Abstract

A system and method for managing tables in a storage system is described.

Claims (44)

1. A storage system comprising:

a storage device;

a plurality of fingerprint tables comprising one or more entries corresponding to data stored in the storage device, the one or more entries having a corresponding probability of the data being deduplicated and wherein the one or more entries are added to a particular fingerprint table of the plurality of fingerprint tables that stores entries having a range of probabilities that the corresponding probability falls within; and

a storage controller communicatively coupled to the storage device, the storage controller configured to:

determine that an event has occurred; and

modify one of the plurality of fingerprint tables.

2. The storage system of claim 1 , wherein the plurality of fingerprint

tables comprises:

a first table comprising a first set of entries corresponding to data stored in the storage device which have likelihoods of deduplication that is greater than or equal to a threshold probability; and

a second table comprising a second set of entries corresponding to data stored in the storage device which have likelihoods of deduplication that is less than the threshold probability.

3. The storage system of claim 1 , wherein the storage controller is further

configured to:

maintain attributes corresponding to usage of data objects storage in the storage device; and

read the attributes corresponding to the objects, responsive to detecting the event.

4. The storage system as recited in claim 3 , wherein the attributes comprise one or more of: access, data age, device performance, device heath, error correction use data, deduplication rate, read shift voltage, frequency of update, and an error rate.

5. The storage system of claim 1 , wherein the event comprises one of: a garbage collection operation, a health binning operation, a block calibration operation, a device access operation and a wear levelling operation.

6. The storage system of claim 1 , wherein the storage controller is further configured to:

perform a data access to a fingerprint data of one of the plurality of fingerprint tables as part of a deduplication operation.

7. The storage system of claim 1 , wherein the data includes patterns.

8. The storage system of claim 1 , wherein the storage system is a flash system.

9. The storage system of claim 1 , wherein the one or more entries comprise hashes.

10. A method comprising:

determining that an event has occurred; and

modifying one of a plurality of fingerprint tables comprising one or more entries corresponding to data stored in a storage device, the one or more entries having a corresponding probability of the data being deduplicated and wherein the one or more entries are added to a particular fingerprint table of the plurality of fingerprint tables that stories entries having a range of probabilities that the corresponding probability falls within.

11. The method of claim 10 , wherein the plurality of fingerprint tables

comprises:

a first table comprising a first set of entries corresponding to data stored in the storage device which have likelihoods of deduplication that is greater than or equal to a threshold probability; and

a second table comprising a second set of entries corresponding to data stored in the storage device which have likelihoods of deduplication that is less than the threshold probability.

12. The method of claim 10 , further comprising:

maintaining attributes corresponding to usage of data objects storage in the storage device; and

reading the attributes corresponding to the objects, responsive to detecting the event.

13. The method as recited in claim 12 , wherein the attributes comprise one or more of: access, data age, device performance, device heath, error correction use data, deduplication rate, read shift voltage, frequency of update, and an error rate.

14. The method of claim 10 , wherein the event comprises one of: a garbage collection operation, a health binning operation, a block calibration operation, a device access operation and a wear levelling operation.

15. The method of claim 10 , further comprising:

performing a data access to a fingerprint data of one of the plurality of fingerprint tables as part of a deduplication operation.

16. The method of claim 10 , wherein the data includes patterns.

17. The method of claim 10 , wherein the storage device is a flash storage device.

18. The method of claim 10 , wherein the one or more entries comprise hashes.

19. A non-transitory, computer-readable medium comprising instructions which, when executed by a processing device of a storage system, cause the processing device to:

determine that an event has occurred; and

modify one of a plurality of fingerprint tables comprising one or more entries corresponding to data stored in a storage device, the one or more entries having a corresponding probability of the data being deduplicated and wherein the one or more entries are added to a particular fingerprint table of the plurality of fingerprint tables that stories entries having a range of probabilities that the corresponding probability falls within.

20. The non-transitory, computer readable storage medium of claim 19 , wherein the plurality of fingerprint tables comprises:

a first table comprising a first set of entries corresponding to data stored in the storage device which have likelihoods of deduplication that is greater than or equal to a threshold probability; and

a second table comprising a second set of entries corresponding to data stored in the storage device which have likelihoods of deduplication that is less than the threshold probability.
