Abstract

Systems and methods for reducing problems and disadvantages associated with protecting data during cold excursions are provided. A method for preventing unreliable data operations at cold temperatures may include determining whether a first temperature of a solid state drive (SSD) is below a threshold temperature. The method may also include initiating an artificial read/write operation if the first temperature is below the threshold temperature.

Claims

1. A method for preventing unreliable data operations at cold temperatures comprising:

determining whether a first temperature of a solid state drive (SSD) is below a threshold temperature;

initiating an artificial read/write operation on the SSD to increase the first temperature if the first temperature is below the threshold temperature; and

sampling a second temperature of the SSD.

2. The method of claim 1, wherein sampling a second temperature of the SSD is completed following a pre-defined time interval.

3. The method of claim 2, wherein the pre-defined time interval is based on an event.

4. The method of claim 2, wherein the pre-defined time interval is provided by a user.

5. The method of claim 1, further comprising proceeding with a read/write operation if the second temperature of the SSD is above the threshold temperature.

6. The method of claim 1, wherein the artificial read/write operation comprises a plurality of SSD controller transactions.

7. The method of claim 1, wherein the threshold temperature is provided by a user.

8. An information handling system comprising:

a solid state drive (SSD);

a processor communicatively coupled to the SSD and configured to;

determine whether a first temperature of the SSD is below a threshold temperature;

initiate an artificial read/write operation on the SSD to increase the first temperature if the first temperature is below the threshold temperature; and

sample a second temperature of the SSD.

9. The system of claim 8, wherein sampling a second temperature of the SSD is completed following a pre-defined time interval.

10. The system of claim 9, wherein the pre-defined time interval is based on an event.

11. The system of claim 9, wherein the pre-defined time interval is provided by a user.

12. The system of claim 8, wherein the processor is further configured to pause a read/write operation if the second temperature of the SSD is below the threshold temperature.

13. The system of claim 8, herein the processor is further configured to proceed with a read/write operation if the second temperature of the SSD is above the threshold temperature.

14. The system of claim 8, wherein the artificial read/write operation comprises a plurality of SSD controller transactions.

15. The system of claim 8, wherein the threshold temperature is provided by a user.

16. A non-transitory computer-readable medium comprising instructions stored therein, the instructions readable by a processor and, when read and executed, configured to cause the processor to:

determine whether a first temperature of a solid state drive (SSD) is below a threshold temperature;

initiate an artificial read/write operation on the SSD to increase the first temperature if the first temperature is below the threshold temperature; and

sample a second temperature of the SSD.

17. The medium of claim 16, wherein sampling a second temperature of the SSD is completed following a pre-defined time interval.

18. The medium of claim 16, wherein the instructions further cause the processor to pause a read/write operation if the second temperature of the SSD is below the threshold temperature.

19. The system of claim 16, herein the instructions further cause the processor to proceed with a read/write operation if the second temperature of the SSD is above the threshold temperature.
