access node. In this way, it can be ensured that each hard disk can be allocated to the same number of processors, thereby achieving resource balancing. After satisfying the resource balanced allocation, the hard disk testing in the non-uniform memory access architecture can ensure efficient processing of read and write operations at the processor level, thereby avoiding the situation that the detection of individual disks does not match the actual situation, and the accuracy of the hard disk testing can be ensured.

[0140] For ease of understanding, the hard disk testing method will be described in detail below in combination with a specific application example.

[0141] Please refer to Figure 5 , assuming that the server NUMA node 1 (access node 1) and NUMA node 2 (access node 2) are two NUMA nodes (of course, in actual applications, there can be more, and in this example, for ease of description, two nodes are described), 8 SSDs, according to the physical slot position, it can be found that there are 5 SSDs in the NUMA node 1, and the other 3 SSDs in the NUMA node 2. After performing the resource adjustment in the disk testing method provided in the above embodiment, each NUMA node can have 4 SSDs. The CPU core allocated to each SSD is shown in the following table.

[0142]

[0143] It can be seen that the hard disk testing method provided by the present application has the following technical effects:

[0144] 1. Improve system performance: by ensuring that each NUMA Node is allocated to the same number of SSDs, the load of data processing is balanced, the data access across NUMA Nodes is reduced, the access delay is reduced, and the efficiency of data processing is improved.

[0145] 2. Optimize resource utilization: by balancing the number of SSDs on each NUMA Node, the CPU resources and storage resources are reasonably allocated, so that each resource can be fully utilized, and the waste of resources is avoided.

[0146] 3. Enhance the consistency of data processing: By ensuring that each SSD can be allocated the same number of CPU cores, it guarantees that each SSD has enough processing power when performing IO operations, thereby improving the consistency and stability of data processing.

[0147] 4. Simplify system management: The automated mapping and adjustment process simplifies the work of system administrators, reduces the need for manual configuration, and reduces the complexity and likelihood of management errors.

[0148] 5. Improve system stability: By reasonably allocating SSDs and CPU cores, it reduces the risk of performance bottlenecks and system crashes caused by uneven resource allocation, improving the overall stability of the system.

[0149] 6. Improve test accuracy: When performing IO performance tests, by binding specific CPU cores and SSDs, it can more accurately measure storage performance and avoid test result deviations caused by resource competition.

[0150] 7. Facilitate troubleshooting: By generating a NUMA Node and SSD drive letter and physical slot relationship table, administrators can quickly locate misconfigured or hardware failure locations, facilitating troubleshooting and repair.

[0151] That is, in this application, an innovative automated NUMA-Aware SSD allocation mechanism is introduced, which automatically associates SSD devices with NUMA nodes and ensures that each node allocates the same number of SSDs, reducing manual intervention and improving configuration efficiency and accuracy. At the same time, the SSD classification method based on physical slot as a hardware resource management strategy ensures data access locality, further optimizing performance.

[0152] Specifically, by creating a NUMA Node and SSD device identifier list mapping table, it provides engineers with a clear resource allocation view, facilitating quick identification and resolution of resource configuration issues.

[0153] In addition, the technical solution provided in this application also ensures the consistency of resource allocation and maintains the balance of system performance. Among them, the dynamic adjustment strategy of CPU core and SSD binding, by evenly distributing and dynamically adjusting the CPU core list, ensures efficient processing of IO operations at the CPU level.

[0154] Finally, the scheme contains a troubleshooting and exception handling mechanism, which investigates and handles abnormal situations where not every SSD can be allocated at least one CPU core, enhancing the robustness and reliability of the system.

[0155] Corresponding to the above method embodiments, the embodiments of the present application also provide a hard disk testing device. The hard disk testing device described below can be correspondingly referred to the hard disk testing method described above.

[0156] Referring to Figure 6 As shown in the figure, the device comprises the following modules:

[0157] The mapping information acquisition module 101 is configured to acquire mapping information of the hard disks and the access nodes; wherein the access nodes are nodes in the non-uniform memory access architecture.

[0158] The node hardware balance judgment module 102 is configured to determine, by using the mapping information, whether the number of hard disks allocated to the access nodes is balanced.

[0159] The node hardware balance processing module 103 is configured to, if the number of hard disks allocated to the access nodes is not balanced, adjust the number of hard disks allocated to the access nodes, and return to acquire the mapping information of the hard disks and the access nodes.

[0160] The hard disk testing module 104 is configured to, if the number of hard disks allocated to the access nodes is balanced, assign the same number of processors to the hard disks in the access nodes, and then perform hard disk testing based on the non-uniform memory access architecture.

[0161] The device provided by the embodiments of the present application is configured to acquire the mapping information of the hard disks and the access nodes; wherein the access nodes are nodes in the non-uniform memory access architecture; determine, by using the mapping information, whether the number of hard disks allocated to the access nodes is balanced; if not, adjust the number of hard disks allocated to the access nodes, and return to acquire the mapping information of the hard disks and the access nodes; and if yes, assign the same number of processors to the hard disks in the access nodes, and then perform hard disk testing based on the non-uniform memory access architecture.

[0162] The non-uniform memory access architecture involves different access speeds of the processors to the hard disks. In the present application, the mapping relationship between the hard disks and the access nodes is acquired before hard disk testing. Then, it is determined whether the number of hard disks allocated to the access nodes is balanced based on the mapping relationship.
