A system provides a user map service that receives component data associated with a resource in a storage area network and matches the component data to entries in a user-created component matching database to determine a specific identity of the resource in the storage area network to which the component data is associated. The system provides the specific identity of the resource in the storage area network to which the component data is associated. The system maintains the user-created component matching database by allowing a user to create matches between individual resources for which component data is received to specific identities of those resources as determined by the user. The database can be queried and updated to make matching more efficient.
