The SCSI Trade Association is not responsible for the technical standards concerning the SCSI specifications. This responsibility rests with the T10 Committee.
T10 is a Technical Committee of the International Committee on Information Technology Standards (INCITS, pronounced “insights”). INCITS is accredited by, and operates under rules that are approved by, the American National Standards Institute (ANSI). These rules are designed to ensure that voluntary standards are developed by the consensus of industry groups.
Please visit the T10 Committee site for the most comprehensive location for past and present documents on the technical specifications for SCSI.
