`
`Abstract
`I/O bus with up to 16 devices,
`to provide an efficient peer-to-peer
`is designed
`The SCSI protocol
`including one or more hosts. Data may be transferred asynchronously
`at rates that only depend
`on device implementation and cable length. Synchronous data transfers are supported at rates up
`to 10 mega-transfers per second. With the 32-bit wide data transfer option, data rates of up to 40
`megabytes per second are possible.
`SCSI-2
`includes command sets for magnetic and optical disks, tapes, printers, processors, CD-
`ROMs, scanners, medium changers, and communications devices.

`
`American
`National
`Standard
`
`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 the judgment 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 that a concerted effort be made toward 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 procedures 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 National 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`withdrawn at any time.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 procedures 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.
`
`CAUTION: The developers of this standard have requested that holders of patents that may be required for the
`implementation of the standard disclose such patents to the publisher. However, neither the developers nor the publisher
`have undertaken a patent search in order to identify which, if any, patents may apply to this standard. As of the date of
`publication of this standard and following calls for the identification of patents that may be required for the implementation
`of the standard, no such claims have been made. No further patent search is conducted by the developer or publisher in
`respect to any standard it processes. No representation is made or implied that licenses are not required to avoid
`infringement in the use of this standard.
