Abstract

Deployment of new elements in a computer network can result in development of patch kits adapters, and other software and trigger corresponding regressive test efforts. In a storage area network, a method is disclosed for defining a general, extensible model of a manageable entity for use in management of the entity. The method includes obtaining a set of attribute values related to the manageable entity in relation to the storage area network. A deployment engine identifies corresponding entity categories within a storage area network entity model that contains attribute definitions that correspond to respective attribute values in the set of attribute values obtained from the manageable entity. The deployment engine assigns the respective attribute values of the manageable entity to the corresponding respective attribute definitions identified in the model. The deployment engine then determines if all attribute values of the manageable entity have been assigned. If unassigned attribute values remain, a classification processor defines new entity categories to contain new attribute definitions, and assigns the unassigned attributes value to the new attribute definitions contained in the new entity category.

Claims

1. A computer program product, stored on a non-transitory computer readable storage medium, having a data structure stored thereon for adaptive storage element deployment in a storage area network, the data structure comprising:

attributes having associated attribute values of an object to be deployed in the network, the attribute values indicative of network characteristics of the object;

identified attribute definitions in a predetermined set of top level objects adapted to be compared to the attributes of the object to be deployed to determine a matching top level object, each of the top level objects in the set of top level objects having an entity category, matching top level objects being in the same entity category and sharing an attribute definition;

successive attributes corresponding to the matching top level object and indicative of matching object generic attributes corresponding to matching attributes of the object to be added, the successive attributes defining a plurality of levels, the data structure adapted to receive attribute values for entity categories at successive levels;

object specific attribute definitions corresponding to the unmatching attributes adapted to be defined and classified for creating attribute definitions in the data structure corresponding to the unmatching attributes; and

object generic attribute definitions adapted to receive the associated attribute values corresponding to the object to be deployed, the attribute definitions for receiving attribute value pairs indicative of the attribute definition and corresponding attribute value, and the successive ancillary attributes defining a plurality of level, the data structure adapted to receive attribute values for entity categories at successive levels of the plurality of levels.

2. The computer program product of claim 1 wherein the attribute definitions are for receiving attribute value pairs indicative of the attribute definition and corresponding attribute value.

3. The computer program product of claim 2 wherein the attribute value pairs are further indicative of the corresponding entity category for each of the particular attribute value defined in the attribute value pair.

4. The computer program product of claim 1 wherein the object to be deployed is a manageable entity in a storage area network, the manageable entity having an element specification file indicative of object specific attribute definitions.

5. The computer program product of claim 4 wherein the data structure is adapted to receive an element specification file corresponding to the manageable entity to be defined and operable to be parsed for defining the new entity category and corresponding attributes.

6. The computer program product of claim 1 wherein the data structure is responsive to an agent component corresponding to the defined new entity category, such that the agent components corresponding an existing entity category are predefined.

7. The computer program product of claim 6 wherein the object to be deployed is a connectivity device in a storage area network, the connectivity device operable to provide connectivity between a set of storage arrays and an infrastructure server for accessing data in the storage array.

8. The computer program product of claim 6 wherein the object to be deployed is a manageable entity in a storage area network, the manageable entity responsive to a corresponding agent for monitoring and controlling the manageable entity.

9. The computer program product of claim 8 wherein the manageable entity is a zone, the zone indicative of a subset of the manageable entities in the storage area network and adapted to provide selective access control to the manageable entities in the zone.

10. The computer program product of claim 8 wherein the manageable entity is a database and assigning the respective attribute values further comprises assigning attribute values including at least one of vendor, instance type of DB, owner, group, schema characteristics, and DB object characteristics.

11. The computer program product of claim 8 wherein the manageable entity is a host in communication with a set of other storage area network element and assigning the respective attribute values further comprises assigning attribute values including at least one of operating system, IP address, file server, host device characteristics, agent components, and storage arrays.

12. A method of component reuse in a storage area network defined by a model of entity category templates, each entity category corresponding to a component, comprising:

identifying a top-level entity category corresponding to a network element to be deployed, each entity category having an attribute definition including attributes common to components in that entity category;

identifying, for each of a set of successive levels in the model from the identified top-level category, ancillary categories corresponding to the attributes of the network element to be deployed;

defining, for each of the attributes corresponding to an identified category, attribute values derived from an instantiation of an existing component in the same entity category as the network element to be deployed; and

repeating the identifying and defining in an iterative manner for the ancillary categories at successive levels of the model of entity category templates.

13. The method of claim 12 further comprising:

determining if there is at least one unassigned attribute value in the attribute values of the network element to be deployed, and if so;

defining at least one new entity category containing at least one new attribute definition that corresponds to the at least one unassigned attribute value.

14. The method of claim 13 further comprising assigning the at least one unassigned attribute value to a corresponding one of the at least one new attribute definition contained in the at least one new entity category.

15. The method of claim 13 wherein the defining further comprises:

creating, for each of the unassigned attribute values, an attribute definition; and

storing, in the created attribute definition, the unassigned attribute value.

16. The method of claim 15 wherein the step of determining further comprises parsing an element specification file corresponding to the network element to be defined, the network element being a storage area network element further comprising at least one of a subtype, the subtypes including storage array, host, or connectivity device, and identifying the corresponding entity category includes determining the subtype of storage area network element.

17. The method of claim 12 wherein the step of identifying further comprises:

traversing a hierarchical structure having levels defined by the entity categories of the model of entity categories; and

iteratively comparing, at each successive level of the hierarchical structure, the unassigned attribute values to the attribute definitions in the entity categories at that level of the hierarchy.

18. A computer program product including computer program code embodied as a set of instructions on a computer readable storage medium that, when executed by a computer responsive to the instructions cases the computer to perform steps for invoking a data structure for adaptive storage element deployment in a storage area network comprising:
