3、 IHS -,-,- INCITS 437-2008 American National Standard for Information Technology Fibre Channel SATA Tunneling Protocol (FC-SATA) Secretariat Information Technology Industry Council Approved December 19, 2008 American National Standards Institute, Inc. Abstract This standard specifies a Fibre Channel
4、 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-7 set of standards (ANSI INCITS 397-2005). This standard specifies: a)Efficient transport of Serial ATA commands and res
5、ponses 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 by multiple host systems on any Fibre Channel topology; d)Discovery of Serial ATA devices attached to any Fibre Channel
6、 topology; and e)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 changes to existing Fibre Channel standards other than nominal changes necessary for addition of a new FC-4. This standar
7、d 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 this standard.

8、oring/1111111164 Not for Resale, 04/06/2009 02:39:08 MDTNo reproduction or networking permitted without license from IHS -,-,- Approval of an American National Standard requires review by ANSI that the requirements for due process, consensus, and other criteria for approval have been met by the stan
9、dards developer. Consensus is established when, in the judgement of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus require
10、s that all views and objections be considered, and that a concerted effort be made towards their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the standards or not, from manufacturing, mark
11、eting, purchasing, or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreover, no person shall have the right or auth
12、ority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard. CAUTION NOTICE: This American National Sta
13、ndard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard. Purchasers of American National Standards may receive current information on all standards by calling o

By publication of this standard, no position is taken with respect to the validity of this claim or of any rights in connection therewith. The known patent ho
