Abstract

A computer storage system having a processor that supports operation of at least one software application in order to store selected data in the computer storage system, at least one storage media for storing the selected data, a plurality of storage policies, each having particular storage guidelines, that are available to determine how data is to be stored in the computer storage system, and a storage control that interacts with the at least one software application of the processor to determine which of the plurality of storage policies to use for storage of the selected data and that stores the selected data according to the selected storage policy. In one embodiment, the storage control of the computer storage system migrates the selected data from one of the at least one storage media to another of the at least one storage media according to the selected storage policy.

Claims

1. A computer storage system comprising:

a processor that supports operation of at least one software application that can be utilized to generate data that is stored in the computer storage system;

at least one storage media for storing selected data from the data that is generated;

a plurality of storage policies, each one of the plurality of storage policies including directions that the processor must follow for storage of data on the at least one storage media; and

a storage control that interacts with the at least one software application of the processor to select one of the plurality of storage policies and to determine, according to the selected one of the plurality of storage policies, which of the at least one storage media to use for storage of the selected data.

2. The computer storage system of claim 1 wherein the at least one storage media comprises a plurality of storage media that are selected from the group consisting of magnetic tape media, magnetic disk media, and optical medial.

3. The computer storage system of claim 1 wherein the storage control comprises a manager module that interacts with a media module to compile an index to track the location of the selected data in the at least one storage media.

4. The computer storage system of claim 1 wherein the storage control is configured to migrate the selected data among the at least one storage media according to the selected one of the plurality of storage policies.

5. The computer storage system of claim 1 wherein the plurality of storage policies are selected from the group consisting of storage sequences, storage logic, initial storage sequence selection criteria, storage sequence reselection criteria, and storage sequence adaptation criteria.

6. The computer storage system of claim 5 wherein the initial storage sequence selection criteria are selected from the group consisting of user directed override, user profile, application, file type, user network location, and available storage space.

7. The computer storage system of claim 5 wherein the storage sequence reselection criteria are selected from the group consisting of specific file usage history, file type usage history, user profile, user network relocation, available storage space, and added storage media.

8. The computer storage system of claim 5 wherein the storage sequence adaptation criteria are selected from the group consisting of specific file usage history, user profile, user network relocation, available storage space, and added storage media.

9. A computer storage system comprising:

a processor that supports operation of at least one software application in order to store selected data in the computer storage system;

at least one storage media for storing the selected data;

a plurality of storage policies, each having particular storage guidelines, that are available to determine how data is to be stored in the computer storage system; and

a storage control that interacts with the at least one software application of the processor to determine which of the plurality of storage policies to use for storage of the selected data and that stores the selected data according to the selected storage policy.

10. The computer storage system of claim 9 wherein the storage control migrates the selected data from one of the at least one storage media to another of the at least one storage media according to the selected storage policy.

11. A method for storing data on one of a plurality of storage media of a computer storage system according to one of a plurality of storage policies that are defined by a user, the method comprising:

directing a software application to store selected data;

examining the selected data for particular characteristics;

selecting a particular storage policy that matches the particular characteristics of the selected data; and

storing the selected data on a storage media of the computer storage system according to the particular storage policy.

12. The method of claim 11 further comprising migrating the selected data among the plurality storage media according to the particular storage policy.
