2、mation Technology AT Attachment with Packet Interface - 7Volume 3 - Serial Transport Protocolsand Physical Interconnect(ATA/ATAPI-7 V3)SecretariatInformation Technology Industry CouncilApproved February 7, 2005 American National Standards Institute, Inc.AbstractThis standard specifies the AT Attachm
3、ent Interface between host systems and storage devices. It pro-vides a common attachment interface for systems manufacturers, system integrators, software suppliers,and suppliers of intelligent storage devices. It includes the Packet Command feature set implemented bydevices commonly known as ATAPI
4、devices. It also includes the Serial Transport Protocols and PhysicalInterconnect for AT Atachment devices commonly known as Serial ATA.This standard maintains a high degree of compatibility with the AT Attachment Interface with Packet Inter-face - 6 (ATA/ATAPI-6), ANSI INCITS 361-2002, and while pr
5、oviding additional functions, is not intendedto require changes to presently installed devices or existing software.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 develop
6、er.Consensus is established 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 a
7、nd objections be 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
8、usingproducts, processes, 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 aninterpret
9、ation of an American 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 orwithdraw
10、n at any time. The procedures of the American National StandardsInstitute require that action be taken periodically to reaffirm, revise, orwithdraw this standard.
