Abstract

A system receives managed resource data collected by an agent from a managed resource in a storage area network. The system evaluates conditions associated with the managed resource data to select a read mechanism based on the conditions, and applies the read mechanism to read managed object data from the managed object database. The managed object data corresponds to the managed resource data. After application of the read mechanism, the system synchronizes the managed object data from the managed object database with the managed resource data collected from the managed resource.
