This page includes the T10 working draft documents. There are no approved (official) standards here. Once a standard is approved, you should buy it from ANSI (+1-212-642-4900). Your payment insures that you receive the actual standard with all the final changes and it supports the standards process. In most cases, the final T10 committee working draft revision for a project is retained here. The drafts are used by T10 Committee members for reference. In case of any conflict, the published ANSI standard prevails.
Disclaimer: While it is intended that the documents listed here are at the latest committee revision level, there may be some delays in posting drafts here. Also, draft documents are not completed standards. The T10 Technical Committee may modify these documents as a result of its development activities. Any use of information contained in these documents is at your own risk.
This page is organized as follows:
Note that the original third-generation SCSI standards used the name SCSI-3 to distinguish them from SCSI-2. Subsequent SCSI standards have dropped the '-3' from their names because it was cumbersome. So, when the SCSI-3 Architecture Model (SAM) was revised, it became the SCSI Architecture Model - 2 (SAM-2). While the individual components of the SCSI family continue to evolve, there is no SCSI-4 project envisioned.

Included File: sas2r14c.zip (3954886 bytes)
The Serial Attached SCSI - 2 (SAS-2) draft standard is the second generation of SAS, which adds an option for a 6 Gb/sec link speed. It is based upon SAS-1.1. It continues to document both a physical Layer that is compatible with Serial ATA and protocols for transporting SCSI commands to SAS devices and for transporting ATA commands to SATA devices.
Beginning with SAS-2.1, the protocol layer is separated into its own standard, called SAS Protocol Layer (SPL). It is anticipated that eventually there will be follow-on standards called: SPL-1, SPL-2, etc.
SAS Protocol Layer (SPL)
{Date: not available yet, Status: Development, Project: 2124-D}
The SAS Protocol Layer (SPL) standard documents the SAS protocol layer corresponding to the Serial Attached SCSI - 2.1 (SAS-2.1) and beyond. Prior to this standard, the protocol layer was included with the physical layer. This standard adds enhancements to reduce congestion in the SAS topology and to support interface power management.
Serial Attached SCSI - 2.1 (SAS-2.1)
{Date: not available yet, Status: Development, Project: 2125-D}
The Serial Attached SCSI - 2.1 (SAS-2.1) draft standard defines a number of incremental enhancements to the SAS-2 standard, including active cables, additional connectors, and power management.
