Described are techniques used in connection with management and processing of configuration data and performance data about a data storage system. The data is collected by one or more agents and forwarded to store components. The store components are responsible for maintaining persistent data objects in a repository. A server may process user requests issued from one or more consoles by retrieving data from the repository and displaying information based thereon on the consoles. The data collected by the agents may be in accordance with a first object model or data representation different from another object model or data representation of the repository. The store components update the repository using data collected by the agents.

Population of discovery data

In a managed information environment, such as a storage area network, a management application typically monitors and controls a plurality of manageable entities such as storage array devices. The manageable entities may emanate from multiple providers, or vendors, each having dissimilar interfaces and parameters. A common object model operable to normalize and represent device specific parameters that define a plurality of dissimilar manageable entities such as storage array devices enables interrogation and manipulation of the dissimilar storage devices for performing management and control via the management application. The management application selects, based on the device type, a representation in the common object model enumerating the device specific parameters of the storage device. Enumeration may involve identifying corresponding attributes between the device specific parameters and the attributes of the common object model, and copying, translating, or converting the corresponding fields. In this manner, the management application normalizes and performs manipulations of the dissimilar storage devices using the common object model.

System and methods for implementing an adaptive object model

Mechanisms and techniques for processing information in a network management application, such as a storage area network management application, include an agent and store process. The agent collects a current management data set from managed entity(s) in a network and compares the current management data set to a former management data set previously collected from the managed entity to identify differences in the current management data set as compared to the former management data set. The agent transmits the current management data set to a store process. The store process receives the current management data set and uses verification values and change indicators contained therein to identifying current portions of management data in the current management data that reflect a change. For any changed data portions, the store process modifies or updates managed object data in the management database.
