FILE ACCESS METHOD, DISTRIBUTED STORAGE SYSTEM AND NETWORK DEVICE

摘要

Disclosed are a file access method, distributed storage system and network device, the method comprising: a network device receives an access request transmitted by a host, the access request being used to access a first virtual space of a target file, the first virtual space being a space allocated by a management node for the target file in a global virtual address space, the destination address of the access request containing information of a first storage node and the address of the target file in a local virtual address space in the first storage node, and the first storage node representing the storage node for storing the target file; the network device parses the destination address of the access request to acquire device information of the first storage node; and the network device transmits the access request to the first storage node according to the information of the first storage node to access the target file according to the address in the local virtual address space in the destination address. The file access method increases a file access efficiency.
