Abstract:
1. A controller for emulating one or more tape-based storage devices having a nominal data capacity using non-tape based physical data storage media, wherein 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 comprising 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, and the respective available capacity being different from the nominal data capacity, to provide access to data stored on the non-tape based physical data storage medium using tape-based media commands 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.
