Abstract: A method and apparatus for enabling communication between iSCSI/SAS host devices and iSCSI/SAS target devices via an iSCSI/SAS router is disclosed. In one embodiment, an iSCSI/SAS router includes iSCSI interfaces, SAS interfaces, and a mapping and routing logic. The mapping and routing logic is coupled to the iSCSI interfaces and the SAS interfaces. The mapping and routing logic virtualizes one or more SAS host and target devices to communicate with discovered one or more iSCSI host and target devices. Further, the mapping and routing logic virtualizes the one or more iSCSI host and target devices to communicate with discovered one or more SAS host and target devices.

Abstract: The present invention is directed to a system and method for a quality assurance tool generating test plans and identifying new test requirements for a new version of a product. Old versions of the product may be previously tested and test plan documents associated with previously tested versions of the product may be stored in a database. The database may store test plans, test configurations, test scopes, and the like for previously tested versions of the product. Product design requirements may be determined based on received customer desired features for the new version. The database may be updated by adding new tests for new features of the new version. A test plan document for the product may be generated based on the updated database. The generated test document may be verified through automatically generating a general test plan for the new version of the product by querying updated database with the product design requirements.
