Abstract

A method, computer readable medium, and system that handles a multi-protocol name in a virtualization environment includes determining and predicting with a virtualization management computing device when a name collision occurs between content names of different content accessible by two or more protocols. The virtualization management computing device restricts access to the different content in one or more network attached storage devices when the name collision is determined to occur to one or more of the protocols which can distinguish the different content. It preserves access to the different content in certain cases where the collision can be predicted.

Claims

1. A method for handling a multi-protocol name in a virtualization environment, the method comprising:

determining with a virtualization management computing device when a name collision occurs between content names of different content accessible by two or more protocols, the determining further comprises determining when an original content name for incoming content matches a generated name pattern used by the virtualization management computing device and determining when a name collision occurs between the original content name and a stored content name for stored content in one or more network attached storage devices accessible via the two or more protocols when a match is determined between the original content name and the generated name pattern; and

restricting with the virtualization management computing device all access to the different content in the one or more network attached storage devices when the name collision is determined to occur to one or more of the protocols which can distinguish the different content, the restricting restricts access to the incoming content with the original content name and the stored content when the name collision is determined to occur to one or more of the protocols which can distinguish different files.

2. The method as set forth in claim 1 wherein the determining further comprises determining with the virtualization management computing device when the name collision occurs between a generated content name for incoming content and a stored content name for stored content in one or more of the network attached storage devices accessible to the two or more protocols;

wherein the restricting restricts access to the incoming content with the generated content name and the stored content when the name collision is determined to occur to one or more of the protocols which can distinguish the different files.

3. The method as set forth in claim 2 further comprising:

determining with the virtualization management computing device when one or more of the protocols is unable to represent an original content name for incoming content; and

generating with the virtualization management computing device the generated content name for the incoming content.

4. The method as set forth in claim 1 further comprising providing with the virtualization management computing device notification of the determined name collision.

5. The method as set forth in claim 1 wherein the two or more protocols comprise NFS and CIFS.

6. A non-transitory computer readable medium having stored thereon instructions for methods for handling a multi-protocol content name in a virtualization environment comprising machine executable code which when executed by at least one processor, causes the processor to perform steps comprising:

determining when a name collision occurs between content names of different content accessible by two or more protocols, the determining further comprises determining when an original content name for incoming content matches a generated name pattern used by the virtualization management computing device and determining when a name collision occurs between the original content name and a stored content name for stored content accessible via the two or more protocols when a match is determined between the original content name and the generated name pattern; and

restricting all access to the different content in one or more network attached storage devices when the name collision is determined to occur to one or more of the protocols which can distinguish the different content, the restricting restricts access to the incoming content with the original content name and the stored content when the name collision is determined to occur to one or more of the protocols which can distinguish different files.

7. The medium as set forth in claim 6 wherein the determining further comprises determining when the name collision occurs between a generated content name for incoming content and the stored content name for the stored content accessible to the two or more protocols;

wherein the restricting restricts access to the incoming content with the generated content name and the stored content when the name collision is determined to occur to one or more of the protocols which can distinguish the different files.

8. The medium as set forth in claim 7 further comprising:

determining when one or more of the protocols is unable to represent an original content name for the incoming content; and

generating the generated content name for the incoming content.

9. The medium as set forth in claim 6 further comprising providing notification of the determined name collision.

10. The medium as set forth in claim 6 wherein the two or more protocols comprise NFS and CIFS.

11. A virtualization management computing device comprising:

at least one of a configurable logic device configured to implement or one or more processors configured to execute programmed instructions stored in a memory device comprising;

determining when a name collision occurs between content names of different content accessible by two or more protocols, the determining further comprising determining when an original content name for incoming content matches a generated name pattern used by the virtualization management computing device and determining when a name collision occurs between the original content name and a stored content name for stored content in one or more of the network attached storage devices accessible via the two or more protocols when a match is determined between the original content name and the generated name pattern; and

restricting all access to the different content in one or more network attached storage devices when the name collision is determined to occur to one or more of the protocols which can distinguish the different content, the restricting restricts access to the incoming content with the original content name and the stored content when the name collision is determined to occur to one or more of the protocols which can distinguish different files.

12. The device as set forth in claim 11 wherein, the at least one of the configurable logic device is further configured to implement or the one or more processors are further configured to execute programmed instructions stored in the memory wherein the determining further comprises:

determining when the name collision occurs between a generated content name for incoming content and a stored content name for stored content in one or more of the network attached storage devices accessible to the two or more protocols;

wherein the restricting restricts access to the incoming content with the generated content name and the stored content when the name collision is determined to occur to one or more of the protocols which can distinguish the different files.

13. The device as set forth in claim 12 wherein, the at least one of the configurable logic device is further configured to implement or the one or more processors are further configured to execute programmed instructions stored in the memory further comprising:

determining with the virtualization management computing device when one or more of the protocols is unable to represent an original content name for the incoming content;

and

generating with the virtualization management computing device a generated content name for the incoming content.

14. The device as set forth in claim 11 wherein the at least one of the configurable logic device is further configured to implement or the one or more processors are further configured to execute programmed instructions stored in the memory further comprising providing notification of the determined name collision.

15. The device as set forth in claim 11 wherein the two or more protocols comprise NFS and CIFS.
