摘要： A transaction processing method, an apparatus, and a computer system are provided. According to the method, after receiving a transaction processing request, status information of the transaction is recorded in a non-volatile memory, where the transaction processing request carries transaction data of a transaction, where the status information of the transaction includes a transaction status, a transaction identifier, and an address, and where the transaction status is an uncommitted state. The transaction data is written to the non-volatile memory according to the address. Then, the transaction status of the transaction is modified to a committed state according to the transaction identifier. Further, after writing the transaction data to an external memory of the computer system from the non-volatile memory, the transaction status of the transaction is modified to a backup state according to the transaction identifier. A transaction data processing speed can be increased in the foregoing manner.

摘要： A storage space management method and apparatus, where the method and apparatus are applied to a non-volatile memory (NVM). In a feature set that includes M image features of M idle blocks in storage space of the NVM, an idle block whose image feature is highly similar to an image feature of data to be written into the NVM is determined such that the data is written into the idle block. In this way, wear and energy consumption problems are considered during storage space allocation, and a write operation of an idle block in storage space of an NVM can consume less energy, thereby extending a life span of the NVM and reducing write operation energy consumption.

摘要： A file access method, a system, and a host are provided. According to the method, after obtaining information about first virtual space of a target file, a host allocates, in local virtual address space of the host, second virtual space to the target file, where the first virtual space is space allocated in global virtual address space by a management node in a distributed storage system to the target file. The host converts, according to a correspondence between the first virtual space and the second virtual space, a second access request of accessing the second virtual space into a first access request, where an address of the first virtual space in the first access request includes device information of a first storage node. Then, the host sends the first access request to a network device to route the first access request to the first storage node.

摘要： A file management method and a file system are applied to the field of data processing technologies. The file system monitors input/output (IO) access information for operating a file, then determines an IO access mode of the file, determines a corresponding file management policy according to the IO access mode, and finally, when the obtained file management policy is inconsistent with a current management manner of the file, adjusts, according to the determined file management policy, the current management manner of the file, for example, a storage medium and a file management granularity, so as to dynamically adjust the storage medium and the file management granularity of the file according to the IO access mode of the file.

摘要： An access request processing method is performed by a computer device that includes a processor, a dynamic random-access memory (DRAM), and a non-volatile memory (NVM). When receiving a write request, the processor may identify an object cache page according to the write request. The processor obtains the to-be-written data from a buffer according to a buffer pointer in the write request, the to-be-written data including a new data chunk to be written into the object cache page. The processor then inserts a new data node into a log chain of the object cache page, where the NVM stores data representing the log chain of the object cache page. The new data node includes information regarding the new data chunk of the object cache page. The computer device provided in this application can reduce system overheads while protecting data consistency.
