    摘要： A storage virtualization system for accessing at least one storage device for a virtual logical unit (VLUN) from at least one host. The system includes at least one upstream processing element (UPE) which is adapted for coupling to a corresponding host server. The system is further adapted for coupling to at least one storage device. The controller also includes a primary central processing element (CPE) that can be configurably coupled to the UPEs. The primary CPE permits data transfer to occur between a host and a storage device via the corresponding UPE. The controller further includes a backup CPE that can be configurably coupled to the UPEs. The backup CPE is configurable to permit the data transfer when the primary CPE becomes unavailable.

    摘要： An apparatus and method for testing a network-based storage virtualization system. A tester is connected to a host side of a storage virtualization system. The tester provides test scripts to the storage virtualization system to test I/O and other operations. A separate link, independent of said storage virtualization system, is provided to a storage side of said storage virtualization system to allow verification of the correct translation from virtual to physical independent of the data path used by the virtualization system. Thus, the tester verifies, over the separate link, the physical configuration of VLUNs and data written to the VLUNs by the tester on storage devices.
