Abstract: In a subrack with multiple boards, in order to enable a server board and at least one client board of the multiple boards to access a same storage device, an embodiment server board acquires, physical information of at least one physical storage device. Then the server board sends a client board the physical information to enable the client board to establish a virtue storage device and receives a first request for accessing the virtual storage device sent from the client board. The server board convertes the first request for accessing the virtual storage device into a second request for accessing the physical storage device, and sends the second request for accessing the physical storage device to a storage controller connected to the physical storage device in order to enable the storage controller to send relevant data to the client.
