ABSTRACT:
The present invention provides for a data storage system having a number of virtual storage devices. Each of the virtual storage devices may include a number of physical storage devices. The physical storage devices need not be separately addressable by a host system. Each virtual storage device unit may comprise a field replaceable unit encompassing no more than a single virtual storage device. Physical storage devices included in a virtual storage device that are not in active use may be powered down, even while one or more other physical devices included in that virtual storage device are powered up.
