A solution for managing data in which historical execution information for a process is used to determine a set of data requirements for the process. The set of data requirements is then used to move data for the process from a slower storage device (e.g., a magnetic tape) to a faster storage device (e.g., a hard drive) before the process requests the data object (e.g., prefetch). In this manner, the prefetched data can be provided when requested by the process without delaying its execution while the data is moved from the slower storage device to the faster storage device.

Predictive data object retrieval

A system, method and program product for assigning management classes to data objects. The disclosed system includes a class assignment system for assigning a management class to an inputted data object, wherein the class assignment system analyzes historical usage characteristics of existing data objects that have attributes similar to the inputted data object; and a data analysis system that analyzes existing data objects to generate a knowledge base of historical usage characteristics. The historical usage characteristics are updated as existing objects make their way through the storage lifecycle.

Method for automated data storage management

The present invention is directed to the automated storage and retrieval of data. A method in accordance with an embodiment of the present invention includes: requesting a data record; broadcasting a query for the requested data record to a plurality of data records in a data center, the query comprising a unique listener key identifying the requested data record and information regarding a requesting program; providing each of the plurality of data records with a listener, wherein each listener actively monitors the broadcasted query to determine if the unique listener key in the broadcasted query matches a unique listener key of the data record associated with the listener; and in the case of a match, automatically transferring the data record with the matching unique listener key from the data center to the requesting program.
