Interface standards conformance

The Small Computer System Interface is described in standards including several

versions and a number of individual documents. The original Small Computer

System Interface Standard, X3.131-1986, is referred to herein as SCSI-1. SCSI-1

was revised resulting in the Small Computer System Interface – 2 (X3.131-1994),

referred to herein as SCSI-2. The set of SCSI-3 standards are collectively referred

to as SCSI-3. The applicable SCSI-3 standards are as follows:

SCSI-3 Architecture Model (SAM) X3.270:1996

SCSI Architecture Model - 2 (SAM-2) INCITS.366:2003

SCSI Parallel Interface - 2 (SPI-2) X3.302:1998

SCSI Parallel Interface - 3 (SPI-3) NCITS.336:2000

SCSI-3 Primary Commands (SPC) X3.301:1997

SCSI Primary Commands - 2 (SPC-2) NCITS.351:2001

SCSI-3 Medium Changer Commands (SMC) NCITS.314:1998

SCSI-3 Stream Commands (SSC) NCITS.335.2000

The term SCSI is used wherever it is not necessary to distinguish between the

versions of SCSI.
