Abstract: Disclosed is a method for creating a large-scale storage array by combining multiple mid-range storage arrays via a host based aggregation engine software application. Each mid-range storage array, also call a storage building block, consists of one or more RAID volumes. Each mid-range storage array has equivalent configuration and property settings including number of drives, RAID level, volume segment sizes, and volume cache settings, but not including the volume label. The complex combination of mid-range storage arrays appears as a single storage system to a data management application of a host computer system. Once the mid-range storage arrays are aggregated into a large-scale storage array, or storage complex array, common features may be modified as a collection of items so that a common modification need only be entered one time for all items in the collection.

Abstract: A method for testing a provider in a common information model. The method generally includes the steps of (A) generating a test case class of the common information model, the test case class residing in a class hierarchy of an object-oriented model, (B) generating a client test case class of the common information model below the test case class in the class hierarchy, the client test case class defining control of at least one logical configuration for the provider and (C) generating an instance tester class of the common information model below the client test case class in the class hierarchy, the instance tester class defining at least one verification module for testing the provider.

Abstract: The present invention is a method and system for translating method calls to version-specified method calls. An interface to an underlying object is provided. Applications communicating with the underlying object use the interface. The interface is separate from the underlying object. Version-specific underlying objects are generated. Each one of the version-specific underlying objects is a different version of the underlying object. A plurality of translation objects, one for each version-specific underlying object, are generated for communicating between the interface and each one of the version-specific underlying objects. A translation object is used for translating an interface method call invoked on the interface to a version-specific method call for the underlying object for each version of the underlying object. All translation objects are generated from a single proxy class and a single invocation handler class.
