标准摘要
[中文适用范围]： ISO/IEC 14776 的这一部分定义了命令集扩展，以方便 SCSI 流设备的操作。 该标准与 ANSI INCITS 351-2001 相结合，全面规定了 SCSI 流设备类的标准命令集。 该标准 (SSC) 的目标是提供以下内容： a) 允许应用程序客户端通过 SCSI 服务交付子系统与在设备类型字段中声明自己是顺序访问设备或打印机设备的逻辑单元进行通信INQUIRY命令响应数据； b) 定义每种类型的 SCSI 流设备特有的命令； c) 定义管理SCSI流设备操作的命令； d) 定义 SCSI 流设备类型之间的差异。 图 1 显示了 SCSI 标准的一般结构。 该图并不旨在暗示诸如层次结构、协议栈或系统架构之类的关系。 [外文原描述]： 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). SSC permits SCSI streaming devices such as tape and printer devices to attach to computers and provides the definitions for their use. This standard specifies the external behavior of a device server that defines itself as either a Sequential-access device or a Printer device; together, these device types are known as Stream Devices. The SSC standard conforms to SCSI-3 Architectural Model (ISO/IEC 14776-411:1999) standard.
