Abstract:

The present invention is a system and method for reconciling results returned from a multi-protocol scan of a NAS system. Certain NAS systems use different protocols. Some may use the NFS protocol, whereas others may use the CIFS protocol. A scan of the NAS may therefore produce two data object names for a single data object. When a storage virtualization system is tasked with acting as an intermediary between the client and the NAS, these two data object names will cause errors during data migration, synchronization or redirection. The present invention is a method for using the results of a multi-protocol scan of the NAS in order to reconcile data object names that may present differently depending on the protocol applied.
