In a computer system with a disk array that has physical storage devices arranged as logical storage units and is capable of carrying out hardware storage operations on a per logical storage unit basis, a switch is provided to offload storage operations from a file system to storage hardware. The switch translates primitives used for performing storage operations into commands executable by the physical storage devices so that the data moving portion of the storage operations can be offloaded from the file system to the storage devices.
