A StorageVolume is an Extent that is presented to the Operating System (for example, by a hardware RAID cabinet), to a File System (for example, by a software volume manager) or to another entity. StorageVolumes do NOT participate in StorageRedundancy Groups. They are directly Realized in hardware or are the end result of assembling lower level Extents.
