2、uncilApproved 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 ATA interface is defined in the ATA/ATAPI
3、-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) Coordinated shared use of Serial ATA devices
4、 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 to existing Serial ATA standards and no ch
5、anges 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 incorporated in systems that take advantage of t
6、his standard.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 established when, in the judgement of the ANSI Board ofStandards Review, substantial ag
7、reement 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 considered, and that a concerted effort be madetowards their resolution.The use of Ame
