2、hnology Industry Council (ITI)Approved November 25, 2002American National Standards Institute, Inc.AbstractThis standard defines the Fibre Channel mapping protocol for the Virtual Interface (VI) Architecture (FC-VI).Approval of an American National Standard requires review by ANSI that therequiremen
3、ts 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 agreement mean
4、s 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 respect preclude
5、 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 interpretation of any A
6、merican 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 appears on the
7、titlepage of this standard.CAUTION NOTICE: This American National Standard may be revised orwithdrawn at any time. The procedures of the American National StandardsInstitute require that action be taken periodically to reaffirm, revise, orwithdraw this standard. Purchasers of American National Stand

Fibre Channel is described in ANSI INCITS 230-1994, Fibre Channel -Physical and Signaling Interface (FC-PH).T
36、his standard was developed by Task Group T11 of Accredited Standards Commit-tee INCITS during 19982001. The standards approval process started in 2001.This standard contains six annexes. Only annex A is normative and is consideredpart of this standard. The rest of the annexes are informative and are
37、 not consideredpart of this standard.Requests for interpretation, suggestions for improvements or addenda, or defect re-ports are welcome. They should be sent to the INCITS Secretariat, Information Tech-nology Industry Council, 1250 Eye Street, NW, Suite 200, Washington, DC 20005-3922.This standard
