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.
