SCSI-3 Extended Copy

Server-Free data movement uses the SCSI-3 EXTENDED COPY command and are carried out by a data mover device that must exists on the SAN, and it is the data mover device that is responsible for copying the data, either from a SAN-attached (client-owned) disk to a SAN-attached tape drive (server-owned), or vice versa. From the T10 working group, "The EXTENDED COPY command provides a means to copy data from one set of logical units to another set of logical units or to the same set of logical units. The entity within a SCSI device that receives and performs the EXTENDED COPY command is called the copy manager. The copy manager is responsible for copying data from the source devices to the destination devices. The copy source and destination devices are logical units that may reside in different SCSI devices or the same SCSI device."
