System and method for a simulation of a block storage system on an object storage system

1. A computerized method of simulating a block storage system on an object storage system, the method comprising:

creating a simulated block storage system on the object storage system, by defining a plurality of logical parts of the simulated block storage system and storing data included in the logical parts in a respective plurality of objects in the object storage system, wherein data included in a logical part is stored in at least one respective object; and

when receiving a notification of a write operation in the simulated block storage system:

creating a new object in the object storage system and storing the data of the write operation in the new object, and

updating a range-map to include at least one of: a reference to the new object, a logical address of the data of the write operation, and a size of the data of the write operation, and a counter.

2. The method of claim 1 , comprising:

receiving a request to read data, the request including an address range;

examining the range-map to identify objects in the object storage that store data related to the address range; and

responding to the request based on data stored in at least one of: the plurality of objects and the new object.

3. The method of claim 1 , comprising:

including a value of a running counter in names of the objects;

sorting a plurality of objects based on the counter value; and

creating the range-map by recording a reference to an object, a logical address of the object, a size of the object and a counter value.

4. The method of claim 3 , comprising creating the range-map by recording at least one of: a time and date value, an identification of a user and an identification of an application.

5. The method of claim 1 , comprising:

determining the set of objects in the object storage system that include data included in a set of logical parts; and

if the number of objects in the set is greater than a threshold value then:

initializing a storage object having a size of the set of logical parts,

storing, in the storage object, data read from objects in the object storage system that include data included in the set of logical parts,

creating a new object in the object storage system and storing data read from the storage object in the new object, and

updating the range-map to include at least: a reference to the new object, a logical address of the modified data, a size of the modified data and a counter.

6. The method of claim 5 , comprising deleting at least some of the objects in the object storage system that include data included in the set of logical parts.

7. The method of claim 5 , wherein the set of logical parts includes one logical part.

8. The method of claim 1 , wherein the range-map is an in-memory object.

9. The method of claim 5 , comprising removing the set of objects from the object storage system.

10. A computerized method of simulating a block storage system on an object storage system, the method comprising:

logically dividing the simulated block storage system into a set of logical parts and storing data included in the logical parts in a respective set of objects in the object storage system, wherein data included in a logical part is stored in at least one respective object; and

when a write operation is performed in the simulated block storage system:

creating a new object in the object storage system and including the data of the write operation in the new object, and

modifying a map to include at least one of: a reference to the object, a logical address of the data of the write operation, a size of the data of the write operation, and a running counter.

11. A system comprising:

a memory; and

a controller configured to:

define a plurality of logical parts of a simulated block storage system and store data included in the logical parts in a respective plurality of objects in an object storage system, wherein data included in a logical part is stored in at least one respective object; and

when receiving a notification of a write operation in the simulated block storage system:

create a new object in the object storage system and store the data of the write operation in the new object, and

update a range-map to include at least one of: a reference to the new object, a logical address of the data of the write operation, a size of the data of the write operation and a counter.

12. The system of claim 11 , wherein the controller is configured to:

receive a request to read data, the request including an address range;

examine the range-map to identify objects in the object storage that store data related to the address range; and

respond to the request based on data stored in at least one of: the plurality of objects and the new object.

13. The system of claim 11 , wherein the controller is configured to:

include a value of a running counter in names of the objects;

sort a plurality of objects based on the counter value; and

create the range-map by recording a reference to an object, a logical address of the object, a size of the object and a counter value.

14. The system of claim 13 , wherein the controller is configured to create the range-map by recording at least one of: a time and date value, an identification of a user and an identification of an application.

15. The system of claim 11 , wherein the controller is configured to:

determine the set of objects in the object storage system that include data included in a set of logical parts; and

if the number of objects in the set is greater than a threshold value then:

initialize a storage object having a size of the set of logical parts,

store, in the storage object, data read from objects in the object storage system that include data included in the set of logical parts,

create a new object in the object storage system and storing data read from the storage object in the new object, and

update the range-map to include at least: a reference to the new object, a logical address of the modified data, a size of the modified data and a counter.

16. The system of claim 15 , wherein the controller is configured to delete at least some of the objects in the object storage system that include data included in the set of logical parts.

17. The system of claim 15 , wherein the set of logical parts includes one logical part.

18. The system of claim 11 , wherein the range-map is an in-memory object.

19. The system of claim 15 , wherein the controller is configured to remove the set of objects from the object storage system.

20. The system of claim 11 , wherein the controller is configured to create the range-map based on names of objects in object storage system.
