Its core principle is to leverage the operating system's memory paging mechanism to use external storage space as a swap area, temporarily storing inactive data when physical memory is insufficient, thereby indirectly increasing available memory capacity. Its actual performance is limited by the interface bandwidth and storage device speed, making it suitable only for non-real-time tasks and not a substitute for physical memory upgrades. This solution primarily serves devices where memory expansion is not possible and requires a high-speed hard drive and system virtual memory configuration, but this often results in data loss during power outages.

[0026] External memory expansion technology is a hardware solution that temporarily expands external storage devices into virtual memory via a high-speed interface. Its core principle is to leverage the operating system's memory paging mechanism to use the external storage space as a swap area, temporarily storing inactive data when physical memory is insufficient, thereby indirectly increasing available memory capacity. Its actual performance is limited by the interface bandwidth and storage device speed, making it suitable only for non-real-time tasks and not a replacement for physical memory upgrades. This solution primarily serves devices that cannot have expandable memory and requires a high-speed hard drive and system virtual memory configuration, but it often suffers from data loss during power outages. In related art, current external memory expansion systems include a remote direct memory access (RDMA) module and a memory module. The RDMA module receives RDMA messages from the server and determines the corresponding memory module storage unit, thereby serving as server memory expansion. However, this method of storing server memory data by having the RDMA module receive RDMA messages from the server, determine the corresponding memory module storage unit, and thus fail to protect memory data in the event of a sudden power outage.

[0067] In addition, after "verifying each allocated disk data" in step S203, steps a to e are also included:

[0068] Step a: If any allocated disk data fails verification, it is determined whether the allocated disk data can be modified normally.

[0069] Step b: If it is determined that the allocated disk data can be modified normally, the allocated disk data is corrected by using the built-in disk error correction mechanism and / or the built-in redundancy check algorithm to obtain corrected disk data.

The memory data transmission method according to claim 7, characterized in that: After determining the data type corresponding to each original data segment from a plurality of preset data types corresponding to the last two bits of information, the method further includes: distinguishing a plurality of different data types from the data types corresponding to the original data segments; Determining whether the number of the multiple different data types is greater than a preset threshold; If it is determined that the number of the multiple different data types is greater than the preset threshold, calculating the weight of each original data segment according to a second preset period; determining one or more target original data segments from the original data segments according to the weights corresponding to the original data segments; Determine the data size corresponding to each target original data segment; Determine the data type corresponding to each target raw data segment.

9. The memory data transmission method according to claim 8, characterized in that: If it is determined that the number of the multiple different data types is greater than the preset threshold, calculating the weight of each original data segment according to a second preset period includes: If it is determined that the number of the multiple different data types is greater than the preset threshold, obtaining the data type and data interval corresponding to any original data segment; Determining one or more first original data segments belonging to the data type from the original data segments; Calculating a first weight value of the original data segment according to the number of the one or more first original data segments and the total number of data types; Determining one or more second original data segments belonging to the data interval from the original data segments; Calculating a second weight value of the original data segment according to the number of the one or more second original data segments and the total number of data intervals; determining a weight of the original data segment according to the first weight value and the second weight value; The weight corresponding to each original data segment is determined according to the second preset period.

10. The memory data transmission method according to claim 5, characterized in that: After verifying the allocated disk data, the method further includes: If any allocated disk data fails verification, determining whether the allocated disk data can be modified normally; If it is determined that the allocated disk data can be modified normally, the allocated disk data is corrected by using the error correction mechanism and / or the built-in redundancy check algorithm of the built-in disk to obtain corrected disk data; If it is determined that the allocated disk data cannot be modified normally, obtaining a corresponding address identifier from the allocated disk data; Determining a storage location of the corresponding original data segment in the server unit according to the address identifier; When the original data segment at the storage location is transferred to the built-in disk again, the allocated disk data is deleted, and address identification processing is performed on the original data segment to obtain identified disk data.
