A method of servicing a command sent from a host device file system (HDFS)
within a host device (HD) by a local storage device (LSD) in
communication with the HD is described. The method includes receiving a
first command at the LSD instructing the LSD to execute an operation on
associated logical addresses. If the first command is associated with at
least a first set of logical addresses, the method includes servicing the
first command by the LSD at least by way of sending a second command to a
device (RD) external to the LSD that instructs the RD to execute an
operation on memory locations within the RD. If the first command is not
associated with the first set of logical addresses, the method includes
servicing the first command by the LSD only by way of operations executed
by the LSD on memory locations within the LSD.
