[0028] This embodiment provides a method that runs on the aforementioned mobile terminal. Figure 2 This is a flowchart of a monitoring method for a mirror caching system according to an embodiment of this application, such as... Figure 2 As shown, the process includes the following steps:

[0029] Step S202: When the image caching system is in the first working mode, obtain the first real-time performance of the image caching system, wherein the first real-time performance is used to characterize the real-time performance of image caching synchronization through the image caching system.

[0030] The aforementioned mirrored caching system can be a system that stores an exact copy of data from one disk on another disk. The first operating mode mentioned above can be the initial operating mode of the mirrored caching system pre-configured by the user; for example, it could be normal mode, but it is not limited to this. The specific mode can be set by the user according to actual needs. The first real-time performance mentioned above can be the synchronous real-time performance of each module in the mirrored caching system when obtaining the current business model, which can be represented as A, but is not limited to this.

[0031] In an optional embodiment, when the current array needs to be stored, it can first be determined whether the mirror caching system is in the first working mode. When it is determined that the mirror caching system is in the first working mode, the first real-time performance of the mirror caching system can be obtained. The first real-time performance can be the real-time performance of mirror cache synchronization through the mirror caching system.

[0032] In step S204, in response to the first real-time performance being less than the first preset threshold, the mirror caching system is controlled to switch to the second working mode.

[0033] The aforementioned first preset threshold can be set by the user in advance to determine whether the first real-time performance meets the requirements of the first working mode of the mirror caching system. It can be expressed as C1*M1, but is not limited to this. Here, C1 represents the theoretical performance of mirror cache synchronization in the mirror caching system, and M1 can be a percentage set by the user in advance. The specific value can be set by the user according to actual needs. In this embodiment, 75% is used as an example, but it is not limited to this. The aforementioned second working mode can be a working mode set by the user in advance that places higher demands on the mirror caching system. It can be a high-reliability mode, but is not limited to this. In the second working mode, the mirror caching system has a lower fault tolerance rate for sudden failures, so fault prediction is necessary.

[0034] In one optional embodiment, when the first real-time performance of the image caching system is less than a first preset threshold, it indicates that the first real-time performance of the image caching system does not meet the requirements of the first working mode. At this time, the working mode of the image caching system can be switched to the second working mode.

[0035] Step S206: When the mirror caching system is in the second working mode, obtain the second real-time performance of the mirror caching system, wherein the second real-time performance is used to characterize the real-time performance of writing dirty data to disk through the mirror caching system.

[0036] The aforementioned second real-time performance can be the real-time performance of each module in the mirror caching system when it obtains dirty data and writes it to disk, which can be represented as B, but is not limited to this.

[0037] In one optional embodiment, when the image caching system switches to the second working mode, the second real-time performance of the image caching system can be obtained, wherein the second real-time performance may be the real-time performance of writing dirty data to disk through the image caching system.

[0038] Step S208: In response to the first real-time performance being less than the second preset threshold, or the second real-time performance being less than the third preset threshold, an alarm message is output, wherein the alarm message is used to indicate that an anomaly has occurred in the image caching system.

[0039] The aforementioned second preset threshold can be a threshold set by the user in advance to determine whether the first real-time performance of the image caching system meets the requirements of the second working mode. It can be expressed as C1*M2, but is not limited to this. M2 is a percentage set by the user in advance; the specific value can be set by the user according to actual needs. In this embodiment, 80% is used as an example, but it is not limited to this. The aforementioned third preset threshold can be a threshold set by the user in advance to determine whether the second real-time performance of the image caching system meets the requirements of the second working mode. It can be expressed as D1*M3, but is not limited to this. D1 represents the theoretical performance of dirty data write-to-disk in the image caching system, and M3 is a percentage set by the user in advance; the specific value can be set by the user according to actual needs. In this embodiment, 90% is used as an example, but it is not limited to this. The aforementioned alarm information can be any one or more, reflecting information indicating an anomaly in the image caching system, and can include, but is not limited to: voice, text, video, images, etc.

[0040] In one optional embodiment, when the working mode of the mirror caching system switches to the second working mode, it can be determined whether the first real-time performance is less than the second preset threshold, and it can also be determined simultaneously whether the second real-time performance is less than the third preset threshold. When the first real-time performance is less than the second preset threshold, or the second real-time performance is less than the third preset threshold, it indicates that the mirror caching system has malfunctioned. At this time, alarm information can be output through voice, text, video, etc. For example, the alarm information "The mirror caching system has malfunctioned, please handle it in time" can be broadcast by voice, or the alarm information "The mirror caching system has malfunctioned, please handle it in time" can be displayed by the display module in the mirror caching system, or the alarm information "The mirror caching system has malfunctioned, please handle it in time" can be output by both voice and text at the same time, but it is not limited to these.

[0041] Through the above steps, the working modes of the image caching system can be divided, achieving the goal of timely monitoring of the image caching system. Furthermore, by monitoring the image caching performance and dirty data disk persistence performance under different working modes, the goal of accurate monitoring of the image caching system can be achieved. Therefore, the problem of low monitoring accuracy of image caching systems in related technologies can be solved, and the monitoring accuracy of image caching systems can be improved.

[0042] The entity performing the above steps can be a terminal or a server, but is not limited to these.

[0043] In an exemplary embodiment, in response to a first real-time performance being less than a second preset threshold, or a second real-time performance being less than a third preset threshold, an alarm message is output, including: in response to the first real-time performance being less than the second preset threshold, outputting a first alarm message, wherein the first alarm message is used to characterize an abnormal front-end pressure of the image caching system; and in response to the second real-time performance being less than the third preset threshold, outputting a second alarm message, wherein the second alarm message is used to characterize an abnormality of the system disk of the image caching system.

[0044] The first alarm message mentioned above can be any one or more, output through text, voice, images, video, etc., to warn of abnormal front-end pressure on the image caching system. The second alarm message mentioned above can be any one or more, output through text, voice, images, video, etc., to warn of abnormality on the system disk of the image caching system.

[0045] In one optional embodiment, when the first real-time performance is less than the second preset threshold, a first alarm message “The front-end pressure of the mirror cache system is too high, please adjust the pressure in time” can be output by voice. The first alarm message “The front-end pressure of the mirror cache system is too high, please adjust the pressure in time” can also be output by both voice and video at the same time, but it is not limited to this. The first alarm message is used to indicate that the front-end pressure of the mirror cache system is abnormal.

[0046] In another optional embodiment, when the second real-time performance is less than the third preset threshold, a second alarm message "The system disk of the image cache system has failed, please replace the system disk in time" can be output by voice. The second alarm message "The system disk of the image cache system has failed, please replace the system disk in time" can also be output by both text and voice at the same time, but it is not limited to this. The second alarm message is used to indicate that the system disk of the image cache system has failed.

[0047] In one exemplary embodiment, in response to a first real-time performance being less than a second preset threshold, the method further includes: controlling the front-end pressure of the mirror caching system to be less than or equal to the first preset pressure.

[0048] The aforementioned first preset pressure can be a maximum percentage of pressure set by the user to ensure the normal operation of the front-end of the image caching system. It can be represented as E2, but is not limited to this. It should be noted that the user can set the value of E2 according to their specific needs. In this embodiment, 85% is used as an example, but it is not limited to this. When the front-end pressure is less than or equal to the first preset pressure, the front-end of the image caching system can operate normally.

[0049] In one optional embodiment, when the first real-time performance is less than the second preset threshold, it indicates that the image caching system has malfunctioned. At this time, the front-end pressure of the image caching system can be controlled to be less than or equal to the first preset pressure, so that the image caching system can continue to work normally.

[0050] In an exemplary embodiment, in response to a second real-time performance being less than a third preset threshold, the method further includes: outputting a first prompt message, wherein the first prompt message is used to prompt the system disk to be replaced.

[0051] The aforementioned first prompt message can be any one or more, output through voice, text, images, video, etc., and can prompt for the replacement of the system disk.

[0052] In one optional embodiment, when the second real-time performance is less than the third preset threshold, it indicates that the image caching system has malfunctioned. At this time, a prompt message "The image caching system has malfunctioned, do you want to replace the system disk?" can be output via voice. Alternatively, the prompt message "The image caching system has malfunctioned, do you want to replace the system disk?" can be output via both voice and text simultaneously, so that the user can replace the system disk of the image caching system.

[0053] In one exemplary embodiment, the method further includes: in response to the front-end pressure of the image caching system being less than a second preset pressure, testing the image caching system to obtain test results, wherein the test results are used to characterize whether the image caching system is normal; in response to an anomaly in the image caching system, updating the preset performance parameters of the image caching system to obtain target performance parameters; and determining a first preset threshold, a second preset threshold, and a third preset threshold based on the target performance parameters.

[0054] The aforementioned second preset pressure value can be a minimum percentage of pressure set by the user to ensure the normal operation of the front end of the image caching system. It can be represented as E1, but is not limited to this. It should be noted that the user can set the value of E1 according to their actual usage needs. In this embodiment, 20% is used as an example, but it is not limited to this. The aforementioned preset performance parameters can be the initial performance parameters of the image caching system set by the user in advance, and may include, but are not limited to, C1 and D1. The specific values ​​can be set by the user according to actual usage needs, and are not limited in this embodiment. The aforementioned target performance parameters can be the performance parameters obtained after updating the preset performance parameters.

[0055] In one optional embodiment, when the front-end pressure of the image caching system is less than the second preset pressure, the image caching system can be tested to obtain the test result of whether the image caching system is normal; when the test result of the image caching system being abnormal is obtained, the preset performance parameters of the image caching system can be updated to obtain the target performance parameters; finally, based on the target performance parameters, the first preset threshold, the second preset threshold, and the third preset threshold can be updated.

[0056] In an exemplary embodiment, the preset performance parameters include: a first preset performance and a second preset performance. Testing the image caching system to obtain test results includes: acquiring the first test performance and the second test performance of the image caching system, wherein the first test performance characterizes the real-time performance of image cache synchronization via the image caching system during the test, and the second test performance characterizes the real-time performance of dirty data write-to-disk in the image caching system during the test; obtaining a first performance difference based on the first test performance and the first preset performance, and obtaining a second performance difference based on the second test performance and the second preset performance; determining the test result as normal for the image caching system in response to the first performance difference being less than the first preset difference and the second performance difference being less than the second preset difference; and determining the test result as abnormal for the image caching system in response to the first performance difference being greater than or equal to the first preset difference, or the second performance difference being greater than or equal to the second preset difference.

[0057] The aforementioned first preset performance can be C1, the second preset performance can be D1, the aforementioned first test performance can be C2, and the aforementioned second test performance can be D2. C2 represents the real-time performance of the image caching system in the test scenario, and D2 represents the real-time performance of the image caching system for dirty data write-to-disk in the test scenario. Specific values ​​can be set by the user according to actual usage needs and are not limited in this embodiment. The aforementioned first performance difference can reflect the rate of the image caching channel, which can be expressed as |(C2-C1) / C1|, but is not limited to this. The first preset difference can be the minimum rate at which the image caching channel can normally cache data, which can be expressed as F. Specific values ​​can be set by the user according to their needs. In this embodiment, 15% is used as an example, but it is not limited to this. The aforementioned second performance difference can reflect the rate of the dirty data write-to-disk channel, which can be expressed as |(D2-D1) / D1|, but is not limited to this. The second preset difference can be the minimum rate at which the dirty data write-to-disk channel can normally cache data, which can be expressed as H. Specific values ​​can be set by the user according to their needs. In this embodiment, 10% is used as an example, but it is not limited to this.

[0058] In an alternative embodiment, first, the first test performance and the second test performance of the mirror cache system can be obtained; secondly, based on the first test performance and the first preset performance, the first performance difference can be obtained, and based on the second test performance and the second preset performance, the second performance difference can be obtained; in response to the first performance difference being less than the first preset difference and the second performance difference being less than the second preset difference, it is determined that the test result is that the mirror cache system is normal; in response to the first performance difference being greater than or equal to the first preset difference or the second performance difference being greater than or equal to the second preset difference, it is determined that the test result is that the mirror cache system is abnormal.

[0059] In another alternative embodiment, every time period T1 (for example, it can be 15 days), when the front-end pressure is less than the percentage E1, a round of simulation pressure test with a duration of T2 (for example, it can be 30 minutes) is performed, and the real-time performance C2 of mirror cache synchronization and the real-time performance D2 when dirty data is written to disk are obtained respectively. If |(C2 - C1) / C1| < F and |(D2 - D1) / D1| < H (10%), it indicates that the mirror cache system is normal; if |(C2 - C1) / C1| ≥ F or |(D2 - D1) / D1| ≥ H, it indicates that the mirror cache system is abnormal.

[0060] In an exemplary embodiment, in response to the mirror cache system being abnormal, the method further includes: retesting the mirror cache system a preset number of times to obtain the test results of the preset number of times; in response to the test results of the preset number of times being the same, updating the first preset performance based on the first test performance.

[0061] The above preset number of times can be set in advance by the user and is the number of times that can test a normal mirror cache system. The specific value can be set according to the user's needs. In this embodiment, it is illustrated by taking 3 times as an example, but it is not limited thereto.

[0062] In an alternative embodiment, when the mirror cache system is abnormal, the mirror cache system can be retested a preset number of times to obtain the test results of the preset number of times. In response to the test results of the preset number of times all indicating that the mirror cache system is abnormal, the first preset performance can be updated through the first test performance. For example, C2 can be used to replace C1, and D2 can be used to replace D1.

[0063] In an exemplary embodiment, the method further includes: in response to the test results of the preset number of times being the same, outputting a third warning message and a second prompt message, where the third warning message is used to characterize the abnormality of the preset performance parameter, and the second prompt message is used to prompt to update the preset performance parameter.

[0064] The aforementioned third alarm information can be any one or more, and can be output through voice, text, images, video, etc., to warn of abnormal preset performance parameters; the aforementioned second prompt information can be any one or more, and can be output through voice, text, images, video, etc., to prompt for updating the preset performance parameters.

[0065] In one optional embodiment, in response to the fact that the image caching system has an anomaly after a preset number of test results, a third alarm message "Preset performance parameters are abnormal, please handle it in time" can be output by voice, and a second prompt message "Preset parameter performance is abnormal, do you want to update it?" can also be output by voice.

[0066] In one exemplary embodiment, the method further includes: in response to the mirror caching system being normal, controlling a preset performance parameter to remain unchanged; and determining a first preset threshold, a second preset threshold, and a third preset threshold based on the preset performance parameter.

[0067] In one optional embodiment, when the image caching system is normal, embedded C1 and D1 can be kept unchanged; and, a first preset threshold, a second preset threshold, and a third preset threshold can be determined through C1 and D1.

[0068] In one exemplary embodiment, the method further includes: in response to a first real-time performance being less than a first preset threshold, outputting a fourth alarm message and a third prompt message, wherein the fourth alarm message is used to characterize an abnormal working mode of the image caching system, and the third prompt message is used to prompt whether to control the image caching system to switch to a second working mode.

[0069] The aforementioned fourth alarm information can be any one or more, and can be output through voice, text, images, video, etc., to warn of abnormalities in the working mode of the image caching system; the aforementioned third prompt information can be any one or more, and can be output through voice, text, images, video, etc., to prompt for switching the working mode.

[0070] In one optional embodiment, in response to the first real-time performance being less than a first preset threshold, a fourth warning message “The working mode of the mirror caching system is abnormal, please handle it in time” can be output by voice, and at the same time, a third prompt message “The working mode of the mirror caching system is abnormal, do you want to switch working modes” can also be output by voice.

The local control cache module is connected to the control cache module, and the local control cache mirror synchronization optimization management module is connected to the control cache mirror synchronization optimization management module, for data synchronization.

[0074] This application dynamically manages the local control cache module, local control CPU module, local control disk array module, peer control cache module, peer control CPU module, and peer control disk array module through the CMSO management module. Especially in the high-reliability mode, cache mirror synchronization optimization is carried out through various measures such as abnormal scenario warnings, ensuring that the storage can always stably carry the front-end services, thereby improving the availability of the entire machine system. The functions of each module are as follows:

[0075] Cache Mirror Synchronization Optimization Management Module (hereinafter referred to as CMSO for cache mirror synchronization optimization): This module is located on the board and mainly uses programmable logic devices such as processors (Advanced RISC Machine, ARM). The CMSO management module can dynamically manage the local control cache module, local control CPU module, local control disk array module, peer control cache module, peer control CPU module, and peer control disk array module. Specifically, CMSO can obtain the real-time performance (throughput (Input / Output Per Second, IOPS) / bandwidth / latency) A of mirror cache synchronization under the current service model (large / small blocks, read / write, sequential / random) through the CPU module and cache module, and can obtain the real-time performance B when the dirty data in the cache is flushed to disk; at the same time, CMSO embeds the theoretical performance C1 of mirror cache synchronization and the theoretical performance D1 when the dirty data in the cache is flushed to disk under various service models. The CMSO module will perform periodic simulation tests (Simulation Test, ST) through the CPU module, cache module, and disk array module. The detailed steps are as follows:

[0076] Every time period T1 (for example, it can be 15 days), when the front-end pressure is less than the percentage E1 (for example, it can be 20%), CMSO conducts a round of simulation pressure tests with a duration of T2 (for example, it can be 30 minutes), and obtains the real-time performance C2 of mirror cache synchronization and the real-time performance D2 when the dirty data in the cache is flushed to disk under various service models. If |(C2 - C1) / C1| < F (for example, it can be 15%), the embedded C1 data is maintained; if |(D2 - D1) / D1| < H (for example, it can be 10%), the embedded D1 data is maintained; if either of the above two is not satisfied, two more rounds of ST are performed. If the results of the three STs are consistent and all are not satisfied, a system-level warning is reported, prompting to update the embedded database.

[0077] In the real business scenario:

[0078] In the normal mode, if CMSO detects that A is less than C1 * M1 (for example, it can be 75%), a system-level secondary warning is reported and it is prompted whether to switch to the high-reliability mode.

[0079] In high-reliability mode, if CMSO detects that A is less than C1*M2 (e.g., 80%), it reports a level 3 warning to the system, and simultaneously limits the maximum percentage of front-end pressure to E2 (e.g., 85%). If CMSO detects that B is less than D1*M3 (e.g., 90%), it reports a level 4 warning to the system, and suggests replacing the system disk. C1, D1, T1, T2, M1, M2, M3, E1, E2, F, and H are all system preset parameters that can be adjusted in the system or via serial port modules. The CMSO management module dynamically manages the local controller cache module, local controller CPU module, local controller disk array module, peer controller cache module, peer controller CPU module, and peer controller disk array module. Especially in high-reliability mode, various measures, such as abnormal scenario warnings, are used to optimize cache mirror synchronization, ensuring that the storage can consistently and stably support front-end services, thereby improving the overall system availability.

[0080] CPU Module: This module resides on the storage and is used to support the storage system. It provides real-time performance data for each business model to the CMSO.

[0081] Cache Module: This module is located on the board and typically contains memory and high-speed caches for various components, controlled by the CMSO module. Cache modules communicate with each other via a non-transparent bridge (NTB) or a high-speed serializer / deserializer (SerDes) link using a network protocol (RDMA OverConverged Ethernrt, RoCE) defined in the InfiniBand Trade Association (IBTA) standard.

[0082] Disk Array Module: This module is generally a non-volatile storage array such as a traditional hard disk drive (HDD), solid state drive (SSD), or non-volatile memory host controller interface specification (NVME). It is controlled by CMSO and feeds back real-time data on dirty data write performance to CMSO.

[0083] Indicator Module: This module is located on the board and is directly controlled by the serial port module. It indicates the real-time status of the current CMSO.

[0084] Wireless module: It can convert the serial port module signal into wireless signals such as Wireless Fidelity (WIFI), so that the external side can communicate with the CMSO management module without the need for a physical serial cable.

[0085] Serial port module: The serial port module enables information exchange, parameter preset, and activation of related functions between the external environment and the CMSO management module.
