Abstract

Improved access management techniques for storage networks are described. In one embodiment, for example, an apparatus may comprise a processor circuit and an access control component for execution by the processor circuit to select a set of hosts for which to enable access to a logical storage volume of a network storage cluster, select, from among a plurality of nodes of the network storage cluster, a set of nodes via which to enable access to the logical storage volume by the set of hosts, and generate a storage configuration object comprising a parameter identifying the set of nodes. Other embodiments are described and claimed.

Claims

1. A non-transitory machine-readable medium having stored thereon instructions for performing a method comprising executable code that, when executed by at least one machine, causes the machine to:

select one or more clients for which to enable access to a logical storage volume of a network storage cluster and a first set of a plurality of nodes of the network storage cluster via which to enable access to the logical storage volume by the one or more clients;

generate a storage configuration object comprising a parameter identifying the first set of nodes as associated with the logical storage volume, wherein the first set of nodes comprises an owner node of the logical storage volume and a partner node of the owner node, the owner node and the partner node comprising a high-availability pair; and

report a first set of logical interfaces (LIFs) to the one or more clients, the first set of LIFs determined based on the association of the first set of nodes and the logical volume in the storage configuration object and corresponding to one or more ports of the first set of nodes via which the one or more clients can access the logical storage volume.

2. The non-transitory machine-readable medium of claim 1, wherein the logical storage volume is coupled to at least one node of the first set of nodes via a cluster interconnect.

3. The non-transitory machine-readable medium of claim 2, the first set of nodes exclusively comprising the owner node and the partner node.

4. The non-transitory machine-readable medium of claim 1, the storage configuration object identifying a logical unit number (LUN) of the logical storage volume as associated with the first set of nodes.

5. The non-transitory machine-readable medium of claim 1, wherein the machine executable code when executed by the machine, further causes the machine to:

migrate the logical storage volume from a first node in the first set of nodes to a second node in a second set of the plurality of nodes of the network storage cluster, the second set of nodes different from the first set of nodes;

update the storage configuration object to associate the second set of nodes with the logical storage volume instead of the first set of nodes; and

report a second set of LIFs determined based on the updated storage configuration object to the one or more clients.

6. The non-transitory machine-readable medium of claim 1, wherein the machine executable code when executed by the machine, further causes the machine to generate a group configuration object identifying the one or more clients, the storage configuration object comprising information associating the group configuration object with the logical storage volume.

7. A computing device, comprising:

a memory containing a machine readable medium comprising machine executable code having stored thereon instructions for performing a method of providing data sessions with clients that access data containers of a shared storage; and

a processor coupled to the memory, the processor configured to execute the machine executable code to cause the processor to;

select one or more clients for which to enable access to a logical storage volume of a network storage cluster and a first set of a plurality of nodes of the network storage cluster via which to enable access to the logical storage volume by the one or more clients;

generate a storage configuration object comprising a parameter identifying the first set of nodes as associated with the logical storage volume, wherein the first set of nodes comprises an owner node of the logical storage volume and a partner node of the owner node, the owner node and the partner node comprising a high-availability pair; and

report a first set of logical interfaces (LIFs) to the one or more clients, the first set of LIFs determined based on the association of the first set of nodes and the logical volume in the storage configuration object and corresponding to one or more ports of the first set of nodes via which the one or more clients can access the logical storage volume.

8. The computing device of claim 7, wherein the logical storage volume is coupled to at least one node of the first set of nodes via a cluster interconnect.

9. The computing device of claim 8, the first set of nodes exclusively comprising the owner node and the partner node.

10. The computing device of claim 7, the storage configuration object identifying a logical unit number (LUN) of the logical storage volume as associated with the first set of nodes.

11. The computing device of claim 7, the processor further configured to execute the machine executable code to cause the processor to:

migrate the logical storage volume from a first node in the first set of nodes to a second node in a second set of the plurality of nodes of the network storage cluster, the second set of nodes different from the first set of nodes;

update the storage configuration object to associate the second set of nodes with the logical storage volume instead of the first set of nodes; and

report a second set of LIFs determined based on the updated storage configuration object to the one or more clients.

12. The computing device of claim 7, processor further configured to execute the machine executable code to cause the processor to generate a group configuration object identifying the one or more clients, the storage configuration object comprising information associating the group configuration object with the logical storage volume.

13. A method, comprising:

selecting, by the computing device, one or more clients for which to enable access to a logical storage volume of a network storage cluster and a first set of a plurality of nodes of the network storage cluster via which to enable access to the logical storage volume by the one or more clients;

generating, by the computing device, a storage configuration object comprising a parameter identifying the first set of nodes as associated with the logical storage volume, wherein the first set of nodes comprises an owner node of the logical storage volume and a partner node of the owner node, the owner node and the partner node comprising a high-availability pair; and

reporting, by the computing device, a first set of logical interfaces (LIFs) to the one or more clients, the first set of LIFs determined based on the association of the first set of nodes and the logical volume in the storage configuration object and corresponding to one or more ports of the first set of nodes via which the one or more clients can access the logical storage volume.

14. The method of claim 13, wherein the logical storage volume is coupled to at least one node of the first set of nodes via a cluster interconnect.

15. The method of claim 14, the first set of nodes exclusively comprising the owner node and the partner node.

16. The method of claim 13, the storage configuration object identifying a logical unit number (LUN) of the logical storage volume as associated with the first set of nodes.

17. The method of claim 13, further comprising:

migrating, by the computing device, the logical storage volume from a first node in the first set of nodes to a second node in a second set of the plurality of nodes of the network storage cluster, the second set of nodes different from the first set of nodes;

updating, by the computing device, the storage configuration object to associate the second set of nodes with the logical storage volume instead of the first set of nodes; and

reporting, by the computing device, a second set of LIFs determined based on the updated storage configuration object to the one or more clients.

18. The method of claim 13, further comprising generating, by the computing device, a group configuration object identifying the one or more clients, the storage configuration object comprising information associating the group configuration object with the logical storage volume.
