3、oval 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 agreement has been

4、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 American National St

33、 Model 22viiForeword (This foreword is not part of American National Standard ANSI INCITS 432-2007.)This standard defines an API by which a storage application may perform the func-tions of one or more SCSI Targets or Initiators, and control high-performance com-mand/data forwarding and manipulation

34、 facilities.This standard was developed by Task Group T11 of Accredited Standards Commit-tee INCITS during 2003-2006. The standards approval process started in 2006. Thisdocument includes annexes that are informative and are not considered part of thestandard.Requests for interpretation, suggestions

35、 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 was processed and approved for submittal to ANSI by the InternationalCommitte
