A report generator of a storage area network management application includes a data validation mechanism that validates data related to managed resources operating in a storage area network. The data validation mechanism obtains first and second data sets concerning first and second characteristics of a resource operating in the storage area network and applies at least one data validation test using data sets to detect inconsistencies in data in the first and second data sets associated with the resource operating in the storage area network. Values can be compared in different columns of the same or different reports to detect report integrity errors or data mining errors. The report generator provides a storage area network management report based on data of the first data set and the second data set that accounts for inconsistencies in data associated with the resource as detected by the at least one data validation test.

Methods and apparatus for performing data validation in a network management application

Historical access information identifies which resources in a storage area network access portions of shared storage in the storage area network. Based on an analysis of the historical access information, a management report generator application analyzing such information can infer the existence of a cluster of resources that access a common portion of shared storage. When the management report generator identifies that two or more resources access the same storage resources during approximately the same timeframe, the management report generator knows that there is a high likelihood that the two or more resources are part of a cluster sharing access to common storage resources. Thus, when reporting a tally of storage resources used in the storage area network, it is possible for the management report generator to take into account the cluster and indicate that two resources share access to a common portion of storage.
