Abstract

According to one embodiment, a system includes a data storage device having data stored therein and a native computer system having resident thereon a controlling operating system in communication with the data storage device. The system also includes a primary computer system having resident thereon a primary operating system in communication with the native computer system via a first connection, the primary computer system being in communication with the data storage device via a second connection that is not in communication with the native computer system, the primary computer system having a processor executing a primary application. A volume on the data storage device is under logical control of the controlling operating system of the native computer system, and the primary computer system reads or writes data to the volume directly via the second connection. Other systems, methods and computer program products are also described relating to accessing data.

Claims

1. A system, comprising:

at least one data storage device having data stored therein;

at least one native computer system in communication with the at least one data storage device, the at least one native computer system having resident thereon a controlling operating system; and

at least one primary computer system in communication with the at least one native computer system via at least one first connection, the at least one primary computer system being in communication with the at least one data storage device via at least one second connection that is not in communication with the at least one native computer system, the at least one primary computer system having resident thereon a primary operating system, the at least one primary computer system having a processor executing a primary application,

wherein a volume on the at least one data storage device is under logical control of the controlling operating system of the at least one native computer system,

wherein the at least one primary computer system reads or writes data to the volume directly via the at least one second connection.

2. The system of claim 1, wherein the at least one second connection has a higher data throughput rate than the at least one first connection.

3. The system of claim 1, wherein the at least one first connection includes a network protocol connection, wherein the at least one second connection includes a fiber optic cable.

4. The system of claim 1, wherein the at least one native computer system runs an agent for assisting in coordinating accesses to the at least one data storage device by the at least one native and primary computer system.

5. The system of claim 1, wherein the at least one primary computer system sends a request to the at least one native computer system via the at least one first connection, the request requesting access to a dataset in the volume by the primary application, wherein the at least one native computer system verifies that the primary application has permission to access the dataset and sends permission information to the at least one primary computer system if the primary application has permission to access the dataset, wherein the at least one primary computer system uses the permission information to access the dataset on the at least one data storage device directly using the at least one second connection.

6. The system of claim 5, wherein the at least one native computer system prevents access to the dataset by applications other than the primary application during a time period when the at least one primary computer system is accessing the dataset for the primary application.

7. The system of claim 6, wherein the at least one primary computer system sends a message to the at least one native computer system via the at least one first connection that the access to the dataset is finished, wherein the at least one native computer system stops preventing access to the dataset by applications other than the primary application.

8. A method, comprising:

sending a request from a primary computer system to a native computer system via a first connection, the request requesting access to a dataset in a volume stored on a data storage device by a primary application running on the primary computer system, wherein the volume is under logical control of the native computer system;

receiving permission information from the native computer system if the primary application has permission to access the dataset; and

using the permission information to access the dataset on the data storage device directly via a second connection that is not in communication with the native computer system.

9. The method of claim 8, wherein the second connection has a higher data throughput rate than the first connection.

10. The method of claim 8, wherein the first connection includes a network protocol connection, wherein the second connection includes a fiber optic cable.

11. The method of claim 8, wherein the native computer system prevents access to the dataset by applications other than the primary application during a time period when the primary computer system is accessing the dataset for the primary application.

12. The method of claim 11, wherein the primary computer system sends a message to the native computer system via the first connection that the access to the dataset is finished, wherein the native computer system stops preventing access to the dataset by applications other than the primary application.

13. A method, comprising:

receiving at a native computer system a request from a primary computer system via a first connection, the request requesting access to a dataset in a volume stored on a data storage device by a primary application running on the primary computer system, wherein the volume is under logical control of the native computer system;

determining whether the primary application has permission to access the dataset;

sending permission information to the primary computer system if the primary application has permission to access the dataset; and

preventing access to the dataset by applications other than the primary application during a time period when the primary computer system is accessing the dataset for the primary application.

14. The method of claim 13, wherein the primary computer system accesses the dataset via a second connection that is not in communication with the native computer system.

15. The method of claim 14, wherein the second connection has a higher data throughput rate than the first connection.

16. The method of claim 13, further comprising running an agent for assisting in coordinating accesses to the data storage device by the native and primary computer systems.

17. The method of claim 13, further comprising receiving a message from the primary computer system via the first connection that the access to the dataset is finished, and further comprising stopping the preventing access to the dataset by applications other than the primary application upon receiving the message.

18. A computer program product, the computer program product comprising:

a computer readable medium having computer readable program code embodied therewith, the computer readable program code comprising;

computer readable program code configured to receive at a native computer system a request from a primary computer system via a first connection, the request requesting access to a dataset in a volume stored on a data storage device by a primary application running on the primary computer system, wherein the volume is under logical control of the native computer system;

computer readable program code configured to determine whether the primary application has permission to access the dataset;

computer readable program code configured to send permission information to the primary computer system if the primary application has permission to access the dataset; and

computer readable program code configured to prevent access to the dataset by applications other than the primary application during a time period when the primary computer system is accessing the dataset for the primary application.

19. The computer program product of claim 18, further comprising computer readable program code configured to run an agent for assisting in coordinating accesses to the data storage device by the native and primary computer systems.

20. The computer program product of claim 18, further comprising:

computer readable program code configured to receive a message that the access to the dataset is finished from the primary computer system via the first connection; and

computer readable program code configured to stop preventing access to the dataset by applications other than the primary application upon receiving the message.
