System and method for providing a common data model for SAN discovery and/or SAN monitoring information collected from heterogeneous SAN components. In one embodiment, a SAN management server may execute on a host computer and may translate data in one or more vendor-specific languages obtained from a heterogeneous vendor population into canonical data in a uniform language. In one embodiment, the SAN management server may execute a set of rules to convert heterogeneous SAN data obtained from heterogeneous interfaces into canonical data conforming to the common data model. In one embodiment, the canonical data may be stored in a persistent store, which may be queried for information that may be provided to the requestor in the canonical form of the common data model.
