本国际标准定义了SCSI-3存储阵列设备的命令集扩展；通常称为RAID设备。本标准主要旨在与任何SCSI-3命令标准和SCSI-3体系结构模型标准（ISO/IEC is 14776-411）结合使用，而不是作为其替代。生成的命令有助于SCSI-3存储阵列的控制和配置，从而为SCSI-3存储器阵列设备的系统集成商和供应商提供了通用的命令规范。本标准中与SCSI-3存储阵列设备类相关的条款，与任何SCSI中的适用条款一起实施- 3命令标准，应指定可用于SCSI-3存储阵列的标准命令集。SCSI-3控制器命令的目的是提供以下内容:a）传输SCSI-3控制命令设备特有的命令；b） 用于管理SCSI-3控制器命令设备操作的控制命令；c） 可选的设备映射和传递支持。

This International Standard defines the command set extensions for SCSI-3 storage array devices; commonly known as RAID devices. This standard is principally intended to be used in conjunction with, not as an alternate to, any of the SCSI-3 command standards and the SCSI-3 Architecture Model Standard (ISO/IEC IS 14776-411). The resulting commands facilitate the control and configuration of SCSI-3 storage arrays and thus provide a common command specification for both system integrators and suppliers of SCSI-3 storage array devices. The clause(s) of this standard pertaining to the SCSI-3 storage array device class, implemented in conjunction with the applicable clauses within any of the SCSI-3 command standards, shall specify the standard command set available for SCSI-3 storage arrays. The objectives of the SCSI-3 Controller Commands is to provide the following: a) Transfer commands unique to SCSI-3 Controller Command devices; b) Control commands to manage the operation of an SCSI-3 Controller Command device; c) Optional device mapping and pass-through support.
