[0030] Figure 2 is a flow chart of a data storage method according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0031] Step S201, determining multiple RAID levels according to the data importance of multiple message packets in the target business and the performance requirement level of each message packet on the server, and configuring a hard disk group that meets each RAID level for the server, the performance requirement level includes: the requirement level of the read and write rate and the requirement level of the delay rate, the server is used to execute the target business, and one hard disk group includes at least one hard disk;

[0032] Specifically, the RAID level corresponds to the hard disk group one by one, and multiple RAID levels constitute the RAID array of the target business. The target business refers to a specific business or application scenario that requires data storage. To configure the hard disk group, the appropriate hard disk type, capacity and quantity must be selected according to the requirements of the RAID level, and the hard disks must be physically connected and logically configured.

[0033] Specifically, the performance requirement levels include a first level, a second level and a third level, and the levels of the performance requirements represented by the first level, the second level and the third level decrease in sequence.

[0034] Step S202, when the server receives a target message packet sent by the device, determining a security level indicator according to the data importance, data access frequency and data recovery time target of the target message packet, wherein the security level indicator is an indicator for evaluating the security level required for the message packet, and the target message packet is a part of a plurality of the message packets;

[0035] Specifically, the target message packet refers to a specific data unit sent from the device to the server, and the security level index is calculated based on data importance, data access frequency, and data recovery time target to evaluate the security level required for the target message packet. Different security levels correspond to different RAID levels.

[0036] Step S203, according to the security level index, determine the target RAID level from the multiple RAID levels, and determine the hard disk group corresponding to the target RAID level as the target hard disk group, and use the target hard disk group to store the target message packet, the target RAID level is one of the multiple RAID levels.

[0037] Specifically, according to the security level index, a target RAID level is determined from a plurality of RAID levels, a hard disk group corresponding to the target RAID level is determined, and the corresponding hard disk group is used to store the target message packet.

[0038] Through the embodiment, firstly, according to the data importance of multiple message packets in the target business and the performance requirements such as the read and write rate and delay rate of the server, multiple RAID levels are determined, and then the corresponding hard disk group is configured for the server according to the determined multiple RAID levels. When the target message packet sent by the device is received, the security level index of the target message packet is determined according to the data importance, data access frequency and data recovery time target of the target message packet. Finally, according to the security level index, the target RAID level is determined from multiple RAID levels, and the hard disk group corresponding to the target RAID level is determined as the target hard disk group, and the hard disk group is used to store the target message packet. The present application dynamically selects the RAID level according to the characteristics and requirements of the data, realizes the reasonable configuration of the hard disk resources, ensures the full utilization of the server hard disk space, avoids the waste and uneven use of the hard disk space, and improves the utilization rate and efficiency of the hard disk resources.

[0039] In an optional solution, the data importance of the message packet includes a first degree, a second degree and a third degree, and the importance represented by the first degree, the second degree and the third degree decreases in sequence. After configuring a hard disk group that meets each of the RAID levels for the server, the method further includes:

[0040] Step S204: determining the backup strategy and backup frequency of the RAID level corresponding to each message packet according to the data importance of the plurality of message packets, wherein the backup strategy includes: adopting full backup when the data importance of the message packet is the first degree, adopting incremental backup when the data importance of the message packet is the second degree, and adopting differential backup when the data importance of the message packet is the third degree;

[0041] Specifically, multiple RAID levels are determined according to the data importance of multiple message packets in the target business and the performance requirement level of each message packet to the server, including: when the data importance of the message packet is the first level and the performance requirement level is the first level, determining that the multiple RAID levels include RAID10; when the data importance of the message packet is the first level and the performance requirement level is the second level, determining that the multiple RAID levels include RAID1; when the data importance of the message packet is the first level and the performance requirement level is the third level, determining that the multiple RAID levels include RAID6; when the data importance of the message packet is the second level and the performance requirement level is the first level, determining that the multiple RAID levels include RAID5; and when the data importance of the message packet is the second level and the performance requirement level is the first level, determining that the multiple RAID levels include RAID6. When the importance of the data of the message packet is the second level and the performance requirement level is the second level, it is determined that the multiple RAID levels include RAID5 or RAID6; when the importance of the data of the message packet is the second level and the performance requirement level is the third level, it is determined that the multiple RAID levels include RAID0; when the importance of the data of the message packet is the third level and the performance requirement level is the first level, it is determined that the multiple RAID levels include RAID0; when the importance of the data of the message packet is the third level and the performance requirement level is the second level, it is determined that the multiple RAID levels include RAID0 or RAID1; when the importance of the data of the message packet is the third level and the performance requirement level is the third level, it is determined that the multiple RAID levels include RAID0.

[0042] Specifically, for message packets with high data importance and high performance requirements, RAID10 can provide data redundancy and high performance; for message packets with high data importance and medium performance requirements, RAID1 can provide data redundancy at a lower cost; for message packets with high data importance and low performance requirements, RAID6 can provide data redundancy and high fault tolerance, but poor write performance; for message packets with medium data importance and high performance requirements, RAID5 can provide data redundancy and better performance; for message packets with medium data importance and medium performance requirements, RAID5 or RAID6 can be selected according to specific needs, among which RAID6 provides higher fault tolerance; for message packets with medium data importance and low performance requirements, RAID0 can improve performance but does not provide data redundancy, and is suitable for non-critical data; for message packets with low data importance and high performance requirements, RAID0 can improve performance, and is suitable for scenarios with extremely high performance requirements but low data security requirements; for message packets with low data importance and medium performance requirements, RAID 0 or RAID 6 can be selected according to specific needs 1, where RAID1 provides data redundancy but at a higher cost; for message packets with low data importance and low performance requirements, RAID0 can improve performance and reduce costs, and is suitable for non-core business data.

[0043] Specifically, full backup refers to a complete backup of data at regular intervals, incremental backup refers to backing up only the data that has changed since the last backup, and differential backup refers to backing up all data that has changed since the last full backup. The backup frequency and strategy can be adjusted according to the target business and data importance.

[0044] Step S205: setting backup parameters of multiple RAID levels according to the backup strategy and the backup frequency.

[0045] Specifically, the backup parameters that are set include: according to the backup strategy, the backup frequency and the backup window (ie, the time period for performing the backup operation).

[0046] Specifically, for data with lower importance, a lower backup frequency or incremental backup or differential backup is used. These backup methods only back up data that has changed since the last backup, reducing the redundancy of backup data, thereby reducing the occupation of system resources and improving overall performance; for data with higher importance, a higher backup frequency or full backup is used, which means that each backup will contain a complete data set, thereby ensuring that key data is backed up more frequently and comprehensively, improving data security. Using different backup frequencies and strategies for data of different importance can avoid unnecessary frequent backups and redundant storage, make reasonable use of the storage space of the hard disk, and further solve the problem of unreasonable hard disk resource allocation in the prior art.

[0047] In the described embodiment, different backup strategies are adopted according to the different data importance levels of message packets, so that differentiated backup of different RAID levels can be achieved, further ensuring that the determined backup strategy and backup frequency match the message packets of different data importance, thereby further realizing the rational application of hard disk resources.

[0048] In some other exemplary embodiments, the security level index is determined according to the data importance, data access frequency and data recovery time target of the target message packet, including:

[0049] According to the first corresponding relationship, determining the first score as the score corresponding to the importance degree range of the data importance of the target message packet, wherein the first corresponding relationship is the corresponding relationship between the importance degree range and the score;

[0050] According to the second corresponding relationship, determining the second score as the score corresponding to the frequency range where the data access frequency of the target message packet is located, wherein the second corresponding relationship is a corresponding relationship between the frequency range and the score;

[0051] According to the third corresponding relationship, determine that the third score is the score corresponding to the time range where the data recovery time target of the target message packet is located, and the third corresponding relationship is the corresponding relationship between the time range and the score;

[0052] The security level indicator is determined to be the sum of the first score, the second score and the third score.

[0053] Specifically, the first corresponding relationship, the second corresponding relationship, and the third corresponding relationship are pre-set corresponding relationships, and the importance degree range, the frequency range, and the time range are pre-set ranges.

[0054] In the described embodiment, by comprehensively considering and scoring the data importance, data access frequency and data recovery time target of the target message package, the data security level index can be evaluated more accurately, and different RAID levels can be selected for backup based on the determined security level index, thereby further achieving targeted storage of the target message package, further ensuring that the backup strategy of the target message package meets the security requirements of the target message package, and further ensuring the security and reliability of the target message package in the event of a system failure.

[0055] In addition, the present application also presets a correspondence relationship between the security level indicator and the RAID level (hereinafter referred to as the fourth correspondence relationship). After obtaining the security level indicator of the target message packet, the RAID level corresponding to the security level indicator is searched in the fourth correspondence relationship, and the RAID level is the target RAID level. The hard disk group corresponding to the target RAID level is the target hard disk group.

[0056] Exemplarily, for the settings of the first correspondence, the second correspondence, and the third correspondence, in this application, for data with high importance, that is, data that is critical to the business and whose loss or damage will cause significant losses, the threshold is set to 9-10 points; for data with medium importance, that is, data that has a certain impact on the business but is non-critical, the threshold is set to 5-8 points; for data with low importance, that is, data that has little impact on the business and whose loss or damage will not cause serious consequences, the threshold is set to 1-4 points; for data with high access frequency, that is, the number of visits per day is greater than or equal to 1,000 times, the threshold is set to 10 points. The threshold is set to 9-10 points; for medium access frequency, that is, the number of accesses per day is greater than 100 times and less than 1000 times, the threshold is set to 5-8 points; for low access frequency, that is, the number of accesses per day is less than 100 times, the threshold is set to 1-4 points; for low recovery time objectives, that is, the recovery time objectives are less than or equal to 1 hour, the threshold is set to 9-10 points; for medium recovery time objectives, that is, the recovery time objectives are greater than one hour and less than 12 hours, the threshold is set to 5-8 points; for low recovery time objectives, that is, the recovery time objectives are greater than or equal to 12 hours, the threshold is set to 1-4 points. According to the actual situation of the data, score each factor, including data importance, access frequency and recovery time objectives, and add the scores of each factor to get the total score, and select the RAID level according to the total score. Total score: 24-30 points: select RAID 10 or RAID 1 to ensure high data redundancy and high performance; total score: 15-23 points: select RAID 5 or RAID 6 to balance performance, redundancy and cost; total score: 6-14 points: select RAID 0 to reduce cost and improve performance, but it needs to be combined with a good backup strategy. By comprehensively considering and scoring the data importance, data access frequency and data recovery time goals of the target message package, the data security level index can be more accurately evaluated. By selecting different RAID levels for backup based on the determined security level index, the target message package can be stored in a targeted manner, further ensuring that the backup strategy of the target message package meets the security requirements of the target message package, and further ensuring the security and reliability of the target message package in the event of a system failure.

[0057] In another optional solution, configuring a hard disk group that meets each of the RAID levels for the server includes: configuring hard disks of a quantity and capacity corresponding to each of the RAID levels for the server according to the multiple RAID levels.

[0058] In the embodiment, by configuring hard disks with the number and capacity corresponding to each RAID level for the server, each RAID level is reasonably configured, thereby further optimizing the configuration of hard disk resources.

[0059] In another optional solution, after configuring the hard disk group that meets each of the RAID levels for the server, the method further includes: deploying a RAID controller on the server and configuring parameters of the RAID controller, the parameters of the RAID controller including at least one of the following: stripe size, verification mode;

[0060] Specifically, the average file size should be considered when configuring the stripe size. If large files such as videos and database files are mainly processed, a larger stripe size should be selected. If small files such as documents and pictures are processed, a smaller stripe size should be selected. Common verification methods include parity check, cyclic redundancy check, B+ check, etc.

[0061] The key data on the server is mounted on the RAID, wherein the key data includes at least one of the following: a database and a log file.

[0062] Specifically, mounting involves the following steps: confirming that the RAID has been correctly configured and is in an available state, creating a file system on the RAID, creating a mount point, mounting the RAID, verifying that the RAID has been successfully mounted, etc.

[0063] In the embodiment, by deploying a RAID controller on the server side and configuring stripe size parameters, the size of the blocks into which the data is divided is determined. A reasonable stripe size can optimize the use of storage space while ensuring the performance of the RAID controller. By configuring the verification method of the RAID controller, the RAID controller can detect and correct errors in the data, thereby ensuring the integrity and reliability of the data. The key data on the server is mounted on the RAID, thereby ensuring that the data is synchronized to the RAID in real time while being written to the main server.

[0064] In some further exemplary solutions of the present application, before determining the security level indicator according to the data importance, data access frequency and data recovery time target of the target message packet, the method further includes:

[0065] Decoding the message packet to obtain JSON object data in a string format;

[0066] Parsing the JSON object data to obtain key value information in the JSON object;

[0067] The key-value information is subjected to data verification, and the data verification includes: data integrity verification, data format verification, data content verification and data security verification. The data content verification includes: verifying whether the ID of the key-value information comes from a legitimate device, whether the key-value information is within a preset range, and whether the update time of the key-value information is within a preset time period.

[0068] Specifically, the message packet is subjected to data decoding and data parsing, and the processing result is subjected to data verification.

[0069] In the embodiment, the server ensures that the data can be correctly identified by decoding and parsing the data, which helps the server to accurately understand the data content sent by the device end and provide an accurate information basis for subsequent data processing; through data integrity verification, it checks whether the decoded and parsed data contains all the necessary fields, and compares the hash value of the JSON object with the expected hash value to ensure that the data has not been tampered with or lost during transmission; through data format verification, it helps to prevent data processing errors caused by format errors; through data content verification, it helps to prevent illegal devices from sending data or devices from sending abnormal data, thereby maintaining the security and stability of the system; through data security verification, it ensures that only legal devices can send messages, prevents data from being eavesdropped and tampered with during transmission, protects information from being leaked, and maintains data security. By decoding, parsing and verifying the data, the type and characteristics of the data can be more accurately identified, making the scoring of the message package more accurate, thereby making the security level index of the message package more accurate, and further optimizing the configuration of hard disk resources.

[0070] For example, taking the target message packet as the status update message of the smart bulb as an example, the specific process of data decoding, data parsing and data verification described in this application is described as follows: the server receives the status update message from the smart bulb through the MQTTBroker, the message format is JSON, including the ID, current brightness, color temperature and other information of the bulb; the server parses the payload part in the MQTT message and converts it from binary format to a JSON object in string format; extracts the bulb ID (bulb_id), current brightness (brightness) and color temperature (color_temp) and other fields from the JSON object. Convert the values ​​of these fields to appropriate types, such as converting the brightness from a string to an integer; check whether the brightness value is within the valid range (for example, 0-255), check whether the color temperature value is within the valid range (for example, 1500K-9000K, but the specific range may vary depending on the bulb model), if an invalid value is found, replace it with a default value or record an error log; store the parsed and cleaned data in the database. The database table contains fields such as bulb ID, brightness, color temperature, and update time; use transaction processing to ensure data atomicity and consistency; check whether the payload part of the MQTT message contains all necessary fields (such as bulb_id, brightness, color_temp); calculate the hash value of the JSON object and compare it with the expected hash value to verify the integrity of the data; verify whether the format of the JSON object is correct, including whether the field name is correct and whether the data type matches; use JSON Schema format verification to ensure that the message conforms to the expected format specification; verify whether the bulb ID exists in the database to ensure that the message comes from a legitimate device; check whether the brightness and color temperature values ​​are within a reasonable range to prevent the device from sending abnormal data; verify whether the update time of the message is reasonable to prevent timestamp forgery; use MQTT username and password for authentication to ensure that only legitimate devices can send messages; use TLS / SSL to encrypt MQTT connections to prevent data from being eavesdropped or tampered with during transmission; use encryption technology to protect data security when storing sensitive information (such as device keys) in the database; measure the average response time of the server to process MQTT messages to ensure that data processing is completed within a reasonable time frame; monitor the performance indicators of the database (such as query response time, write throughput, etc.) to ensure that the database can handle high concurrent requests; use stress testing tools to simulate scenarios where a large number of devices send messages at the same time to verify the performance and stability of the server.

As used below, the term "module" can implement a combination of software and / or hardware for a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceived.

[0084] The following is an introduction to the data storage device of the smart home device provided in the embodiment of the present application.

[0085] Figure 4 Schematic diagram of a data storage device for a smart home device according to an embodiment of the present application. Figure 4 As shown, the device comprises:

[0086] The first determination unit 10 is used to determine multiple RAID levels according to the data importance of multiple message packets in the target business and the performance requirement level of each message packet on the server, and configure a hard disk group that meets each RAID level for the server, the performance requirement level includes: the requirement level of the read and write rate and the requirement level of the delay rate, the server is used to execute the target business, and one hard disk group includes at least one hard disk;

[0087] Specifically, the RAID level corresponds to the hard disk group one by one, and multiple RAID levels constitute the RAID array of the target business. The target business refers to a specific business or application scenario that requires data storage. To configure the hard disk group, the appropriate hard disk type, capacity and quantity must be selected according to the requirements of the RAID level, and the hard disks must be physically connected and logically configured.

[0088] A second determining unit 20 is used to determine a security level indicator according to the data importance, data access frequency and data recovery time target of the target message packet when the server receives the target message packet sent by the device end, wherein the security level indicator is an indicator for evaluating the security level required for the message packet, and the target message packet is a part of the plurality of message packets;

[0089] Specifically, the target message packet refers to a specific data unit sent from the device to the server, and the security level index is calculated based on data importance, data access frequency, and data recovery time target to evaluate the security level required for the target message packet. Different security levels correspond to different RAID levels.

[0090] The storage unit 30 is used to determine the target RAID level from the multiple RAID levels according to the security level index, and determine the hard disk group corresponding to the target RAID level as the target hard disk group, and use the target hard disk group to store the target message packet, and the target RAID level is one of the multiple RAID levels.

[0091] Specifically, according to the security level index, a target RAID level is determined from a plurality of RAID levels, a hard disk group corresponding to the target RAID level is determined, and the corresponding hard disk group is used to store the target message packet.

[0092] Through the embodiment, the first determination unit determines multiple RAID levels according to the data importance of multiple message packets in the target business and the performance requirements such as the read and write rate and delay rate of the server, and configures the corresponding hard disk group for the server according to the determined multiple RAID levels. When the target message packet sent by the device is received, the second determination unit determines the security level index of the target message packet according to the data importance, data access frequency and data recovery time target of the target message packet, and the storage unit determines the target RAID level from multiple RAID levels according to the security level index, and determines the hard disk group corresponding to the target RAID level as the target hard disk group. The present application dynamically selects the RAID level according to the characteristics and requirements of the data, realizes the reasonable configuration of the hard disk resources, ensures the full utilization of the server hard disk space, avoids the waste and uneven use of the hard disk space, and improves the utilization rate and efficiency of the hard disk resources.

[0093] In another optional solution, the device further includes:

[0094] A third determining unit is used to determine the backup strategy and backup frequency of the RAID level corresponding to each of the message packets according to the data importance of the plurality of message packets, wherein the backup strategy includes: adopting full backup when the data importance of the message packet is the first degree, adopting incremental backup when the data importance of the message packet is the second degree, and adopting differential backup when the data importance of the message packet is the third degree;

[0095] Specifically, full backup refers to a complete backup of data at regular intervals, incremental backup refers to backing up only the data that has changed since the last backup, and differential backup refers to backing up all data that has changed since the last full backup. The backup frequency and strategy can be adjusted according to the target business and data importance.

[0096] The setting unit is used to set the backup parameters of the multiple RAID levels according to the backup strategy and the backup frequency.

[0097] Specifically, the backup parameters that are set include: according to the backup strategy, the backup frequency and the backup window (ie, the time period for performing the backup operation).

[0098] In the described embodiment, different backup strategies are adopted according to the different data importance levels of message packets, so that differentiated backup of different RAID levels can be achieved, further ensuring that the determined backup strategy and backup frequency match the message packets of different data importance, thereby further realizing the rational application of hard disk resources.

[0099] Specifically, for data with lower importance, a lower backup frequency or incremental backup or differential backup is used. These backup methods only back up data that has changed since the last backup, reducing the redundancy of backup data, thereby reducing the occupation of system resources and improving overall performance; for data with higher importance, a higher backup frequency or full backup is used, which means that each backup will contain a complete data set, thereby ensuring that key data is backed up more frequently and comprehensively, improving data security. Using different backup frequencies and strategies for data of different importance can avoid unnecessary frequent backups and redundant storage, make reasonable use of the storage space of the hard disk, and further solve the problem of unreasonable hard disk resource allocation in the prior art.

[0100] In some other exemplary embodiments, the second determining unit includes:

[0101] A first determination module, configured to determine, based on a first corresponding relationship, that a first score is a score corresponding to a range of importance of the data importance of the target message packet, wherein the first corresponding relationship is a corresponding relationship between the range of importance and the score;

[0102] A second determination module, configured to determine, according to a second corresponding relationship, that a second score is a score corresponding to a frequency range in which the data access frequency of the target message packet is located, wherein the second corresponding relationship is a corresponding relationship between the frequency range and the score;

[0103] A third determination module, configured to determine, according to a third corresponding relationship, that a third score is a score corresponding to a time range in which the data recovery time target of the target message packet is located, wherein the third corresponding relationship is a corresponding relationship between the time range and the score;

[0104] The fourth determination module is used to determine the security level indicator as the sum of the first score, the second score and the third score.

[0105] Specifically, the first corresponding relationship, the second corresponding relationship, and the third corresponding relationship are pre-set corresponding relationships, and the importance degree range, the frequency range, and the time range are pre-set ranges.

[0106] In the described embodiment, by comprehensively considering and scoring the data importance, data access frequency and data recovery time target of the target message package, the data security level index can be evaluated more accurately, and different RAID levels can be selected for backup based on the determined security level index, thereby further achieving targeted storage of the target message package, further ensuring that the backup strategy of the target message package meets the security requirements of the target message package, and further ensuring the security and reliability of the target message package in the event of a system failure.

[0107] In addition, the present application also presets a correspondence relationship between the security level indicator and the RAID level (hereinafter referred to as the fourth correspondence relationship). After obtaining the security level indicator of the target message packet, the RAID level corresponding to the security level indicator is searched in the fourth correspondence relationship, and the RAID level is the target RAID level. The hard disk group corresponding to the target RAID level is the target hard disk group.

[0108] Exemplarily, for the settings of the first correspondence, the second correspondence, and the third correspondence, in this application, for data with high importance, that is, data that is critical to the business and whose loss or damage will cause significant losses, the threshold is set to 9-10 points; for data with medium importance, that is, data that has a certain impact on the business but is non-critical, the threshold is set to 5-8 points; for data with low importance, that is, data that has little impact on the business and whose loss or damage will not cause serious consequences, the threshold is set to 1-4 points; for data with high access frequency, that is, the number of visits per day is greater than or equal to 1,000 times, the threshold is set to 10 points. The threshold is set to 9-10 points; for medium access frequency, that is, the number of accesses per day is greater than 100 times and less than 1000 times, the threshold is set to 5-8 points; for low access frequency, that is, the number of accesses per day is less than 100 times, the threshold is set to 1-4 points; for low recovery time objectives, that is, the recovery time objectives are less than or equal to 1 hour, the threshold is set to 9-10 points; for medium recovery time objectives, that is, the recovery time objectives are greater than one hour and less than 12 hours, the threshold is set to 5-8 points; for low recovery time objectives, that is, the recovery time objectives are greater than or equal to 12 hours, the threshold is set to 1-4 points. According to the actual situation of the data, score each factor, including data importance, access frequency and recovery time objectives, and add the scores of each factor to get the total score, and select the RAID level according to the total score. Total score: 24-30 points: select RAID 10 or RAID 1 to ensure high data redundancy and high performance; total score: 15-23 points: select RAID 5 or RAID 6 to balance performance, redundancy and cost; total score: 6-14 points: select RAID 0 to reduce cost and improve performance, but it needs to be combined with a good backup strategy. By comprehensively considering and scoring the data importance, data access frequency and data recovery time goals of the target message package, the data security level index can be more accurately evaluated. By selecting different RAID levels for backup based on the determined security level index, the target message package can be stored in a targeted manner, further ensuring that the backup strategy of the target message package meets the security requirements of the target message package, and further ensuring the security and reliability of the target message package in the event of a system failure.

[0109] In another optional solution, the first determination unit includes: a configuration module, which is used to configure the server with a number and capacity of hard disks corresponding to each RAID level according to the multiple RAID levels, and the device further includes: a deployment unit, which is used to deploy a RAID controller on the server and configure parameters of the RAID controller after configuring a hard disk group that meets each RAID level for the server, and the parameters of the RAID controller include at least one of the following: stripe size, verification mode;

[0110] Specifically, the average file size should be considered when configuring the stripe size. If large files such as videos and database files are mainly processed, a larger stripe size should be selected. If small files such as documents and pictures are processed, a smaller stripe size should be selected. Common verification methods include parity check, cyclic redundancy check, B+ check, etc.

[0111] The mounting unit is used to mount the key data on the server to the RAID, wherein the key data includes at least one of the following: a database and a log file.

[0112] Specifically, mounting involves the following steps: confirming that the RAID has been correctly configured and is in an available state, creating a file system on the RAID, creating a mount point, mounting the RAID, verifying that the RAID has been successfully mounted, etc.

[0113] In the embodiment, by deploying a RAID controller on the server side and configuring stripe size parameters, the size of the blocks into which the data is divided is determined. A reasonable stripe size can optimize the use of storage space while ensuring the performance of the RAID controller. By configuring the verification method of the RAID controller, the RAID controller can detect and correct errors in the data, thereby ensuring the integrity and reliability of the data. The key data on the server is mounted on the RAID, thereby ensuring that the data is synchronized to the RAID in real time while being written to the main server.

[0117] A verification unit is used to perform data verification on the key-value information, wherein the data verification includes: data integrity verification, data format verification, data content verification and data security verification, wherein the data content verification includes: verifying whether the ID of the key-value information comes from a legitimate device, whether the key-value information is within a preset range, and whether the update time of the key-value information is within a preset time period.

[0118] Specifically, the message packet is subjected to data decoding and data parsing, and the processing result is subjected to data verification.

[0119] In the embodiment, the server ensures that the data can be correctly identified by decoding and parsing the data, which helps the server to accurately understand the data content sent by the device end and provide an accurate information basis for subsequent data processing; through data integrity verification, it checks whether the decoded and parsed data contains all the necessary fields, and compares the hash value of the JSON object with the expected hash value to ensure that the data has not been tampered with or lost during transmission; through data format verification, it helps to prevent data processing errors caused by format errors; through data content verification, it helps to prevent illegal devices from sending data or devices from sending abnormal data, thereby maintaining the security and stability of the system; through data security verification, it ensures that only legal devices can send messages, prevents data from being eavesdropped and tampered with during transmission, protects information from being leaked, and maintains data security. By decoding, parsing and verifying the data, the type and characteristics of the data can be more accurately identified, making the scoring of the message package more accurate, thereby making the security level index of the message package more accurate, and further optimizing the configuration of hard disk resources.
