SCSI系列标准提供了许多不同的传输协议。SCSI传输协议 标准定义了使用互连在SCSI设备之间交换信息的规则。ISO/IEC 14776的这一部分定义了使用 串行连接SCSI（SAS）互连，与串行ATA（SATA）物理接口兼容 互联。它还指定了三种传输协议，一种传输SCSI命令，另一种传输SCSI命令 串行ATA命令用于多个SATA设备，第三个用于支持接口管理。

The SCSI family of standards provides for many different transport protocols. The SCSI transfer protocol standards define the rules for exchanging information between SCSI devices using interconnects. This part of ISO/IEC 14776 defines the rules for exchanging information between SCSI devices using the Serial Attached SCSI (SAS) interconnect, which is compatible with the Serial ATA (SATA) physical interconnect. It also specifies three transport protocols, one to transport SCSI commands, another to transport Serial ATA commands to multiple SATA devices, and a third one to support interface management.
