Abstract:
In one embodiment, a method is provided for adapting a host transfer rate between a host and a tape drive to a medium transfer rate between the tape drive and a tape. A data compression rate of untransferred data in a buffer of a tape drive is measured. A change in a future host transfer rate is predicated based on the measured compression rate. A host transfer rate between a host and the tape drive is adapted to a medium transfer rate between the tape drive and a tape, based on the predicted change.
