A method for automatically (i.e., programmatically) determining a storage configuration for a storage system for a given application. The method may receive information on existing storage capabilities in the storage system and information regarding the software application that will use the storage system. The method may then automatically determine a storage configuration for the storage system based on the existing storage capabilities in the storage system, the information regarding the application, and application specific rules about storage configuration principles of the application. The rule may comprise priority information that specifies a priority in application of the rules, e.g., a structure or list of storage types in order of priority for different application data types.
