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.

A redundant cooling system with abatement of noise from cooling fans being used primarily in computer equipment and other boxes housing electronic equipment. Typically either the computer system or box housing electronic components has two parallel side panels, a front panel, and a back panel upon which cooling fans are mounted to draw air across various electronic components and through the box for heat dissipation. The cooling system includes an airflow grille attached to one end of a laminar flow duct and two adjacent cooling fans mounted to the other end of a laminar flow it duct which includes a Venturi opening on the top panel of the laminar flow duct to facilitate laminar flow through the laminar flow duct at a distance before the cooling fans and at a distance after the cooling fans.
