| Zusammenfassung: | According to the present invention, methods and apparatus are provided improving reading of a remote tape device by a host through multiple fibre channel switches. A fibre channel switch preemptively sends read requests to a tape device before read requests are received from a host. Flow control, buffer management, and error handling mechanisms are implemented to allow accelerated tape back up restoration while working to prevent buffer overflow and underflow. |
