2、lApproved December 19, 2008American National Standards Institute, Inc.AbstractThis standard defines an API by which a storage application may perform the functions of one or moreSCSI Targets or Initiators, and control high-performance command/data forwarding and manipulation fa-cilities.Approval of
3、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 reached
4、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 Standards
5、is completely voluntary; theirexistence does not in any respect preclude 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 devel
6、op standards andwill in no circumstances give an interpretation of any American 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 sho

The procedures of the American National StandardsInstitute require that action be taken periodically to reaffirm,
8、 revise, orwithdraw this standard.

However, nei-ther the developers nor the publisher have undertaken a patent search in order to identi
11、fy which, ifany, patents may apply to this standard. As of the date of publication of this standard, followingcalls 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 p
12、ositionis taken with respect to the validity of this claim or of any rights in connection therewith. The knownpatent holder(s) has (have), however, filed a statement of willingness to grant a license underthese rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to
13、 ob-tain such a license. 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.
