[0002] DIMM (Dual-Inline-Memory-Modules) is a dual-inline memory module, which provides a 64-bit data channel. The memory DIMM slots of the server CPU have various memory configurations. When users actually use it, some DIMM memory configurations are often not optimal in terms of system performance, which will cause the system to not work in the best state, fail to give full play to the server's capabilities, and cause a waste of customer resources.

[0003] At present, the configuration of the DIMM in the existing server slots is usually installed according to the method recommended in the manual. However, since it is a manual operation and the configuration often changes with demand, errors are inevitable. In case of errors, the system may run normally, but the performance is not optimal. Customers are not likely to pay attention to this, which leads to the product being not intelligent enough and there is a possibility that the product cannot fully exert its optimal performance. Summary of the invention

[0011] According to the number of CPUs and memory capacity in the current server, the corresponding configuration scheme combination is queried in the DIMM memory configuration recommendation table. If a completely matching configuration scheme can be found and the corresponding priority level is the highest in the scheme combination, it is considered to meet the performance optimization requirements.

[0012] In one embodiment, the step of judging whether the current server DIMM memory configuration scheme meets the optimal performance according to the DIMM memory configuration recommendation table further includes:

[0013] If a fully matching configuration solution can be found but the priority level of the queried configuration solution is not the highest among the solution combinations, it is considered that it does not meet the performance optimization requirement.

[0014] If the current server DIMM memory configuration scheme is not found in the DIMM memory configuration recommendation table, it is considered that it does not meet the optimal performance.

[0015] In one of the embodiments, the DIMM slot number in the DIMM memory configuration recommendation table includes three digits, wherein the first digit represents the CPU number corresponding to the DIMM slot, the second digit represents the number of the CPU memory controller corresponding to the DIMM slot, and the third digit represents the identification bit of the distance between the DIMM slot and the CPU memory controller.

[0037] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0038] Currently, if Figure 1 As shown, the configuration of existing server DIMM memory in the slot is usually installed in the way recommended in the manual, but because it is a manual operation and the configuration often changes with demand, it is inevitable that there is a possibility of error. In case of error, the system may run normally, but the performance is not optimal. Customers are not easy to pay attention to this, and there is a possibility that the product cannot fully exert the optimal performance. It can be seen that the traditional solution relies on personal ability to make manual judgments, which has uncertain factors, and there is the possibility of missing evaluations and random insertion methods. When a certain DIMM memory is configured inappropriately, the system performance may not be optimal, affecting the performance of the system, and thus affecting the customer's business experience.

[0039] Based on this, the present invention provides a configuration detection method based on DIMM memory slots, aiming to achieve intelligent management of server DIMM memory configuration.

[0040] In one embodiment, Figure 2 As shown, a configuration detection method based on DIMM memory slots is provided, the method comprising:

[0041] Step 202, creating a DIMM memory configuration recommendation table, in which DIMM slot number combinations for installing memory modules and priorities corresponding to the DIMM slot number combinations are listed according to the number of CPUs and memory capacity as indexes;

[0042] Step 204: After the system is powered on, detect and obtain the current server DIMM memory configuration scheme;

[0043] Step 206, judging whether the current server DIMM memory configuration scheme meets the optimal performance according to the DIMM memory configuration recommendation table;

[0044] Step 208: If the current server DIMM memory configuration scheme is optimal, the server operates normally; if the current server DIMM memory configuration scheme is not optimal, the current server DIMM memory configuration is adjusted according to the optimal DIMM slot number combination after the system is powered off.

[0045] In this embodiment, a configuration detection method based on DIMM memory slots is provided. The method establishes a DIMM memory configuration recommendation table for the system. When powered on, the existing actual DIMM memory configuration is compared with the system's DIMM memory configuration recommendation table for matching, a comprehensive evaluation is given, the rationality of the configuration is judged, and instruction information is provided to the customer through alarm information to help the customer take measures to avoid improper configuration and reduce performance degradation caused by configuration reasons, thereby ultimately achieving intelligent management of server component configuration.

[0046] First, a DIMM memory configuration recommendation table is created, in which DIMM slot number combinations for installing memory modules and priorities corresponding to the DIMM slot number combinations are listed according to the number of CPUs and memory capacity as indexes.

[0047] Specifically, a DIMM memory configuration recommendation table is established within the server system. This table mainly describes the recommended priority of the system from the performance dimension. According to the signal integrity (SI) capability and performance test results of the server system, it is first classified based on the number of CPUs and memory capacity, and the performance priority of each specific DIMM slot is given.

[0048] like Figure 3 As shown in the figure, a DIMM memory configuration recommendation table is established based on the number of CPUs and memory capacity as indexes, forming a series of configuration lists. Each list lists in detail the combination of DIMM slot numbers corresponding to the installed memory modules:

[0049] {x0y0z0, x1y1z1, …, x p y p z p}

[0050] And each group of lists corresponds to a scheme number and a preference level. The smaller the preference level number, the higher the preference level, for example, 0 has a higher priority than 1.

[0051] These lists and priority levels are mainly based on the memory test results in the R&D stage and the recommendations of CPU manufacturers. When the number of CPUs and memory capacity are determined, the better the performance of the corresponding DIMM memory configuration list, the higher the priority level given. If the performance of the corresponding DIMM memory configuration list is very poor, or it is not recommended for customers to use it, it will be directly deleted from the DIMM memory configuration recommendation table. This DIMM memory configuration recommendation table is pre-stored in a specified data area for query, retrieval and judgment after the server is powered on after startup.

[0052] In one of the embodiments, the DIMM slot number in the DIMM memory configuration recommendation table includes three digits, wherein the first digit represents the CPU number corresponding to the DIMM slot, the second digit represents the number of the CPU memory controller corresponding to the DIMM slot, and the third digit represents the identification bit of the distance between the DIMM slot and the CPU memory controller.

[0053] Specifically, the DIMM slot numbering rules are as follows: Figure 4As shown, the server DIMM memory slots can be numbered according to a certain rule, with a total of 3 digits. The first digit x represents the number of the CPU corresponding to the DIMM slot, the second digit y represents the number of the memory controller of the CPU corresponding to the DIMM slot, and the third digit z represents the distance between the DIMM slot and the CPU. 0 represents the closest, 1 represents the second closest, and the larger the number, the farther. In this way, the corresponding positions of the DIMM slots of the entire server can be uniformly numbered, which is convenient for unified planning of memory resources. The final number is xyz. For example, the slot numbered: 040 refers to the DIMM slot where the memory controller 4 (MC4) of CPU0 is closest to the CPU layout.

[0054] When the system is powered on, the system evaluates the existing DIMM memory configuration and performs server configuration detection. If the existing DIMM memory configuration meets the requirements for optimal system configuration, the server will run normally. Otherwise, if it does not meet the requirements for optimal performance, an alarm will pop up to remind the customer, indicating that the DIMM memory configuration does not meet the requirements for optimal system performance. Only after the customer takes measures can the system be powered on again and run normally, so that the server system can finally reach the optimal state, thereby making full use of memory resources. The measures here are usually to power off the system and readjust the DIMM memory configuration.

[0055] In the above embodiment, by creating a DIMM memory configuration recommendation table, the DIMM slot number combination for installing the memory stick and the priority corresponding to the DIMM slot number combination are listed in the DIMM memory configuration recommendation table according to the number of CPUs and memory capacity as indexes; after the system is powered on, the current server DIMM memory configuration scheme is detected and obtained; according to the DIMM memory configuration recommendation table, it is judged whether the current server DIMM memory configuration scheme meets the optimal performance; if the current server DIMM memory configuration scheme is already optimal, the server works normally; if the current server DIMM memory configuration scheme is not optimal, the current server DIMM memory configuration is adjusted according to the optimal DIMM slot number combination after the system is powered off. The present invention establishes a DIMM memory configuration recommendation table for the system, compares the existing actual DIMM memory configuration with the system's DIMM memory configuration recommendation table when powered on, judges the rationality of the configuration, and provides instruction information to customers through alarm information, which can help customers take measures to avoid improper configuration, reduce performance degradation caused by configuration reasons, and finally realize intelligent management of server component configuration.

[0056] In one embodiment, a configuration detection method based on DIMM memory slots is provided, wherein the step of judging whether the current server DIMM memory configuration scheme meets the optimal performance according to the DIMM memory configuration recommendation table further includes:

[0057] According to the number of CPUs and memory capacity in the current server, the corresponding configuration scheme combination is searched in the DIMM memory configuration recommendation table. If a completely matching configuration scheme can be found and the corresponding priority level is the highest in the scheme combination, it is considered to meet the performance optimization requirement;

[0058] If a fully matching configuration scheme can be found but the priority level corresponding to the queried configuration scheme is not the highest in the scheme combination, it is considered that it does not meet the optimal performance; if the current server DIMM memory configuration scheme is not found in the DIMM memory configuration recommendation table, it is considered that it does not meet the optimal performance.

[0059] Specifically, please refer to Figure 5 The power-on warning judgment process shown is as follows:

[0060] When the system is powered on, the DIMM memory actually configured in the server is detected and read. Each DIMM slot is connected to the CPU through the I2C bus. The CPU can easily obtain memory module information through the I2C bus, including whether a memory module is installed in the DIMM slot.

[0061] After obtaining the actual DIMM memory configuration, the server will determine whether the current configuration is optimal in performance in combination with the DIMM memory configuration recommendation table. If it is optimal, the server will work normally. If it is not optimal, an alarm message will pop up to remind the customer. A recommended configuration list can also be provided here. The customer takes measures, usually adjusting the DIMM memory configuration after powering off, and then powering on again.

[0062] The specific method for determining the best performance is as follows:

[0063] First, find the corresponding configuration scheme group according to the number of CPUs and memory capacity, such as A0~Am, and then search from these m configuration lists to see whether the currently obtained configuration list exists. If a completely matching configuration scheme can be found, and the priority level is the highest in the scheme group, it is considered to meet the performance optimization requirements. Otherwise, it is considered to not meet the performance optimization requirements.

[0064] There are two situations that do not meet the optimal performance. One is that a fully matching configuration solution can be found, but the priority is not optimal; the other is that the current actual configuration list combination cannot be found in the DIMM memory configuration recommendation table, indicating that this configuration is not recommended or disabled and is not included in the recommendation table. Both situations do not meet the optimal performance and require measures to be taken to adjust.

[0065] In this embodiment, the problems caused by improper server configuration can be completely solved, the customer experience can be improved, the server performance can be optimized, and the operation can be more intelligent.

[0066] It should be understood that although Figure 1-Figure 5The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 1-Figure 5 At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.

[0072] In one embodiment, the determination module 603 is further used to:

[0073] According to the number of CPUs and memory capacity in the current server, the corresponding configuration scheme combination is queried in the DIMM memory configuration recommendation table. If a completely matching configuration scheme can be found and the corresponding priority level is the highest in the scheme combination, it is considered to meet the performance optimization requirements.

[0074] In one embodiment, the determination module 603 is further used to:

[0075] If a fully matching configuration solution can be found but the priority level of the queried configuration solution is not the highest among the solution combinations, it is considered that it does not meet the performance optimization requirement.

[0076] If the current server DIMM memory configuration scheme is not found in the DIMM memory configuration recommendation table, it is considered that it does not meet the optimal performance.
