Abstract

A data distribution device and a data distribution method for use in a storage system including a plurality of storage servers are provided. The data distribution device includes a location recorder and a processor electrically connected with the location recorder. The location recorder is configured to record locations of a plurality of hypervisors and the storage servers. The processor is configured to capture information of at least one virtual machine related to the hypervisors; create a data distribution policy for the virtual machine according to the information and the locations of the hypervisors and the storage servers; and notify the storage system of the data distribution policy. The data distribution method is applied to the data distribution device to implement the aforesaid operations.

Claims

1. A data distribution device for use in a storage system, the storage system comprising a plurality of storage servers, the data distribution device comprising:

a location recorder, configured to record locations of a plurality of hypervisors and the storage servers; and

a processor, electrically connected with the location recorder and configured to;

capture information of at least one virtual machine related to the hypervisors;

create a data distribution policy for the at least one virtual machine according to the information and the locations of the hypervisors and the storage servers; and

notify the storage system of the data distribution policy.

2. The data distribution device as claimed in claim 1, wherein the processor notifies the storage servers of the data distribution policy so that the storage servers stores data of the at least one virtual machine according to the data distribution policy.

3. The data distribution device as claimed in claim 2, wherein the storage system further comprises at least one gateway server, and the processor further notifies the at least one gateway server of the data distribution policy so that the at least one gateway server controls access of the data between the at least one virtual machine and the storage servers according to the data distribution policy.

4. The data distribution device as claimed in claim 1, wherein the processor captures the information from a virtualization infrastructure system via a management application programming interface (API).

5. The data distribution device as claimed in claim 1, wherein the locations of the hypervisors and the storage servers are recorded in internet protocol form.

6. The data distribution device as claimed in claim 1, wherein the information of the at least one virtual machine comprises creation information, deletion information, startup information, poweroff information and migration information.

7. The data distribution device as claimed in claim 1, wherein the storage system is a scale-out network attached storage system.

8. A data distribution method of a data distribution device for use in a storage system, the storage system comprising a plurality of storage servers, the data distribution device comprising a location recorder and a processor electrically connected with the location recorder, the data distribution method comprising the following steps:

(a1) recording locations of a plurality of hypervisors and the storage servers by the location recorder;

(b1) capturing information of at least one virtual machine related to the hypervisors by the processor;

(c1) creating a data distribution policy for the at least one virtual machine according to the information and the locations of the hypervisors and the storage servers by the processor; and

(d1) notifying the storage system of the data distribution policy by the processor.

9. The data distribution method as claimed in claim 8, wherein the step (d1) further comprises the following step:

(d11) notifying the storage servers of the data distribution policy by the processor so that the storage servers stores data of the at least one virtual machine according to the data distribution policy.

10. The data distribution method as claimed in claim 9, wherein the storage system further comprises at least one gateway server, and the step (d1) further comprises the following step:

(d12) notifying the at least one gateway server of the data distribution policy by the processor so that the at least one gateway server controls access of the data between the at least one virtual machine and the storage servers according to the data distribution policy.

11. The data distribution method as claimed in claim 8, wherein the processor captures the information from a virtualization infrastructure system via a management application programming interface.

12. The data distribution method as claimed in claim 8, wherein the locations of the hypervisors and the storage servers are recorded in internet protocol form.

13. The data distribution method as claimed in claim 8, wherein the information of the at least one virtual machine comprises creation information, deletion information, startup information, poweroff information and migration information.

14. The data distribution method as claimed in claim 8, wherein the storage system is a scale-out network attached storage system.
