Abstract

A computing system includes: a name node block configured to: determine a data node including a high performance device, select a target device, wherein the data node, coupled to the name node block, is configured to: perform a first copy write command to the high performance device, provide a transaction status as completed for the first copy write command, and a replication tracker block, coupled to the data node, configured to perform a background replication to replicate a data content from the first copy write command to the target device after the transaction status is provided as completed.

Claims

1. A computing system comprising:

a name node block configured to;

determine a data node including a high performance device,

select a target device;

wherein the data node, coupled to the name node block, is configured to;

perform a first copy write command to the high performance device,

provide a transaction status as completed for the first copy write command; and

a replication tracker block, coupled to the data node, configured to perform a background replication to replicate a data content from the first copy write command to the target device after the transaction status is provided as completed.

2. The system as claimed in claim 1 wherein the replication tracker block is configured to perform the background replication to replicate the data content to the target device representing another instance of the data node.

3. The system as claimed in claim 1 wherein the replication tracker block is configured to perform the background replication to replicate the data content to the target device representing a low performance device.

4. The system as claimed in claim 1 wherein the replication tracker block is configured to execute a write command for the background replication for writing the data content to the storage unit different from the storage unit where the first copy write command is completed.

5. The system as claimed in claim 1 wherein the replication tracker block is configured to communicate a restart request based on a transaction status for failing to complete the first copy write command, the background replication, or a combination thereof.

6. The system as claimed in claim 1 further comprising the data node configured to receive the data content from an intermediate storage for performing the first copy write command to the data node.

8. The system as claimed in claim 1 further comprising the data node configured to receive a write command for performing the first copy write command to a solid state drive over a hard disk drive.

9. The system as claimed in claim 1 wherein the replication tracker block is configured to perform the background replication to a hard disk drive after the first copy write command is performed on a solid state drive.

10. The system as claimed in claim 1 wherein the replication tracker block is configured to communicate a restart request for reissuing a write command to replicate the data content.

7. The system as claimed in claim further comprising an intermediate storage configure to delete the data content based on a transaction status for completing the first copy write command, the background replication, or a combination thereof.

11. A method of operation of a computing system comprising:

performing a first copy write command for writing to a high performance device;

providing a transaction status as completed for the first copy write command; and

performing a background replication with a replication tracker block for replicating a data content from the first copy write command to a target device after the transaction status is provided as completed.

12. The method as claimed in claim 11 wherein performing the background replication includes performing the background replication for replicating the data content to the target device representing a data node different from the data node where the first copy write command is completed.

13. The method as claimed in claim 11 wherein performing the background replication includes performing the background replication for replicating the data content to the target device representing a low performance device.

14. The method as claimed in claim 11 further comprising executing a write command for the background replication for writing the data content to a storage unit different from the storage unit where the first copy write command is completed.

15. The method as claimed in claim 11 further comprising communicating a restart request based on a transaction status for failing to complete the first copy write command, the background replication, or a combination thereof.

16. A non-transitory computer readable medium including instructions for execution by a computer block comprising:

performing a first copy write command for writing to a high performance device;

providing a transaction status as completed for the first copy write command; and

performing a background replication for replicating a data content from the first copy write command to a target device after the transaction status is provided as completed.

17. The non-transitory computer readable medium as claimed in claim 16 wherein performing the background replication includes performing the background replication for replicating the data content to the target device representing a data node different from the data node where the first copy write command is completed.

18. The non-transitory computer readable medium as claimed in claim 16 wherein performing the background replication includes performing the background replication for replicating the data content to the target device representing a low performance device.

19. The non-transitory computer readable medium as claimed in claim 16 further comprising executing a write command for the background replication for writing the data content to a storage unit different from the storage unit where the first copy write command is completed.

20. The non-transitory computer readable medium as claimed in claim 16 further comprising communicating a restart request based on a transaction status for failing to complete the first copy write command, the background replication, or a combination thereof.
