摘要
A virtual sequential data storage (VSDS) system includes a VSDS controller coupled to physical data storage and a host machine with at least one host application. The controller is configured to carry out commands from the host application referencing VSDS. A router installed at the host intercepts prescribed types of host application commands directed to the controller. For each intercepted read/write command, the router determines a target physical location in physical data storage to carry out the intercepted host read/write command. Also, if the host application command is a read command, the router transfers data requested by the read command from the target physical location to the host application bypassing the controller. If the host application command is a write command, the router transfers write data associated with the write command from the host application to the target physical location bypassing the controller.
