[0029] In order to make the purpose, technical scheme and advantages of the present invention clearer, the technical scheme of the present invention will be clearly and completely described through the implementation method with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. In the following embodiments, optional features and examples are provided in each embodiment at the same time. The various features recorded in the embodiments can be combined to form multiple optional schemes, and each numbered embodiment should not be regarded as only one technical scheme. The acquisition, storage, use, processing, etc. of data in the technical scheme of this application comply with the relevant provisions of national laws and regulations.

[0030] In the related art, there is a lack of automated capacity monitoring and management tools for ZNS NVMe SSDs under the Linux operating system. Users need to manually check and manage the capacity usage of each zone, and the capacity usage is presented through relatively low-level statements with poor readability, requiring professionals to interpret it into more readable capacity usage information. This not only increases the workload, but is also prone to errors and omissions, and it is impossible to achieve real-time monitoring, resulting in low efficiency, inaccuracy, and delay in capacity monitoring.

[0031] Figure 1 The flowchart of a solid state disk capacity monitoring method provided by an embodiment of the present invention is shown. The solid state disk capacity monitoring method provided by an embodiment of the present invention can be applied to monitoring the capacity of a ZNS NVMe SSD solid state disk under a Linux operating system. The method can be executed by a solid state disk capacity monitoring device, which is implemented in software and / or hardware, and the device can be configured in a terminal device, for example, the device can be partially configured in a terminal device that deploys an SSD, and partially configured in a server.

[0032] like Figure 1 As shown, the solid state disk capacity monitoring method provided in the embodiment of the present invention may include the following steps:

[0033] S110: Acquire original information of a unit logical area at a preset time, and determine capacity index data of the solid state disk according to the original information.

[0034] In the embodiment of the present invention, the preset time may include a time at every first preset time interval. The first preset time interval may be set according to a specific scenario, and when the first preset time interval is short, obtaining the original information of the unit logical area at the preset time may be considered as obtaining the original information of the unit logical area in real time.

[0035] The unit logical area may include an area obtained by dividing the logical address space in the solid state disk into a preset size. Figure 2 A schematic diagram of the division of the logical address space in a solid state disk in a solid state disk capacity monitoring method provided by an embodiment of the present invention is shown. Figure 2 The unit logical area Zone0-Zonex can be understood as a number of areas that are equally divided into the entire logical address space of the SSD based on the ZNS technology. Each area has an independent address space and management method, which is designed to optimize the performance and durability of the storage device.

[0036] In this embodiment, for ZNS NVMe SSD under Linux operating system, a daemon collection program can be written based on existing programming languages ​​(such as Golang language). Among them, the collection program can obtain the original information of the unit logical area in all ZNS NVMe SSDs deployed on this device by calling the function interface provided by the Linux operating system (for example, calling Linux blkzone).

[0037] The original information of the unit logical area may include, but is not limited to, the number information, identification information, and space situation information of the unit logical area contained in the solid state disk. Figure 2 In the logical address space division diagram of the solid state disk shown in FIG. 1 , the original information of the unit logical area may include the number information of the unit logical area (ie, x+1), the identification information (ie, Zone0-Zonex), and the space situation information of the unit logical area. Figure 2 Taking Zone2 in the example, the space situation information may include but is not limited to the first and last address information of the unit logical area Zone2, the first and last address information of the invalid space in the unit logical area, and the write pointer address information.

[0038] In this embodiment, the capacity index data of the solid state disk may include but is not limited to the total capacity, used capacity and free capacity of the solid state disk. Determining the capacity index data of the solid state disk based on the original information of the unit logical area may include: determining the total capacity, used capacity and free capacity of the solid state disk based on the number information, identification information and space situation information of the unit logical area in the solid state disk.

[0039] In some optional embodiments, determining the capacity index data of the solid-state disk based on the original information may include: performing preset processing on the original information to obtain sub-capacity index data of the unit logical area; wherein the preset processing may include: base conversion processing, capacity calculation processing and preset capacity unit formatting processing; and determining the capacity index data of the solid-state disk based on the sub-capacity index data.

[0040] See again Figure 2Since the space situation information in the unit logical area is usually in binary form, the total capacity and invalid space in the unit logical area can be determined respectively by performing base conversion processing and mathematical calculation processing (i.e., capacity calculation processing) on ​​the first and last address information of the unit logical area and the first and last address information of the invalid space in the unit logical area. Among them, the difference between the total capacity and the invalid space can be used as the actual capacity of the unit logical area. Since each unit logical area needs to write data in a sequential manner, the write pointer address information can also be converted, and the write pointer address after base conversion and the starting address information of the unit logical area can be calculated to determine the write amount and free capacity in the actual capacity of the unit logical area.

[0041] In addition, for the convenience of management, in this embodiment, the capacity unit (i.e., preset capacity unit) can be preset, and the determined total capacity, invalid space, actual capacity, write amount, and free capacity can be converted into the preset capacity unit to implement the preset capacity unit formatting operation. Among them, the actual capacity, write amount, and free capacity, etc. formatted into the preset capacity unit, can be included in the sub-capacity indicator data of the unit logical area.

[0042] Furthermore, by summarizing and calculating the sub-capacity index data of all unit logical areas in the solid-state disk, capacity index data such as the total capacity, used capacity and free capacity of the solid-state disk can be obtained.

[0043] In these optional implementations, by performing base conversion processing, capacity calculation processing, and preset capacity unit formatting processing on the original information of the unit logical area, the sub-capacity indicator data of the unit logical area can be determined, and then the capacity indicator data of the solid state disk can be determined based on each sub-capacity indicator data.

[0044] S120: Monitor the capacity of the solid state disk according to the capacity indicator data and the preset threshold.

[0045] In this embodiment, the capacity index data may represent the capacity usage of the solid state disk, and the preset threshold may represent the threshold of insufficient remaining capacity. The capacity of the solid state disk may be monitored by comparing the capacity index data with the preset threshold.

[0046] In some optional implementations, capacity monitoring of the solid-state disk based on capacity indicator data and preset thresholds may include: determining capacity utilization based on the capacity indicator data; and issuing a capacity alarm to the solid-state disk through a preset alarm method when the capacity utilization reaches a preset threshold.

[0047] The proportion of the used capacity to the total capacity in the capacity indicator data may be used as the capacity utilization rate of the solid state disk. The preset threshold may include an alarm threshold of the capacity utilization rate, such as 75%. The preset alarm method may include but is not limited to email notification, SMS notification, phone notification, and instant messaging software notification.

[0048] The related art lacks an alarm mechanism for ZNS NVMe SSD, which may easily lead to write failure or performance degradation due to the exhaustion of remaining capacity. In these optional implementations, when the capacity utilization rate reaches the preset threshold, the SSD alarm can be issued through the preset alarm method; when the capacity utilization rate does not reach the preset threshold, no alarm is issued. This improves the reliability and performance of the device to which the SSD belongs.

[0049] In addition, in some embodiments, when the solid-state disks include at least two, the capacity indicator data of the solid-state disks may also include a solid-state disk identifier; correspondingly, when there is a solid-state disk whose capacity utilization rate reaches a preset threshold, a capacity alarm can be issued for the corresponding solid-state disk through a preset alarm method based on the solid-state disk identifier.

[0050] In addition, in some embodiments, the preset threshold may include an alarm threshold of the remaining capacity rate, such as 15%. In this case, the capacity monitoring of the solid state disk according to the capacity indicator data and the preset threshold may also include: determining the remaining capacity rate according to the capacity indicator data; and issuing a capacity alarm to the solid state disk in a preset alarm mode when the remaining capacity rate is less than or equal to the preset threshold.

[0051] The embodiment of the present invention provides a method for monitoring the capacity of a solid-state disk, which obtains the original information of a unit logical area at a preset time, and determines the capacity index data of the solid-state disk according to the original information; wherein the unit logical area includes an area obtained by dividing the logical address space in the solid-state disk into a preset size; and the capacity of the solid-state disk is monitored according to the capacity index data and a preset threshold. By obtaining the original information of the unit logical area at each preset time, and obtaining the capacity index number of the solid-state according to the original information processing, efficient and accurate automatic monitoring of the capacity of the solid-state disk can be achieved.

[0052] The embodiments of the present invention can be combined with the solid-state disk capacity monitoring method proposed in the above embodiments. This embodiment describes the data storage aspect in detail based on the above embodiments. By storing capacity indicator data in time series, it is convenient for subsequent capacity query, trend prediction and other business executions; by storing capacity alarm log data, it is possible to locate unit logical areas and / or solid-state disks with insufficient storage space, balance the use of storage space, and reduce data writing failures; by using the rule parameters in the storage capacity monitoring process (such as preset thresholds and alarm rules, etc.), it is convenient for the normal execution of the monitoring method in situations such as cold start.

[0053] The solid-state disk capacity monitoring method provided by an embodiment of the present invention may also include: storing capacity indicator data in a time sequence corresponding to preset moments; predicting the capacity indicator data within a preset time range based on the sequentially stored capacity indicator data through a capacity trend prediction model; and storing the predicted capacity indicator data.

[0054] In this embodiment, the relevant data of SSD capacity monitoring can be stored in a preset database (such as Click house data, MySQL database, etc.) through an existing database management system with online analysis and processing and real-time data analysis functions to support real-time analysis and processing of relevant data of large-scale SSD capacity monitoring.

[0055] Among them, since the preset time has a corresponding relationship with the original information, and the original information has a corresponding relationship with the capacity index data, the preset time and the capacity index data also have a corresponding relationship. By storing the capacity index data in the preset database according to the time sequence of the corresponding preset time, it is beneficial to the execution of subsequent capacity query, trend prediction and other services.

[0056] The capacity trend prediction model may include an existing machine learning model with time series data prediction function. The historical capacity index data may be obtained as a sample set to construct and update the capacity trend prediction model. Accordingly, the capacity index data of the solid-state disk stored in time series corresponding to the solid-state disk may be predicted by the newly constructed capacity trend prediction model to predict the capacity index data of the solid-state disk within a preset time range (e.g., the next 15 days, 30 days, etc.).

[0057] The predicted capacity index data can also be stored in a preset database. By predicting the trend of capacity index data, it is not only convenient to optimize and manage the upper-layer applications of the SSD, thereby improving performance, but also provides a reference for the optimization strategy of balanced capacity usage, reduces failures caused by uneven capacity usage, and extends the service life of the SSD.

[0058] In some optional embodiments, before obtaining the original information of the unit logical area at the preset moment, it may also include: configuring and storing the preset threshold in response to a first configuration instruction of the preset threshold; wherein the stored preset threshold is updated based on each of the capacity indicator data stored in sequence.

[0059] The solid state disk capacity monitoring device may also provide a user interface (such as an interface written based on HTML), and may receive a first configuration instruction of a preset threshold through a first interface in the user interface, and may store the configured preset threshold in a preset database. In addition, if a preset threshold has been stored in the preset database, the stored preset threshold may be replaced by the newly configured preset threshold; or the newly configured preset threshold may be stored while retaining the stored preset threshold.

[0060] The solid state disk capacity monitoring device can also automatically update the stored preset threshold value based on the sequentially stored capacity indicator data in response to a preset trigger, thereby ensuring the timeliness and accuracy of the alarm. The preset trigger can be set according to the application scenario, for example, it can include every second preset time interval, or it can include the alarm frequency being less than the preset frequency, etc., which are not exhaustive here.

[0061] In some optional implementations, the solid-state disk capacity monitoring method may further include: when the result of the capacity monitoring includes a capacity alarm, storing log data of the capacity alarm; wherein the alarm rule corresponding to the capacity alarm is pre-configured and stored based on a second configuration instruction.

[0062] The results of capacity monitoring may include capacity alarm and normal capacity. The capacity alarm refers to the situation where the solid-state disk alarm is issued through the preset alarm method; the normal capacity refers to the situation where the solid-state disk alarm is not issued. By storing the log data of the capacity alarm in the preset database in the case of a capacity alarm, it is possible to locate the unit logical area and / or solid-state disk with insufficient storage space, balance the use of storage space, and reduce data writing failures.

[0063] The alarm rules corresponding to the capacity alarm may include, but are not limited to, preset alarm methods and communication accounts corresponding to the preset alarm methods. The second configuration instruction of the alarm rules may be received through the second interface in the user interface, and the configured alarm rules may be stored in the preset database. If the alarm rules are already stored in the preset database, the stored alarm rules may be replaced by the newly configured alarm rules; or the newly configured alarm rules may be stored while retaining the stored alarm rules.

[0064] By storing rule parameters such as preset thresholds and alarm rules in the capacity monitoring process in a preset database, it is beneficial to configure the preset thresholds and alarm rules in situations such as cold start, so that the monitoring method can be executed normally.

[0065] In some optional implementations, the solid state disk capacity monitoring method may further include: storing the original information and / or sub-capacity indicator data along with the corresponding capacity indicator data.

[0066] In these optional implementations, in addition to storing the capacity indicator data in a preset database in a time series, the original information and / or sub-capacity indicator data used to process the capacity indicator data can also be stored in the preset database in a time series along with the corresponding capacity indicator data. By storing the original information and / or sub-capacity indicator data, it is helpful to repair the capacity indicator data in abnormal situations such as loss or damage of the capacity indicator data, thereby improving the robustness of capacity monitoring.

[0067] In some optional embodiments, the SSD capacity monitoring method may further include: receiving a display mode and a display dimension; wherein the display mode includes at least one of the following: a SSD mode, a device mode, and a device cluster mode; the display dimension includes at least one of the following: a time interval dimension, a characteristic value dimension, and a capacity trend prediction dimension; processing the stored capacity indicator data according to the display mode and the display dimension, and visually displaying the processing results through a preset display method.

[0068] The display mode and display dimension may be received through a third interface in the user interface.

[0069] Among them, the display mode can represent the aggregation dimension of capacity indicator data. When the display mode is SSD mode, the capacity indicator data can be displayed with SSD as the aggregation dimension; when the display mode is device mode, the capacity indicator data of each SSD deployed on the device can be summarized and displayed with device as the aggregation dimension; when the display mode is device cluster mode, the capacity indicator data of each device deployed in the cluster can be summarized and displayed with device cluster as the aggregation dimension.

[0070] Among them, the display dimension can represent the data that needs to be displayed in the capacity indicator data within the aggregation dimension. Among them, when the display dimension includes the time interval dimension, the historical time interval can be set to filter and display the capacity indicator data within the historical time interval. Among them, the characteristic value of the capacity indicator data can include at least one of the following: peak value, mean value and minimum value, etc. When the display dimension includes the characteristic value dimension, the characteristic value of the capacity indicator data within the default time interval or the set historical event interval can be determined and displayed. Among them, when the display dimension includes the capacity trend prediction dimension, the capacity indicator data predicted based on the stored capacity indicator data can be displayed. In addition, the display dimension can also include the capacity alarm dimension, and when the display dimension includes the capacity alarm dimension, the capacity indicator data that triggers an alarm within the default time interval or the set historical event interval can be displayed separately.

[0071] Among them, the solid-state disk capacity monitoring device can perform relevant processing (such as screening, calculation, etc.) on the stored capacity indicator data, capacity alarm log data and predicted capacity indicator data according to the received display mode and display dimension, and can display the processed data in the fourth interface of the user interface according to preset graphics, tables or views to achieve visual display.

[0072] In these optional implementations, the stored data is processed and visualized based on the display mode and display dimension, which can more intuitively present the capacity usage of the solid state drive and improve the user experience.

[0073] The embodiment of the present invention describes the data storage in detail based on the above embodiment. By storing capacity indicator data in time series, it is convenient for subsequent capacity query, trend prediction and other business executions; by storing the log data of capacity alarm, it is possible to locate the unit logical area and / or solid-state disk with insufficient storage space, balance the use of storage space, and reduce data writing failures; by using the rule parameters in the storage capacity monitoring process, it is convenient for the normal execution of the monitoring method in situations such as cold start.
