ANSI/INCITS 431-2007
This standard specifies a translation layer between SCSI and ATA protocols. This translation layer isused by storage controllers to emulate objects in a SCSI logical unit using an ATA device, providingcapabilities defined by SCSI standards (e.g., the SCSI Block Commands (SBC-2) and SCSI PrimaryCommands (SPC-3) standards). For the purposes of this standard, ATA device capabilities are definedby ATA8-AAM, ATA8-ACS, ATA8-APT, and SATA 2.5.
