ISO/IEC 14776-263:2018
Information technology — Small computer system interface (SCSI) — Part 263: SAS protocol layer - 3 (SPL-3)
ISO/IEC 14776-263:2018 The SCSI family of standards provides for many different transport protocols that define the rules for exchanging information between different SCSI devices. This document defines the rules for exchanging information between SCSI devices using a serial interconnect. Other SCSI transport protocol standards define the rules for exchanging information between SCSI devices using other interconnects.
