标准范围

SCSI命令集旨在通过操作系统对输入/输出设备（磁盘、磁带、打印机等）提供高效的对等操作。SCSI命令集采用命令响应协议。在收到响应之前，对SCSI命令的操作不得视为已完成。响应应包括指示命令最终处置的状态。SCSI命令集提供对一个或多个输入/输出设备的多个操作系统并发控制。但是，多个操作系统必须正确协调它们的操作，否则将导致数据损坏。本标准规定了SCSI的功能要求-3个流命令（SSC）。SSC允许SCSI流设备（如磁带和打印机设备）连接到计算机和提供其使用的定义。本标准规定了设备服务器的外部行为，该服务器将自身定义为顺序存取设备或打印机设备；这些设备类型统称为流设备。SSC标准符合SCSI-3体系结构模型（ISO/IEC 14776-411:1999）标准。

The SCSI command set is designed to provide efficient peer-to-peer operation of input/output devices (disks, tapes, printers, etc.) by an operating system. The SCSI command set assumes a command-response protocol. Action on SCSI commands shall not be deemed completed until a response is received. The response shall include a status that indicates the final disposition of the command.The SCSI command set provides multiple operating systems concurrent control over one or more input/output devices. However, the multiple operating systems must properly coordinate their actions or data corruption will result.This standard specifies functional requirements for SCSI-3 Stream commands (SSC). SSCpermits SCSI streaming devices such as tape and printer devices to attach to computers andprovides the definitions for their use.This standard specifies the external behavior of a device server that defines itself as either aSequential-access device or a Printer device; together, these device types are known as Stream Devices.The SSC standardconforms to SCSI-3 Architectural Model (ISO/IEC 14776-411:1999) standard.
