A controller, system, method and computer program for emulating one or more tape-based storage devices using non-tape based physical data storage media. The controller is adapted to generate a data set for indicating an available capacity of the one or more emulated tape-based storage devices, the data set includes capacity data for indicating a respective available capacity of the one or more emulated tape-based storage devices based on an available capacity of the non-tape-based physical data storage media. The controller is also adapted to provide access to data stored on the non-tape based physical data storage medium using tape-based media command and the data set, and to dynamically update the capacity data of the data set in response to a change in the available capacity of the non-tape-based physical data storage media.
