Systems and methods for object migration in storage devices

1. A method for storing data in a system comprising a plurality of storage devices, the method comprising:

obtaining object usage data from the plurality of storage devices, wherein the object usage data comprises:

a plurality of object identifiers;

a plurality of time periods;

a plurality of usage indicators each uniquely associated with an object identifier of the plurality of object identifiers and a time period of the plurality of time periods;

determining, using the object usage data, object clusters, wherein at least one object cluster of the object clusters comprises at least two objects that are associated based on access patterns; and

migrate a first object, of the at least two objects, from a first storage device of the plurality of storage devices to a second storage device of the plurality of storage devices; and

wherein the object usage data further comprises:

a first usage indicator identifies access to the first object at a first time period of the plurality of time periods; and

a second usage indicator identifies access to a second object, of the at least two objects, at the first time period,

wherein the second object is stored on the first storage device, and

wherein migrating the first object is based on the first usage indicator and the second usage indicator.

2. The method of claim 1 , wherein after migrating the first object, the method further comprises:

migrating a second object, of the at least two objects, to the second storage device, wherein the second storage device belongs to a different tier than the first storage device.

3. The method of claim 1 , wherein at least one of the plurality of storage devices is a magnetic storage device.

4. The method of claim 1 , wherein the first storage device of the plurality of storage devices is located on a first node in the system and the second storage device of the plurality of storage devices is located on a second node in the system.

5. A non-transitory computer readable medium comprising instructions which, when executed by a computer processor, enables the computer processor to perform a method for storing data in a system comprising a plurality of storage devices, the method comprising:

obtaining object usage data from the plurality of storage devices, wherein the object usage data comprises:

a plurality of object identifiers;

a plurality of time periods; and

a plurality of usage indicators each uniquely associated with an object identifier of the plurality of object identifiers and a time period of the plurality of time periods;

determining, using the object usage data, object clusters, wherein at least one object cluster of the object clusters comprises at least two objects that are associated based on access patterns; and

migrate a first object, of the at least two objects, from a first storage device of the plurality of storage devices to a second storage device of the plurality of storage devices,

wherein the object usage data further comprises:

a first usage indicator identifies access to the first object at a first time period of the plurality of time periods, and

a second usage indicator identifies access to a second object, of the two objects, at the first time period,

wherein the second object is stored on the first storage device, and

wherein migrating the first object is based on the first usage indicator and the second usage indicator.

6. The non-transitory computer readable medium of claim 5 , wherein after migrating the first object, the method further comprises:

migrating a second object, of the two objects, to the second storage device, wherein the second storage device belongs to a different tier than the first storage device.

7. The non-transitory computer readable medium of claim 5 , wherein at least one of the plurality of storage devices is a magnetic storage device.

8. The non-transitory computer readable medium of claim 5 , wherein the first storage device of the plurality of storage devices is located on a first node in the system and the second storage device of the plurality of storage devices is located on a second node in the system.

9. A node, comprising:

a plurality of storage devices; memory; and

a processor, wherein the processor is configured to perform a method for storing data in the node, the method comprising:

obtaining object usage data from the plurality of storage devices, wherein the object usage data comprises:

a plurality of object identifiers;

a plurality of time periods; and

a plurality of usage indicators each uniquely associated with an object identifier of the plurality of object identifiers and a time period of the plurality of time periods;

determining, using the object usage data, object clusters, wherein at least one object cluster of the object clusters comprises at least two objects that are associated based on access patterns; and

migrate a first object, of the two objects, from a first storage device of the plurality of storage devices to a second storage device of the plurality of storage devices,

wherein the object usage data further comprises:

a first usage indicator identifies access to the first object at a first time period of the plurality of time periods; and

a second usage indicator identifies access to a second object, of the two objects, at the first time period,

wherein the second object is stored on the first storage device,

wherein migrating the first object is based on the first usage indicator and the second usage indicator.

10. The node of claim 9 , wherein after migrating the first object, the method further comprises:

migrating a second object, of the two objects, to the second storage device, wherein the second storage device belongs to a different tier than the first storage device.

11. The node of claim 9 , wherein at least one of the plurality of storage devices is a magnetic storage device.
