ABSTRACT
This standard specifies the functional requirements for the Serial Attached SCSI (SAS) physical interconnect,
which is compatible with the Serial ATA physical interconnect. This standard is intended to be used in
conjunction with SCSI and ATA command set standards.

Standard
Approval of an American National Standard requires verification by ANSI that the
requirements for due process, consensus, and other criteria for approval have been met by
the standards developer. Consensus is established when, in the judgment of the ANSI Board
of Standards Review, substantial agreement has been reached by directly and materially
affected interests. Substantial agreement means much more than a simple majority, but not
necessarily unanimity. Consensus requires that all views and objections be considered, and
that effort be made towards their resolution.
The use of American National Standards is completely voluntary; their existence does not in
any respect preclude anyone, whether he has approved the standards or not, from
manufacturing, marketing, purchasing, or using products, processes, or procedures not
conforming to the standards.
The American National Standards Institute does not develop standards and will in no
circumstances give interpretation on any American National Standard. Moreover, no person
shall have the right or authority to issue an interpretation of an American National Standard
in the name of the American National Standards Institute. Requests for interpretations
should be addressed to the secretariat or sponsor whose name appears on the title page of
this standard.
CAUTION NOTICE: This American National Standard may be revised or withdrawn at any
time. The procedures of the American National Standards Institute require that action be
taken periodically to reaffirm, revise, or withdraw this standard. Purchasers of American
National Standards may receive current information on all standards by calling or writing the
American National Standards Institute.
CAUTION: The developers of this standard have requested that holders of patents that
may be required for the implementation of the standard, disclose such patents to the
publisher. However, neither the developers nor the publisher have undertaken a patent
search in order to identify which, if any, patents may apply to this standard.
As of the date of publication of this standard, following calls for the identification of
patents that may be required for the implementation of the standard, notice of one or
more claims has been received.
By publication of this standard, no position is taken with respect to the validity of this
claim or of any rights in connection therewith. The known patent holder(s) has (have),
however, filed a statement of willingness to grant a license under these rights on
reasonable and nondiscriminatory terms and conditions to applicants desiring to obtain
such a license. Details may be obtained from the publisher.
No further patent search is conducted by the developer or the publisher in respect to any
standard it processes. No representation is made or implied that licenses are not
required to avoid infringement in the use of this standard.
