4、iat Information Technology Industry Council Approved September 28, 2007 American National Standards Institute, Inc. Abstract This amendment to ANSI INCITS 374-2003, Information Technology - Fibre Channel - Fibre Channel Single-Byte Command Set-3 (FC-SB-3), describes persistent IU pacing, a method fo
5、r allowing an FC- SB-3 channel to retain a pacing count that can be used at the start of execution of a channel program. This may improve performance of long I/O programs at higher link speeds and long distances by allowing the Channel to send more IUs to the control unit and eliminating the delay o
6、f waiting for the first Command Response. This amendment augments, but does not replace, existing Fibre Channel standards.

7、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 standards developer. Consensus is established when, in th
8、e 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 requires that all views and objections be considered, and th
9、at 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, marketing, purchasing, or using products, processes, or p
10、rocedures 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 authority to issue an interpretation of an American Natio
11、nal 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 CAUTION NOTICE: This American National Standard may be revised or withdrawn at any time. The pr
12、ocedures 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 or writing the American National Standards Institute.

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