Abstract

The present disclosure relates to a data storage device having a hypervolume accessible by a plurality of servers operating on two or more data storage systems, a first physical volume, associated with the hypervolume, located at a first data storage system, and a second physical volume, associated with the hypervolume, located at a second storage system. The hypervolume directs input/output (I/O) from the servers to a primary physical volume comprising either the first or second physical volume, and the primary physical volume may be changed, transparently to the servers, to the other of the first or second physical volume. The present disclosure, in another embodiment, relates to a method for moving operation of a storage device from one data storage location to a second data storage location. A hypervolume is used to redirect input/output (I/O) from the a plurality of servers from the one physical volume to another.

Claims (39)

1. A data storage system comprising:

a first data storage center comprising two or more physical data storage devices and having a first volume defined from the two or more physical data storage devices of the first data storage center;

a first server communicatively coupled with the first data storage center, the first data storage center receiving input/output (I/O) requests from the first server;

a second data storage center comprising two or more physical data storage devices and having a second volume defined from the two or more physical data storage devices of the second data storage center;

a second server communicatively coupled with the second data storage center, the second data storage center receiving I/O requests from the second server; and

a hypervolume to which the first and second volumes are associated, and which directs I/O requests from the first and second servers, received via the first and second data storage centers, respectively, to a first one of the first and second volumes, designated as a primary volume;

wherein data stored to the primary volume as a result of the I/O requests is replicated to the other of the first and second volumes, designated as the secondary volume; and

wherein the designations of primary volume and secondary volume are automatically switched, by the data storage system via the hypervolume, between the first and second volumes, based on amounts of server I/O received via each of the data storage centers, so as to determine to which volume I/O requests are directed and to which volume replicated data is directed at any given time.

2. The data storage system of claim 1 , wherein the first and second data storage centers are located in different physical locations.

3. The data storage system of claim 1 , wherein data stored to the primary volume as a result of the I/O requests is replicated to the secondary volume using asynchronous replication.

4. The data storage system of claim 1 , wherein data stored to the primary volume as a result of the I/O requests is replicated to the secondary volume using synchronous replication.

5. The data storage system of claim 1 , wherein the designations of primary volume and secondary volume are additionally switched by the data storage system via the hypervolume when the primary volume is taken out of service.

6. A method for operation of a data storage system, wherein the data storage system comprises:

a first data storage center comprising two or more physical data storage devices and communicatively coupled with a first server, the first data storage center receiving input/output (I/O) requests from the first server; and

a second data storage center comprising two or more physical data storage devices and communicatively coupled with a second server, the second data storage center receiving I/O requests from the second server;

the method of operation comprising:

providing a first volume at the first data storage center and defined from the two or more physical data storage devices of the first data storage center;

providing a second volume at the second data storage center and defined from the two or more physical data storage devices of the second data storage center;

associating a hypervolume with the first and second volumes;

via the hypervolume, directing I/O requests from the first and second servers, received via the first and second data storage centers, respectively, to a first one of the first and second volumes, designated as a primary volume;

replicating data stored to the primary volume as a result of the I/O requests to the other of the first and second volumes, designated as the secondary volume; and

automatically switching, via the hypervolume, the designations of primary volume and secondary volume between the first and second volumes, based on amounts of server I/O received via each of the data storage centers, so as to determine to which volume I/O requests are directed and to which volume replicated data is directed at any given time.

7. The method for operation of a data storage system of claim 6 , wherein the first and second data storage centers are located in different physical locations.

8. The method for operation of a data storage system of claim 6 , wherein data stored to the primary volume as a result of the I/O requests is replicated to the secondary volume using asynchronous replication.

9. The method for operation of a data storage system of claim 6 , wherein data stored to the primary volume as a result of the I/O requests is replicated to the secondary volume using synchronous replication.

10. The method for operation of a data storage system of claim 6 , wherein the designations of primary volume and secondary volume are additionally switched via the hypervolume when the primary volume is taken out of service.

11. A hypervolume class of data volume storage presented by a data storage system comprising:

a first data storage center comprising two or more physical data storage devices and communicatively coupled with a first server, the first data storage center receiving input/output (I/O) requests from the first server; and

a second data storage center comprising two or more physical data storage devices and communicatively coupled with a second server, the second data storage center receiving I/O requests from the second server;

the hypervolume comprising:

a first volume at the first data storage center and defined from the two or more physical data storage devices of the first data storage center; and

a second volume at the second data storage center and defined from the two or more physical data storage devices of the second data storage center;

wherein the hypervolume directs I/O requests from the first and second servers, received via the first and second data storage centers, respectively, to a first one of the first and second volumes, designated as a primary volume;

wherein data stored to the primary volume as a result of the I/O requests is replicated to the other of the first and second volumes, designated as the secondary volume; and

wherein the designations of primary volume and secondary volume are automatically switched, via the hypervolume, between the first and second volumes, based on amounts of server I/O received via each of the data storage centers, so as to determine to which volume I/O requests are directed and to which volume replicated data is directed at any given time.

12. The hypervolume of claim 11 , wherein the first and second data storage centers are located in different physical locations.

13. The hypervolume of claim 11 , wherein data stored to the primary volume as a result of the I/O requests is replicated to the secondary volume using asynchronous replication.

14. The hypervolume of claim 11 , wherein data stored to the primary volume as a result of the I/O requests is replicated to the secondary volume using synchronous replication.

15. The hypervolume of claim 11 , wherein the designations of primary volume and secondary volume are additionally switched by the hypervolume when the primary volume is taken out of service.
