Abstract: A methods and device for accessing virtual machine (VM) data are described. A computing device for accessing virtual machine comprises an access request process module, a data transfer proxy module and a virtual disk. The access request process module receives a data access request sent by a VM and adds the data access request to a request array. The data transfer proxy module obtains the data access request from the request array, maps the obtained data access request to a corresponding virtual storage unit, and maps the virtual storage unit to a corresponding physical storage unit of a distributed storage system. A corresponding data access operation may be performed based on a type of the data access request.

Abstract: A server receives a request to upload a file form a user device. The server may generate a unique file ID associated with the file based on the request, and transmit the file ID to the user device. The user device may divide the file to generate multiple slice files and their corresponding slice IDs. From the user device, the server receives the multiple slice files and the slice IDs. Based on the slice IDs, the server may determine storage addresses at which to store the multiple slice files in a distributed storage system using a consistent hash algorithm. The multiple slice files may be stored based on the corresponding storage addresses of the distrusted storage system.
