This is T11 document T11/14-018v3 Project T11/2238-D Rev 1.10 Draft Proposed American National Standard for Information Technology – Fibre Channel – Framing and Signaling - 4 (FC-FS-4) 1 Scope This standard describes the framing and signaling interface of a high performance serial link for support of FC-4s associated with upper level protocols (e.g., SCSI, IP, SBCCS, VI). This standard is based on FC-FS-3 (ANSI INCITS 470-2011) with subsequent modifications approved by the member body that originally authored and approved FC-FS-3. The following Fibre Channel features specified in FC-FS-3 are obsolete in this standard: Feature 1 Project T11/2238-D Rev 1.10 This is T11 document T11/14-018v3 2 References 2.1 Qualification and availability of references The references listed in this clause contain provisions that, through reference in this text, constitute provi- sions of this document. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the standards listed in this clause. Orders for ISO Standards and ISO publications should normally be addressed to the ISO member in your country. If that is impractical, ISO Standards and ISO publications may be ordered from ISO Central Secre- tariat (ISO/CS): Phone +41 22 749 01 11 Fax +41 22 749 09 47 E-mail [email protected] Post ISO, 1, ch. de la Voie-Creuse, CH-1211 Geneva 20, Switzerland In order to avoid delivery errors, it is important that you accurately quote the standard's reference number given in the ISO catalogue. For standards published in several parts, you should specify the number(s) of the required part(s). If not, all parts of the standard will be provided. Copies of the following documents may be obtained from ANSI, an ISO member organization: Approved ANSI standards; approved international and regional standards (ISO and IEC); and approved foreign standards (including JIS and DIN).
