16. A storage aggregation apparatus for virtualizing data access commands, comprising:
an input and output interface linking the storage aggregation apparatus to a digital data communication fabric, wherein the interface receives a data access command from a host server over the fabric;
a command processor configured to parse a data movement portion from the data access command and to transmit the data movement portion to a storage controller; and
a mechanism for receiving a reply signal from the storage controller in response to acting on the received data movement portion directly with the host server and for transmitting a data access response to the host server via the interface and fabric based on the storage controller reply signal.
