A disk drive storage enclosure includes one cooling path for storage media and a separate cooling path for non-drive storage support equipment such as controller hardware, power supplies, circuit memory, processors, etc. Within the enclosure, storage media are stored up front, with non-drive storage support equipment stored at rear. The storage media and non-drive equipment are separated by a central ventilating chamber. In one cooling path, intake air enters the storage media from the enclosure's front face, then passes into the central ventilating chamber before exhausting through the chamber's side wall. A separate cooling path serves the non-drive storage support equipment. In this path, intake air passes laterally through the non-drive storage support equipment. The cooling paths are driven by fan assemblies, which may include redundant fan units with shutoff gates that are automatically activated if a fan unit fails to prevent back flow.
