Abstract

A system, method, and computer program product are provided for sending failure information from a solid state drive (SSD) to a host device. In operation, an error is detected during an operation associated with a Serial ATA (SATA) solid state drive. Additionally, a command is received for failure information from a host device. Further, the failure information is sent from the solid state drive to the host device, the failure information including failure information associated with the solid state drive.

Claims

1. A method, comprising:

detecting an error during an operation associated with a Serial ATA (SATA) solid state drive (SSD);

receiving a command for failure information from a host device; and

sending the failure information from the SSD to the host device, the failure information including failure information associated with the SSD.

2. The method of claim 1, wherein the failure information includes information indicating whether data stored in at least a portion of the SSD is corrupt.

3. The method of claim 1, wherein the failure information includes information indicating a location of the SSD associated with the error.

4. The method of claim 1, wherein the failure information includes information indicating whether the SSD was able to free up space for a command associated with the operation.

5. The method of claim 1, wherein the failure information includes information indicating whether the error is associated with one of a persistent failure or a transient failure.

6. The method of claim 1, wherein the failure information is included in a log page.

7. The method of claim 6, wherein the log page further includes information indicating where the SSD is on a life expectancy curve.

8. The method of claim 6, wherein the log page further includes vendor specific information.

9. The method of claim 6, wherein the log page further includes one or more fields associated with a read log 10 page.

10. The method of claim 6, wherein the log page is capable of being utilized to recover failure information associated with an NCQ command issued to the SSD.

11. The method of claim 6, wherein the log page is capable of being utilized to recover failure information associated with a non-queued command issued to the SSD.

12. The method of claim 1, wherein the command includes a command that is capable of being used to fetch SSD information to recover from an NCQ command and failure information associated with the NCQ command.

13. The method of claim 1, wherein the failure information is accessible utilizing a command to fetch SSD failure information.

14. The method of claim 1, wherein the failure information is accessible utilizing a Read Log EXT command.

15. The method of claim 1, wherein the failure information is accessible utilizing a Read Log DMA command.

16. The method of claim 1, wherein the failure information is included in a log page 10.

17. The method of claim 1, wherein the operation includes sending an NCQ command.

18. The method of claim 1, wherein the operation includes sending a SATA command.

19. A computer program product embodied on a computer readable medium, comprising:

computer code for detecting an error during an operation associated with a Serial ATA (SATA) solid state drive (SSD);

computer code for receiving a command for failure information from a host device; and

computer code for sending the failure information from the SSD to the host device, the failure information including failure information associated with the SSD.

20. An apparatus, comprising:

a Serial ATA (SATA) solid state drive (SSD) configured to;

detect an error during an operation associated with the SSD;

receive a command for failure information from a host device; and

send the failure information from the SSD to the host device, the failure information including failure information associated with the SSD.
