4、ndards Institute, Inc. Abstract This standard describes the frame format and protocol definitions required to transfer commands and data between a SCSI (Small Computer System Interface) initiator and target using the Fibre Channel family of standards. The second version (ANSI INCITS 350) added optio
5、nal retransmission, task ordering, and con- firmation capabilities. This third version incorporates bi-directional commands, removes information that is now contained in other standards, and describes additional error recovery capabilities for the Fibre Channel Protocol.

7、e requirements for due process, consensus, and other criteria for approval have been met by the standards 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. Substantia
8、l agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires 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
9、 any respect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, 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 a
10、n interpretation of any American National Standard. Moreover, no person shall have the right or authority 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 spons
11、or whose name appears on the title page of this standard. CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time.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. Pur
12、chasers of American National Standards may receive current information on all standards by calling or writing the American National Standards Institute.

14、 The developers of this standard have 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, if any, patent
15、s may apply to this standard. As of the date of publication of this standard, following calls 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 position is taken with
16、 respect to the validity of this claim or of any rights in connection therewith. The known patent holder(s) has (have), however, filed a statement of willingness to grant a license under these rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to ob- tain such a l
17、icense. Details may be obtained from the publisher. No further patent search is con- ducted by the developer or publisher in respect to any standard it processes. No representation is made or implied that this is the only license that may be required to avoid infringement in the use of this standard
