Subject: Proposal for Proposed Project -- ATA3-PH
_________________________________________________________________________
Per the agreement of the ATA Working Group meeting on January 10, 1994, I
am submitting this project proposal as one of four new projects which will
constitute the work on ATA-3 standards. I request that the discusion and,
hopefully, forwarding of these project proposals be accomplished at the
March X3T10 plenary meeting.
Respectfully,
Steve Finch
Chair, ATA Working Group
1. Identification of Proposed Project
1.1 Title: ATA-3 Physical Interface (ATA3-PH)
1.2 Proposer
This project is proposed by the X3T10 Technical Committee. For additional
information, please contact John B. Lohmeyer, X3T10 Chairman, at NCR
Corporation, 3718 N. Rock Rd., Wichita, KS 67226 (Phone: 316-636-8703 FAX:
316-636-8889) or Dal Allan, X3T10 Vice-Chairman at ENDL, 14426 Black Walnut
Court, Saratoga, CA 95070 (Phone: 408-867-6630 Fax: 408-867-2115).
1.3 Date Submitted: January 14, 1994
1.4 Project Type: Development
2. Justification of Proposed Standard or Technical Report
2.1 Needs
The draft standard for AT Attachment has been completed and the draft for
the ATA Extensions (ATA-2) is near completion, but as the popularity of the
interface has increased, its application area has grown outside the
originally intended purpose of direct attachment of small disk drives to
desktop computers.
ATA-3 is needed to continue to broaden the scope and application area of
the ATA interface and to take advantage of the huge installed BIOS (Basic
Input/Output System) base, and software. Support is needed for traditional
HDD devices plus additional devices such as CD-ROM and tape devices. It is
expected that the SCSI-3 command sets can be used for these new device
types. In addition, support is also needed for removable media devices and
expanded number of cabling options. The resulting increase in complexity
has made it desirable to divide the ATA standard into a hiarchical set of
standards, of which the ATA-3 Physical Interface is one.
