Abstract

A computing system for automatic discovery of a storage cluster. A computing system includes a discovery server, which receives a user-input including authentication credentials associated with a storage cluster. The discovery server executes a discovery pattern comprising a sequence of operations for a discovery of a set of resources associated with the storage cluster, based on the received user-input. One of the sequence of operations may correspond to transmission of a plurality of Application Programming Interface (API) calls to an Internet Protocol (IP) address of the storage cluster. The discovery server further receives a plurality of responses from the storage cluster. The plurality of responses includes information associated with the set of resources. The discovery server further generates a dependency map between the set of resources associated with the storage cluster based on the received information and outputs the generated dependency map.

First claim

at least one of the sequence of operations corresponds to transmission of a plurality of application programming interface (API) calls to an Internet Protocol (IP) address of the storage cluster;

receive a plurality of responses from the storage cluster based on the transmitted plurality of API calls, the received plurality of responses comprises information associated with the set of resources;
generate a dependency map between the set of resources associated with the storage cluster based on the received information; and
output the generated dependency map.

2. The computing system according to claim 1 , wherein the set of resources associated with the storage cluster comprises at least of: a set of nodes that comprise a set of drives.

3. The computing system according to claim 1 , wherein the discovery server is further configured to parse the received plurality of responses to determine the information associated with the set of resources.

4. The computing system according to claim 1 , wherein the authentication credentials are associated with a set of permissions, and wherein the set of permissions are required for authentication of each of the transmitted plurality of API calls to the IP address of the storage cluster.

5. The computing system according to claim 1 , wherein the discovery server is further configured to:
generate one or more configuration items (CIs) associated with the storage cluster, to be further stored in a configuration management database (CMDB) stored on the discovery server; and
generate the dependency map between the set of resources associated with the storage cluster further based on the generated one or more CIs.

6. The computing system according to claim 1 , wherein the discovery server is further configured to:
determine a relationship between one or more CI's associated with the storage cluster; and
generate a class model between the one or more CI's based on the determined relationship.

7. The computing system according to claim 6 , wherein the class model comprises at least one of:
