Abstract: A data access method, a routing apparatus, and a storage system are provided. The method is applied to a storage system including a first storage device, a second storage device, and a routing apparatus. A logical unit in each storage device includes at least one first-type logical block and at least one second-type logical block. According to the method, when sending access requests to the storage devices in the storage system according to a preset rule, the routing apparatus sends access requests corresponding to same target logical blocks to one of the storage devices according to a preset rule. This reduces network overheads between the storage system and the application server, and improves efficiency of processing the access requests by the storage system.

Abstract: A file management method, a distributed storage system, and a management node are disclosed. In the distributed storage system, after receiving a file creation request sent by a host for requesting to create a file in a distributed storage system, a management node allocates, to the file, first virtual space from global virtual address space of the distributed storage system, where local virtual address space of each storage node in the distributed storage system is corresponding to a part of the global virtual address space. Then, the management node records metadata of the file, where the metadata of the file includes information about the first virtual space, and the information about the first virtual space is used to point to local virtual address space of a storage node that is used to store the file. Further, the management node sends, the information about the first virtual space to the host.
