A METHOD FOR DETERMINING ALLOCATABILITY OF TAPE DRIVES TO SERVE REQUESTS TO STORE INFORMATION

摘要

The present invention is a method for testing if modifications made to the lists of tape drives available to serve requests in a modified request queue allow n different tape drives to be assigned to n requests. The three embodiments of the present invention each test the modified lists in a manner that determines, not only if the number of tape drives assigned is sufficient to serve the number of requests, but whether the tape drives are assigned in a way that allows n different tape drives to serve n requests.
