Methods and systems for automatically adding intelligent storage adapters to a cluster
View Patent ↗Methods and systems for automatically creating a cluster are provided. The method includes discovering at least a first and a second intelligent storage adapter, determining if the first or the second intelligent storage adapter is operating within a cluster, and when neither the first or the second intelligent storage adapter are a part of any cluster, then automatically generating a cluster with a unique identifier and assigning one of the first or the second intelligent storage adapters as a master of the cluster.
1. A machine-implemented method, comprising:
discovering at least a first and a second intelligent storage adapter;
determining if the first or the second intelligent storage adapter is operating within a cluster;
when neither the first nor the second intelligent storage adapter are a part of any cluster, then automatically generating a cluster with a unique identifier and assigning one of the first or the second intelligent storage adapters as a master of the cluster;
discovering a third intelligent storage adapter by the master intelligent storage adapter of the cluster; and
the master intelligent storage adapter automatically adding the third intelligent storage adapter to the cluster, when the third intelligent storage adapter is not a member of any cluster.
2. The method of claim 1 , wherein the master intelligent storage adapter notifies the third intelligent storage adapter that it has been added to the cluster.
3. The method of claim 1 , wherein the master intelligent storage adapter maintains a data structure for identifying the cluster and members of the cluster.
4. The method of claim 1 , wherein the master intelligent storage adapter operates as a host bus adapter to access a storage area network storage device and manages storage space at a local storage device.
5. The method of claim 1 , wherein the master intelligent storage adapter processes input/output requests for members of the cluster for any cached logical unit number (LUN).
6. A non-transitory, machine readable storage medium storing executable instructions, which when executed by a machine, causes the machine to perform a method, the method comprising:
discovering at least a first and a second intelligent storage adapter;
determining if the first or the second intelligent storage adapter is operating within a cluster;
when neither the first or the second intelligent storage adapter are a part of any cluster, then automatically generating a cluster with a unique identifier and assigning one of the first or the second intelligent storage adapters as a master of the cluster;
discovering a third intelligent storage adapter by the master intelligent storage adapter of the cluster; and
the master intelligent storage adapter automatically adding the third intelligent storage adapter to the cluster, when the third intelligent storage adapter is not a member of any cluster.
7. The storage medium of claim 6 , wherein the master intelligent storage adapter notifies the third intelligent storage adapter that it has been added to the cluster.
8. The storage medium of claim 6 , wherein the master intelligent storage adapter maintains a data structure for identifying the cluster and members of the cluster.
9. The storage medium of claim 6 , wherein the master intelligent storage adapter operates as a host bus adapter to access a storage area network storage device and manages storage space at a local storage device.
10. The storage medium of claim 6 , wherein the master intelligent storage adapter processes input/output requests for members of the cluster for any cached logical unit number (LUN).
11. A system comprising:
a processor executing instructions out of a memory for:
discovering at least a first and a second intelligent storage adapter;
determining if the first or the second intelligent storage adapter is operating within a cluster;
when neither the first or the second intelligent storage adapter are a part of any cluster, then automatically generating a cluster with a unique identifier and assigning one of the first or the second intelligent storage adapters as a master of the cluster;
discovering a third intelligent storage adapter by the master intelligent storage adapter of the cluster; and
the master intelligent storage adapter automatically adding the third intelligent storage adapter to the cluster, when the third intelligent storage adapter is not a member of any cluster.
12. The system of claim 11 , wherein the master intelligent storage adapter notifies the third intelligent storage adapter that it has been added to the cluster.
13. The system of claim 11 , wherein the master intelligent storage adapter maintains a data structure for identifying the cluster and members of the cluster.
14. The system of claim 11 , wherein the master intelligent storage adapter operates as a host bus adapter to access a storage area network storage device and manages storage space at a local storage device.
15. The system of claim 11 , wherein the master intelligent storage adapter processes input/output requests for members of the cluster for any cached logical unit number (LUN).
