[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with 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 of 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.

[0020] The present invention will be further described below in conjunction with the embodiments.

[0021] Example: Refer to Figures 1 to 6 A data storage device and a data storage system include a storage medium body 5, the storage medium body 5 is such as a hard disk, SSD, etc., and the storage medium body 5 is an existing well-known technology.

[0022] A receiving cavity is provided at the lower side of the server cabinet body 1, and a drawer 3 is slidably connected to the receiving cavity. The drawer 3 is used to store related items for easy access.

[0023] The outside of the storage medium body 5 is also provided with a server cabinet body 1 for storing the storage medium. The lower side of the server cabinet body 1 is provided with a receiving cavity, and the receiving cavity is slidably connected with a drawer 3. The front end of the server cabinet body 1 is rotatably provided with a protective door 2, and also includes a storage cavity 4 provided in the server cabinet body 1, a placement plate 41 is fixedly connected in the storage cavity 4, and a storage medium body 5 is placed on the upper end of the placement plate 41, and the storage medium body 5 includes a data storage system 51. Specifically, the data storage system 51 is composed of a distributed data storage module 511, a data hierarchical storage module 512, a redundant backup and fault tolerance module 513, an intelligent data cache module 514, a dynamic load balancing module 515, a data query and retrieval module 516, and a data encryption and security module 517: Distributed data storage module 511, the data storage system adopts a distributed architecture, divides the data into multiple data blocks, and stores the data blocks on multiple storage nodes according to the load balancing strategy. Each node can use different types of storage media (such as hard disk, SSD, etc.), and flexibly adjust the storage strategy according to the characteristics of the storage medium, so as to achieve the optimal balance between storage performance and cost.

[0024] Data hierarchical storage module 512: To improve storage efficiency, a data tiered storage module strategy is adopted to store hot data (frequently accessed data) in faster storage media (such as SSDs), and cold data (less frequently accessed data) on traditional hard disks or cheaper storage media. The storage level of data is dynamically adjusted through intelligent algorithms to ensure high efficiency when accessing data.

[0025] Redundancy backup and fault tolerance module 513: A multi-copy redundant storage mechanism is adopted to ensure that data can be quickly restored when a storage node fails. Each data block is stored in at least two copies, and the copies are distributed on different physical nodes to prevent data loss caused by single point failures. At the same time, a fault-tolerant mechanism based on erasure coding technology is adopted to further improve data reliability and storage space utilization.

[0026] Intelligent data cache module 514: The system introduces an intelligent caching mechanism to cache data with high access frequency in high-speed cache (such as memory, NVMeSSD, etc.) to reduce frequent access to the underlying storage. The intelligent cache management system can dynamically adjust the cache strategy according to the data access pattern, thereby improving the response speed and throughput of data access.

[0027] Dynamic load balancing module 515: The system implements a dynamic load balancing module mechanism, which dynamically adjusts the data distribution method according to the load conditions, storage capacity and performance indicators of each storage node. Through this mechanism, data access bottlenecks can be avoided to the greatest extent in a large-scale data storage environment, ensuring the efficient operation of the entire system.

[0028] Data query and retrieval module 516: The data storage system is equipped with an efficient data retrieval engine, which can quickly locate and access required information in massive data through indexing technology and distributed query optimization algorithms. The retrieval engine supports multiple data query methods, such as exact matching, fuzzy matching and range query.

[0029] Data Encryption and Security Module 517: To ensure the security of data, the system uses strong encryption technology (such as AES, RSA, etc.) during storage and transmission to ensure the confidentiality and integrity of data. In addition, the system also provides security management functions such as permission management and audit logs to prevent data leakage and illegal access.

[0030] The server cabinet body 1 is prevented from being placed at the upper end of the plate 41. The inner wall of the server cabinet body 1 is provided with multiple heat dissipation components. Specifically, the heat dissipation component includes a heat dissipation fan fixedly embedded and installed on the inner wall of the server cabinet body 1. A heat dissipation port 6 corresponding to the horizontal position of the heat dissipation fan is provided on another inner wall of the server cabinet body 1. A dustproof net 7 is provided on the outer side of the heat dissipation port 6. The side wall of the server cabinet body 1 is also provided with a groove 8 and a sliding cavity 9 connected to the heat dissipation port 6. The sliding cavity 9 is slidably connected with a baffle 10. When the temperature inside the server cabinet body 1 is within a normal range, the baffle 10 blocks the heat dissipation port 6 to ensure the safety of the environment inside the server cabinet body 1, and can also prevent dust from blowing into the server cabinet body 1 from the heat dissipation port 6, thereby protecting the storage medium body 5 in the server cabinet body 1.

[0031] A guide groove 81 connected to the lower side of the groove 8 is provided on the side wall of the server cabinet body 1. A plurality of guide wheels 101 are rotatably mounted on the lower end of the baffle 10 through a mounting plate. The guide wheels 101 are movably matched with the guide groove 81. Rolling friction replaces sliding friction, thereby reducing the moving friction of the baffle 10.

[0032] The width of the guide groove 81 is smaller than the width of the groove 8 , thereby ensuring the stability of the movement of the guide wheel 101 .

[0033] A plurality of return springs 11 are fixedly connected between the baffle 10 and the groove 8 , and a proximity sensor 12 is fixedly embedded and installed on the side wall of the server cabinet body 1 at a side of the groove 8 away from the sliding cavity 9 . The proximity sensor 12 is used to monitor the position of the baffle 10 in real time.

[0034] The proximity sensor 12 signal is connected to a controller, and the controller is electrically connected to the cooling fan. When the baffle 10 moves close to the proximity sensor 12, the controller controls the cooling fan to start, dissipate heat for the server cabinet body 1, and ensure the safety of the environment inside the storage medium body 5.

[0035] The side wall of the server cabinet body 1 is provided with a mounting groove 13 above the heat dissipation port 6, and a movable groove 15 is provided between the mounting groove 13 and the groove 8. A movable rod 16 is fixedly connected to the upper end of the baffle 10, and a control component 14 for driving the movable rod 16 to move is provided in the mounting groove 13. Specifically, the control component 14 includes a sealing cylinder 141 fixedly connected in the mounting groove 13, and a filling cavity 142 is provided in the sealing cylinder 141. The filling cavity 142 is filled with an expansion liquid. The expansion liquid expands when heated and contracts when cooled. This phenomenon is because the movement of particles (atoms or molecules) in an object changes with temperature. When the temperature rises, the vibration amplitude of the particles increases, causing the object to expand; but when the temperature drops, the vibration amplitude of the particles decreases, causing the object to contract. ‌ The filling chamber 142 is limitedly and slidably connected with a piston plate 143, and the piston plate 143 is fixedly connected with a sliding rod 144. The other end of the sliding rod 144 is fixedly connected with a push plate 145, and the push plate 145 is arranged in abutment with the movable rod 16. When the storage medium body 5 is working, heat is generated, which causes the temperature inside the server cabinet body 1 to continue to rise, so that the expansion fluid in the filling chamber 142 expands, and the volume increases, driving the piston plate 143 to move toward the direction of the proximity sensor 12, driving the sliding rod 144 and the push plate 145 to move toward the direction of the proximity sensor 12, and the push plate 145 pushes the movable rod 16, driving the baffle 10 to move toward the direction of the proximity sensor 12. The higher the temperature, the larger the volume of the expansion fluid. When the baffle 10 approaches the proximity sensor 12, it means that the temperature inside the server cabinet body 1 is difficult to cool down the temperature inside the server cabinet body 1 through the heat dissipation port 6. The controller controls the heat dissipation fan to start to dissipate heat from the server cabinet body 1, thereby achieving the purpose of rapid cooling, and further ensuring the safety of the environment inside the storage medium body 5.

[0036] The specific use principle of the present invention is as follows: A storage medium body 5 such as a hard disk or SSD is placed on the upper end of the placement plate 41 in the server cabinet body 1. When the temperature inside the server cabinet body 1 is within a normal range, the baffle 10 blocks the heat dissipation port 6 to ensure the safety of the environment inside the server cabinet body 1 and prevent dust from entering the server cabinet body 1 from the heat dissipation port 6, thereby protecting the storage medium body 5 in the server cabinet body 1. The storage medium body 5 will generate heat when working, causing the temperature inside the server cabinet body 1 to continue to rise, causing the expansion fluid in the filling chamber 142 to expand. By increasing its volume, it drives the piston plate 143 to move toward the proximity sensor 12, driving the sliding rod 144 and the push plate 145 to move toward the proximity sensor 12. The push plate 145 pushes the movable rod 16, driving the baffle 10 to move toward the proximity sensor 12. The higher the temperature, the larger the volume of the expansion fluid. When the baffle 10 is close to the proximity sensor 12, it means that the temperature inside the server cabinet body 1 is difficult to cool down through the heat dissipation port 6. The controller controls the heat dissipation fan to start and dissipate heat from the server cabinet body 1, thereby achieving the purpose of rapid cooling and further ensuring the safety of the environment inside the storage medium body 5.

[0037] When storing data, the data storage system 51 first divides the data into multiple data blocks according to a predetermined size, and then distributes these data blocks to different storage nodes according to the load balancing strategy. During the distribution process, factors such as the storage capacity, performance and network bandwidth of the node are considered to ensure balanced distribution of data; the system will regularly analyze the frequency of data access and use algorithms such as LRU (Least Recently Used) or LFU (Least Frequently Used) to determine which data should be cached and which data should be cleared. For hot data, the system will store it in the cache to reduce access latency; copies of each data block will be distributed on different storage nodes to ensure redundant storage of data. If a node fails, the system will recover the data by reading other copies. At the same time, the erasure code technology can be used to restore complete data when only part of the copies are lost, thereby improving storage efficiency and fault tolerance; the system monitors the load of each storage node. When the load of a node exceeds the predetermined threshold, the system will automatically migrate part of the data to other nodes to achieve load balancing. During data migration, the system will ensure data consistency and integrity; when storing data, the system will automatically encrypt the data to ensure data security during storage and transmission. When users access data, the system will verify the user's identity according to the permission control policy to ensure that only authorized users can access the data.
