标准摘要
[中文适用范围]： 该国际标准定义了 SCSI 存储阵列设备的命令集扩展；通常称为 RAID 设备。 该标准主要旨在与任何 SCSI 命令标准或 SCSI-3 体系结构模型 (ISO/IEC 14776-411) 标准结合使用，而不是替代任何标准。 该国际标准旨在替代 SCSI-3 控制器命令 (ISO/IEC 14776-341) 标准。 生成的命令有利于 SCSI 存储阵列的控制和配置，从而为 SCSI 存储阵列设备的系统集成商和供应商提供通用命令规范。 该国际标准包含 SCSI-3 控制器命令 (ISO/IEC 14776-341) 标准中定义的所有信息。 此外，该国际标准还规定了新的命令和扩展的模型条款。 本标准中与 SCSI 存储阵列设备类别相关的条款，与任何 SCSI 命令标准中的适用条款一起实施，应指定可用于 SCSI 存储阵列的标准命令集。 SCSI 控制器命令的目标是提供以下内容： a) 传输 SCSI 控制器命令设备特有的命令； b) 管理 SCSI 控制器命令设备操作的控制命令； c) 可选的设备映射和直通支持。 [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 should properly coordinate their actions or data corruption will result. This standard defines commands that assist with coordination between multiple operating systems. This standard defines a device model for SCSI storage arrays, commonly known as RAID devices. This standard defines the SCSI commands that may apply to SCSI storage arrays and the SCSI commands that are uniquely for SCSI storage arrays. It is intended to be the choice for new designs over the original SCSI-3 Controller Commands (SCC) standard. Several new high level service actions have been added to this standard that simplify configurations.
