The application relates to an access method and device of a distributed storage system. The access method of the distributed storage system is characterized in that the method includes: receiving a data input/output request of a virtual machine and a configuration file of the virtual machine, the data input/output request including storage location information on the virtual machine, and the configuration file including storage system information corresponding to the storage location on the virtual machine; and according to the configuration file, accessing the data input/output request to a storage system corresponding to the storage location information on the virtual machine through an interface corresponding to the storage system. Thus access of a distributed storage system can be completed under a user mode without using kernel device drive, thereby preventing inflexibility of kernel device drive, and reducing expenditure on switching between a kernel mode and the user mode by the I/O request. In addition, access of various storage systems can be supported easily, rapidly and conveniently. |
