CLI Guide

NOTE: ODX provides a way to transfer data without using buffered read and buffered write
operations and does not require direct host involvement with the data transfer operation. When
ODX is not enabled, data is read from the source storage to the host, and then written to the target
storage from the host. With ODX enabled, the data transfer operations are directly managed by the
storage infrastructure. The data is moved directly from the source storage to the target storage
without going through the host.
