Abstract
A pattern based space management apparatus and method for a computer system having at least two levels of hierarchical storage is comprised of computer code for creating and maintaining a data base containing size information and historical information about the use of data sets residing on the computer system. Code is provided for calculating a next reference date for certain of the data sets and a confidence level for each of the next reference dates from information in the data base. An input device may be used to define an amount of the highest level storage space which is to remain available. Code is provided for identifying which data sets should be migrated between the storage levels of the computer system based on the next reference dates, the confidence levels, the sizes of the data sets, and the amount of highest level storage space which is to remain available. Code is also provided to effect the migration of the data sets identified for migration.
