Abstract

An embodiment of the invention provides a method comprising: permitting an application to be aware to be aware of a distribution of a data of the application across a cache and a permanent storage device. The cache comprises a solid state device and the permanent storage device comprises a disk or a memory. In yet another embodiment of the invention, an apparatus comprises: a caching application program interface configured to permit an application to be aware to be aware of a distribution of a data of the application across a cache and a permanent storage device. A caching application program interface is configured to determine an input/output strategy to consume the data based on the distribution of the data.

Claims

1. A method, comprising:

permitting an application to be aware to be aware of a distribution of a data of the application across a cache and a permanent storage device.

2. The method of claim 1, wherein the cache comprises a solid state device and the permanent storage device comprises a disk.

3. The method of claim 1, wherein the cache comprises a solid state device and the permanent storage device comprises a memory.

4. The method of claim 1, wherein the cache comprises a solid state device and the permanent storage device comprises a disk and a memory.

5. The method of claim 1, wherein based on the distribution of the data, determining an input/output strategy to consume the data.

6. The method of claim 1,

wherein blocks residing in the cache are available for the application to process.

7. The method of claim 6,

wherein the blocks residing in the permanent storage device are available for the application to subsequently process.

8. An apparatus, comprising:

a caching application program interface configured to permit an application to be aware to be aware of a distribution of a data of the application across a cache and a permanent storage device.

9. The apparatus of claim 8, wherein the cache comprises a solid state device and the permanent storage device comprises a disk.

10. The apparatus of claim 8, wherein the cache comprises a solid state device and the permanent storage device comprises a memory.

11. The apparatus of claim 8, wherein the cache comprises a solid state device and the permanent storage device comprises a disk and a memory.

12. The apparatus of claim 8, wherein based on the distribution of the data, the caching application program interface is configured to determine an input/output strategy to consume the data.

13. The apparatus of claim 8,

wherein blocks residing in the cache are available for the application to process.

14. The apparatus of claim 13,

wherein the blocks residing in the permanent storage device are available for the application to subsequently process.

15. An article of manufacture, comprising:

a non-transient computer-readable medium having stored thereon instructions that permit a method comprising;

permitting an application to be aware to be aware of a distribution of a data of the application across a cache and a permanent storage device.

16. The article of manufacture of claim 15, wherein the cache comprises a solid state device and the permanent storage device comprises a disk.

17. The article of manufacture of claim 15, wherein the cache comprises a solid state device and the permanent storage device comprises a memory.

18. The article of manufacture of claim 15, wherein the cache comprises a solid state device and the permanent storage device comprises a disk and a memory.

19. The article of manufacture of claim 15, wherein the method further comprises:

based on the distribution of the data, determining an input/output strategy to consume the data.

20. The article of manufacture of claim 15,

wherein blocks residing in the cache are available for the application to process.
