Implementation Guide

By Editor on Dec 11, 2012

The following table features links to transport protocol and command set specifications that affect the building of various products (e.g., SSDs):

To BuildTransport ProtocolCommands
SSD SCSI Over PCI Express (SOP)
— and —
PCI Express Queuing Interface (PQI)
(lower level hardware specs for reference)


SAS Protocol Layer (SPL)
— and —
Serial Attached SCSI (SAS)


Fibre Channel Protocol for SCSI (FCP)
( Fibre Channel Fabric standards,
especially FC-FS and FC-LS)



USB Attached SCSI (UAS)
Universal Serial Bus Specification
SCSI Primary Commands (SPC)
— and —
SCSI Block Commands (SBC)

All SCSI standards rely upon the SCSI Architecture Model (SAM) for foundation principles and requirements.

References for lower level hardware specs — none needed for SAS

For PCI:
PCI Express Base Specification —
PCI Local Bus Specification —
PCI Bus Power Management Interface Specification —
PCI Express Card Electromechanical Specification —
