The purpose of the architecture model is to provide a common basis for the coordination of ATA standards and to define those aspects of ATA

3、 system behavior that are independent of a particular technology and common to all implementations.Approval of an American National Standard requires review by ANSI that therequirements for due process, consensus, and other criteria for approval havebeen met by the standards developer.Consensus is e

4、stablished when, in the judgement of the ANSI Board ofStandards Review, substantial agreement has been reached by directly andmaterially affected interests. Substantial agreement means much more thana simple majority, but not necessarily unanimity. Consensus requires that allviews and objections be

5、considered, and that a concerted effort be madetowards their resolution.The use of American National Standards is completely voluntary; theirexistence does not in any respect preclude anyone, whether he has approvedthe standards or not, from manufacturing, marketing, purchasing, or usingproducts, pr

6、ocesses, or procedures not conforming to the standards.The American National Standards Institute does not develop standards andwill in no circumstances give an interpretation of any American NationalStandard. Moreover, no person shall have the right or authority to issue aninterpretation of an Ameri

7、can National Standard in the name of the AmericanNational Standards Institute. Requests for interpretations should beaddressed to the secretariat or sponsor whose name appears on the titlepage of this standard.CAUTION NOTICE: This American National Standard may be revised orwithdrawn at any time.

27、word (This foreword is not part of American National Standard INCITS 451-2008.)The purpose of this standard is to provide a basis for the coordination of ATA stan-dards development and to define requirements common to all ATA technologies andimplementations that are essential for compatibility with

28、host ATA application soft-ware and device-resident firmware across all ATA transport protocols. These require-ments are defined through a reference model that specifies the behavior and abstractstructure that is generic to all ATA I/O system implementations.Requests for interpretation, suggestions f

29、or improvement and addenda, or defect re-ports are welcome. They should be sent to the INCITS Secretariat, National Commit-tee for Information Technology Standards, Information Technology Institute, 1250Eye Street, NW, Suite 200, Washington, DC 20005-3922.This standard was processed and approved for
