29、mmand set for magnetic tape drives (IPI-3 tape) FOREWORD 1) ISO (International Organization for Standardization) and IEC (International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the developmen
30、t of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental,
31、in liaison with ISO and IEC, also take part in the work. 2) In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publicatio
32、n as an International Standard requires approval by at least 75 % of the national bodies casting a vote. 3) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying an
33、y or all such patent rights. International Standard ISO/IEC 9318-4 was prepared by subcommittee 25: Interconnection of information technology equipment, of ISO/IEC joint technical committee 1: Information technology. This second edition cancels and replaces the first edition published in 1990, and c
34、onstitutes a technical revision. The following items have been added or changed since the first edition: - revised scope; - attribute usage was added (subclause 4.10, subsequent clauses were renumbered); - addition of new parameters for position control command (subclause 7.2). ISO/IEC 9318-4 comple
35、ments other Intelligent Peripheral Interface standards. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.9318-4 ISO/IEC:2002(E) 9 INTRODUCTION This standard provides a definition of the device-generic command set portion of a series of standards called the Intellig
36、ent Peripheral Interface (IPI), a high performance, general- purpose parallel peripheral interface. This standard responds to an industry market need (expressed both by users and manufacturers) to limit the increasing costs in hosts associated with changes in peripherals. The first five clauses of t
37、his standard contain material that is useful across all classes of device that the device-generic command sets can support. Clauses 6 to 12 are oriented to particular device classes and in this document these clauses are intended for use with Magnetic Tape Drives. Clause 1 describes the scope. Claus
38、e 2 lists the normative references. Clause 3 provides descriptions of conventions. Clause 4 describes the Environment of Use and projected application areas. Clause 5 describes the Message Packet structure used for commands and responses. Clause 6 describes Control commands. Clause 7 describes Posit
39、ion commands. Clause 8 describes the most generic Transfer commands. Clause 9 describes the Combination Transfer commands, which require a minimum of two sets of extents. Clause 10 describes the other Transfer commands, which are more device specific than those in clause 8. Clause 11 describes the D
40、iagnostic commands. Clause 12 summarizes the commands defined in the document. Annex A gives an overview of interface levels and concepts. 10 9318-4 ISO/IEC:2002(E) INFORMATION TECHNOLOGY INTELLIGENT PERIPHERAL INTERFACE Part 4: Device generic command set for magnetic tape drives (IPI-3 tape) 1 Scop
41、e This part of ISO/IEC 9318 describes the logical level (generic level) interface for tape drives and it provides a definition of the device-generic portion of a family of standards called the Intelligent Peripheral Interface (IPI). The purpose of this standard is to facilitate the development and u
42、tilization of an intelligent interface which permits the interconnection of multiple peripheral types such as disk, tape and communications to a controller. The intent of the IPI is to isolate the host (CPU), both hardware and software, from changes in peripherals by providing a “function-generic“ c
43、ommand set to allow the connection of multiple types of peripherals (disks, printers, tapes, communications). To smooth the transition from the current methods to the generic approach, the IPI supports device-specific command sets to aid in bridging the gap between the two approaches. To accomplish
44、this set of goals, the design of the IPI includes device-specific and device- generic command sets. The device-specific command set provides: device-oriented control; physical data addressing; timing critical operations; lower device cost. The device-generic command set provides a higher level of fu
45、nctionality and portability. It includes: host/device independence; logical data addressing; timing independence; command queuing capability. A system is not restricted to the use of one level of command set or the other. It is possible that both levels of command sets will be utilized with a given
46、systems architecture to balance such parameters as system performance, cost and peripheral availability. It is also possible for the host to provide for the migration from device-specific to device-generic levels while still retaining the same physical interface. The IPI standards family includes th
47、e definition of a high performance, general-purpose parallel peripheral interface. However, the device-generic command set may also be transported over other non-IPI physical interfaces. ANSI X3.291:1997 contains “mappings“ to the High-Performance Parallel Interface (HIPPI) and Fibre Channel (FC) as
48、 well as to the IPI Enhanced Physical Interface. The “mappings“ are not contained in this document.9318-4 ISO/IEC:2002(E) 11 2 Normative references The following referenced documents are indispensable for the application of this document.
