| description | The embodiment of the invention discloses a data storage method, device and system. According to the embodiment of the invention, a data writing request is received, at least one data logic block is determined according to the data writing request, at least one data fragment corresponding to each data logic block is determined, and data corresponding to each data fragment is copied to at least one corresponding data storage block. And storing each data storage block into a data storage space, and updating meta-information. Therefore, when any storage service supported by the data storage system is adopted to write data, the data can be written into the data storage block in the data file, and the meta-information of the corresponding data file is updated, so that based on the fusion storage of the multiple storage interfaces, when the same data is called by different storage interfaces, the data can be written into the data storage block in the data file. Data migration and copying do not need to be carried o |
