3、retariatInformation Technology Industry CouncilApproved December 19, 2008American National Standards Institute, Inc.AbstractThis standard specifies a Fibre Channel mapping layer (i.e., an FC-4) to enable the use of Fibre Channel topologies to attach Serial ATA devices to ATA host systems. The Serial
4、 ATA interface is defined in the ATA/ATAPI-7 set of standards (ANSI INCITS 397-2005).This standard specifies:a) Efficient transport of Serial ATA commands and responses over any Fibre Channel topology;b) Communication of necessary Serial ATA interface conditions over any Fibre Channel topology;c) Co
5、ordinated shared use of Serial ATA devices by multiple host systems on any Fibre Channel topology;d) Discovery of Serial ATA devices attached to any Fibre Channel topology; ande) Concurrent operation with other Fibre Channel FC-4s in the same Fibre Channel topology.This standard requires no changes
6、to existing Serial ATA standards and no changes to existing Fibre Channel standards other than nominal changes necessary for addition of a new FC-4. This standard is suitable for implementation in infrastructure attachment devices, so that existing Serial ATA and Fibre Channel products may be incorp
7、orated in systems that take advantage of this standard.Copyright American National Standards Institute Provided by IHS under license with ANSI Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-Approval of an American National Standard requires review by ANSI that the
8、requirements for due process, consensus, and other criteria for approval havebeen met by the standards developer.Consensus is established when, in the judgement of the ANSI Board ofStandards Review, substantial agreement has been reached by directly andmaterially affected interests. Substantial agre
9、ement means much more thana simple majority, but not necessarily unanimity. Consensus requires that allviews and 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 respec
10、t preclude anyone, whether he has approvedthe standards or not, from manufacturing, marketing, purchasing, or usingproducts, processes, or procedures not conforming to the standards.The American National Standards Institute does not develop standards andwill in no circumstances give an interpretatio
11、n of any American NationalStandard. Moreover, no person shall have the right or authority to issue aninterpretation 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 appea

The procedures of the American National StandardsInstitute require that action be taken periodically to reaffirm, revise, orwithdraw this standard. Purchasers of American Nati

15、e requested that holders of patents that may be re-quired for the implementation of the standard disclose such patents to the publisher. However, nei-ther the developers nor the publisher have undertaken a patent search in order to identify which, ifany, patents may apply to this standard. As of the
16、 date of publication of this standard, followingcalls for the identification of patents that may be required for the implementation of the standard,notice of one or more such claims has been received. By publication of this standard, no positionis taken with respect to the validity of this claim or
17、of any rights in connection therewith. The knownpatent holder(s) has (have), however, filed a statement of willingness to grant a license underthese rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to ob-tain such a license. Details may be obtained from the publ

No representation ismade or implied that this is the only license that may be required to avoid infringement in the use ofthis standard.Copyright American National Standards Institute
