Abstract: An agent collecting management data from the resource operating in the managed network to form a management data set and identifies segregated regions of management data within the management data set. Each segregated region is a respective partial transitive closure of the collected management data taken over a graph representing the entire management data set. For each segregated region of management data, the agent partitions that segregated region of management data into a set of logical partitions and transfers each logical partition of the segregated region of management data to a network management application in the managed network for access by the network management application. A network management application receives the partitions and only needs to keep objects in memory related to partitions that are currently received and being processed thus saving memory and processing resources.

Abstract: A custom host naming mechanism that allows a user to define a custom host name as a virtual name for the hosts in the managed information environment, such as the storage area network, overcomes the shortcomings of the use of a network assigned machine name during a failover operation. The custom host naming mechanism allows the operator to define a mnemonic virtual name for each host in the managed information environment, thereby facilitating failover switching. Further, such secondary hosts may undertake offline, lower priority executing tasks while not in failover mode, and rapidly reconfigure as the failover secondary host should the need arise. Therefore, secondary hosts at a hot site deploy with a mnemonically descriptive name indicative of their status as a secondary host for a corresponding primary host, and further, need not remain idle pending a disaster recovery scenario, but rather are employable for offloading of other, lower priority tasks pending failover response.

Abstract: 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.
