Abstract

A media management system including an application layer, a system layer, and a solid state drive (SSD) storage layer. The application layer includes a media data analytics application configured to assign a classification code to a data file. The system layer is in communication with the application layer. The system layer includes a file system configured to issue a write command to a SSD controller. The write command includes the classification code of the data file. The SSD storage layer includes the SSD controller and erasable blocks. The SSD controller is configured to write the data file to one of the erasable blocks based on the classification code of the data file in the write command. In an embodiment, the SSD controller is configured to write the data file to one of the erasable blocks storing other data files also having the classification code.

Claims

1. A media management system, comprising:

an application layer including a media data analytics application configured to assign a classification code to a data file having an expected life span, the classification code being indicative of the expected life span based on a content hotness level of the data file and a content type of the data file, the content hotness level and the content type being independent from each other;

a system layer in communication with the application layer, the system layer including a file system configured to issue a write command to a solid state drive (SSD) controller, the write command incorporating the classification code of the data file in an extension field of a header of the data file; and

an SSD storage layer in communication with the system layer, the SSD storage layer including the SSD controller and erasable blocks, the SSD controller configured to write the data file to one of the erasable blocks according to the classification code of the data file in the write command, there being multiple classification codes, one of the classification codes being system data, and the SSD storage layer being configured to store all media data assigned any of the multiple classification codes by the media data analytics application.

2. The media management system of claim 1, wherein the media data analytics application is configured to assign the classification code according to a predicted life span of the data file.

3. The media management system of claim 1, wherein the media data analytics application is configured to assign the classification code according to an actual life span of the data file.

4. The media management system of claim 1, wherein the media data analytics application is configured to assign the classification code according to at least one of historical information and metadata corresponding to the data file.

5. The media management system of claim 1, wherein the media data analytics application is configured to assign the classification code according to heuristic information corresponding to the data file.

6. The media management system of claim 1, wherein the media data analytics application is configured to assign the classification code according to contiguous portions of the data file.

7. The media management system of claim 1, wherein the media data analytics application is configured to receive the classification code from a content provider.

8. The media management system of claim 1, wherein the media data analytics application is configured to determine the classification code according to a likelihood that the data file remains in a cache associated with the file system.

9. The media management system of claim 1, wherein the classification code is multi-dimensional.

10. The media management system of claim 1, wherein the SSD controller is configured to write the data file to one of the erasable blocks storing other data files also having the classification code.

11. A computer system, comprising:

a processor configured to determine a classification code for a data file having an expected life span, the classification code in an extension field of a header of the data file, the classification code being indicative of the expected life span based on a content hotness level of the data file and a content type of the data file, and the content hotness level and the content type being independent from each other; and

a solid state drive (SSD) storage device in communication with the processor, the SSD storage device including an SSD controller and erasable blocks, the SSD controller configured to, based on the classification code contained in a write command, write the data file to one of the erasable blocks storing other data files also having the classification code, there being multiple classification codes, one of the classification codes being system data, and the SSD storage device configured to store all media data having any of the multiple classification codes determined by the processor.

12. The computer system of claim 11, further comprising a memory, the memory storing an application layer with a media data analytics application, the media data analytics application engaged by the processor to assign the classification code to the data file.

13. The computer system of claim 11, further comprising a memory, the memory storing a system layer with a file system configured to issue the write command to the SSD controller.

14. The computer system of claim 11, further comprising an input/output port configured to transport the data file to a network associated with the computer system.

15. The computer system of claim 11, further comprising at least one of a hard disk drive and an optical drive.

16. A method of media storage in a solid state drive (SSD), comprising:

receiving a classification code for a data file from a media data analytics application in an application layer, the classification code being indicative of an expected life span for the data file based on a content hotness level of the data file and a content type of the data file, the content hotness level and the content type being independent from each other; and

issuing a write command to a SSD controller, the write command instructing the SSD controller to store the data file in one of a plurality of erasable blocks according to the classification code of the data file in the write command, the classification code contained in an extension field of a header of the data file, there being multiple classification codes, one of the classification codes being system data, and the SSD controller storing all media data having any of the multiple classification codes received from the media data analytics application.

17. The method of claim 16, wherein the write command instructs the SSD controller to store the data file in the one of the plurality of erasable blocks where other data files also having the classification code are stored.

18. The method of claim 16, wherein the classification code is in accordance with at least one of a predicted life span and an actual life span of the data file.

19. The method of claim 16, wherein the classification code is in accordance with at least one of historical information and metadata corresponding to the data file.
