Abstract

Provided are data structures for use in storing data. A plurality of data structures are defined in a computer readable medium, wherein each data structure indicates a plurality of attributes and at least one function of a storage resource to store data. Policies are defined in the computer readable medium that associate data characteristics to data structures based on a correspondence of data characteristics and the attributes defined in the data structures, wherein each defined data structure is adapted to provide requirements to determine a storage resource to store associated data, and wherein the defined data structure is adapted to provide the storage resource with requirements for storing the data.

6. The method of claim 1, wherein the policies comprise storage policies concerning management and configuration of a storage space for data, and further comprising:

generating a storage policy manager that processes the data structures to determine the data structure having attributes corresponding to determined characteristics of the associated data.

7. The method of claim 6, wherein storage vendors provide storage policies, storage policy managers, and the data structure to associate storage policies with their storage resources.

8. The method of claim 6, wherein the storage policy manager determines the storage resource associated with the determined data structure and transmits the data to the determined storage resource.

9. A computer implemented method for storing data in a computer readable medium, comprising:

determining attributes corresponding to data characteristics of the data;

processing a plurality of data structures in a computer readable medium, wherein each data structure indicates a plurality of attributes and at least one function, to determine one data structure having attributes corresponding to the determined characteristics of the data, wherein a storage resource is associated with the determined data structure, and wherein the storage resource associated with the determined data structure implements the attributes and functions indicated in the data structure, wherein each defined data structure is configured to provide requirements to determine a storage resource to store the data, and wherein each defined data structure is configured to provide the storage resource with functions that invoke at least one of hardware and software to perform storing the data in a manner that satisfies the attributes and requirements defined by the data structure; and

using the at least one function indicated by the determined data structure to store the data in a manner that satisfies the attributes and requirements defined by the determined data structure.

10. The method of claim 9, wherein an application policy maps the attributes and at least one function data to the data structures, wherein the application policy concerns an application requirements with respect to data, and wherein an application policy manager processes the data structures to determine the data structure having attributes corresponding to the determined characteristics of the data.

11. The method of claim 10, wherein different application vendors provide application policies and application policy managers to associate storage policies with data generated by their applications.

12. The method of claim 9, wherein a data policy maps the attributes and at least one function to the data structures, wherein the data policy concerns criteria for management of the data life cycle, recoverability, and security, and wherein a data policy manager processes the data structures to determine the data structure having attributes corresponding to the determined characteristics of the data.

13. The method of claim 12, wherein middleware vendors provide data policies and data policy managers to associate storage policies with data generated by their middleware.

14. The method of claim 9, wherein a storage policy maps the attributes and at least one function to the data structures, wherein the storage policy concerns management and configuration of a storage space for data, and wherein a storage policy manager processes the data structures to determine the data structure having attributes corresponding to the determined characteristics of the data.

15. The method of claim 14, wherein storage vendors provide storage policies and storage policy managers to associate storage policies with their storage resources.

16. The method of claim 14, wherein the storage policy manager determines the storage resource associated with the determined data structure and transmits the data to the determined storage resource.
