ANSI 537:2016 pdf download.Information Technology一Zoned Device ATA Command Set(ZAC).
The set of AT Attachment standards consists of this standard and the ATA implementation standards described in AT Attachment – 8 ATAJATAPI Architecture Model (ATA8-AAM). This standard specifies the command set that host systems use to access storage devices that implement the Host Aware Zones feature set (see 4.3) or the Host Managed Zones feature set (see 4.4). This standard provides a common command set for systems manufacturers, system integrators, software suppliers, and suppliers of storage devices that provide one of the zones feature sets. Figure 1 shows the relationship of this standard to other ATA standards as well as related device and host standards and specifications (e.g., SCSI standards and SATA-lO specifications).
