HIPPI 6400 Mbit/s Physical Layer
( HIPPI-6400-PH)
(HIPPI-6400 is also commercially known as GSN.)
HIPPI-6400-PH, draft amendment in pdf formatAdded an updated maintainence copy of the HIPPI-6400-PH standard and the matching draft amendment, dated March 12, 2001. It will be reviewed April 11, 2001 in Toronto, ON.
HIPPI-6400-PH, revision 2.8Added an updated maintainence copy of the HIPPI-6400-PH standard, dated January 30, 2001. It will be reviewed February 7, 2001 in Huntington Beach, CA.

HIPPI-6400-PH, revision 2.7Added an updated maintainence copy of the HIPPI-6400-PH standard, dated December 1, 2000. This version is the first shot at documenting all the old connector options and at adding the new double stack SCSI type connector. It will be reviewed December 6th, 2000 in Austin, TX.
HIPPI-6400-PH, revision 2.6Three files from Robert Clarkson that provide information on the proposed HIPPI-6400 pinout for the VHDCI double SCSI connector. There's at least one company that may use this information prior to the next meeting, SO PLEASE REVIEW ASAP and comment if you don't like it!
New connector layout in pdf formatEd Cady's charts on a possible new connector for HIPPI-6400. These were presented at the ANSI meeting held in Seattle during August, 2000. (caution- ~5MB file size). I tried to convert this to pdf, but the resulting file size was about 80 MB!

New connector presentation in ppt formatAdded version 2.3B of the HIPPI-6400-PH document in PDF format and a comment response form. This is Don Tolmie's response to the ISO comments. The comment responses lst what has been done to the document. The document is in the ISO format, but is otherwise unchanged from the ANSI version.
Response to HIPPI-6400-PH ISO commentsHere are two testing proposals from FCI-Berg. One of these provides a test plan to resolve the EMI concerns of the cable. The other proposes testing of signal crosstalk.
Draft ISO version of HIPPI-6400-PH
Cross talk testing proposal (pdf)Added an updated HIPPI-6400-PH amendment and maintainence copy of the HIPPI-6400-PH standard, both dated January 23, 2000. These versions have updated connector information and the new grounding scheme to reduce electrical noise.
EMI testing proposal (pdf)
HIPPI-6400-PH, revision 2.5Replaced the previous link with an updated version of the draft amendment (dated June 19, 1999). The update to HIPPI-6400-PH is minor -- using and additional Ethertype when carrying ST traffic with a preceeding fill and length, along with a paragraph reference pointer. The same change is in the draft amendment.
draft amendment for HIPPI-6400-PH
HIPPI-6400-PH Amendment #1 , dated June 19, 1999Added suggested change text (in PDF format) from Joel Darnauer suggesting a change in the HIPPI-6400 cable specification. This suggested change was driven by the FCC testing he is doing.
HIPPI-6400-PH Maintenance Draft, Rev 2.4 , dated June 19, 1999
Updated change pages for HIPPI-6400-PH Rev 2.4 in the form of a draft amendment are here. Replacement pages 24 and 25 change the signal line bit assignments to match SGI's SuMAC implementation. The name of the connector vendor, "Berg", has also been updated to "FCI-Berg". The intent is to process this amendment to HIPPI-6400-PH. Since HIPPI-6400-PH is an approved standard, this can be done in the near future.
These changes became known in September 1998, when HIPPI-6400-PH had almost completed the standardization process. Rather than throw a monkey wrench in the current processing, it was decided to submit these changes as an amendment to the soon to be completed standard. Systems using SuMAC chips should not be affected by the changes. The only known implementation that should have a problem with these changes is the Los Alamos HIPPI-6400 Tester (now discontinued in the current LANL plan).
At least one more meeting will be held before forwarding since there are also some concerns about EMI/RFI that need to be investigated.
HIPPI-6400-PH, rev 2.3, in ISO format, i.e., what will be submitted as draft International Standard ISO/IEC 11518-10 for a DIS letter ballot when the ANSI standard is approved and published.
HIPPI-6400-PH Rev 2.3 (with PDF bookmarks, ANSI front page, ANSI boiler plate, and NCITS membership list) dated July 22, 1998, is here. It contains the changes agreed to at the August '98 Portsmouth, UK, meeting. This is the revision that was forwarded for a final approval and publication as an ANSI standard.
Public Review comment and approved Response, from the August '98, T11.1 and T11 Plenary meetings where the document was forwarded.
Here are some slides presented by Gennum Corp's Bharat Tailor at the October 1999 meeting. These slides provide information about Gennum capabilities that might be useful in a new physical layer.

Status as of November 22, 1999 -
HIPPI-6400-PH was approved as an ANSI standard on 11/20/98. It is now in the ISO fast track process. DIS 11518-10 has been returned from the ISO process (in PDF format) and will be balloted by each member country. T11.1 will vote (12/99 meeting) to provide a recommendation to T11, who in turn must provide a recomendation to the US JTC on how to vote.Document title -
High-Performance Parallel Interface - 6400 Mbit/s Physical Layer (HIPPI-6400-PH)Abstract -
This standard specifies a physical-level, point-to-point, full-duplex, link interface for reliable, flow-controlled, transmission of user data at 6400 Mbit/s, per direction, across distances of up to 1 km. A parallel copper cable interfaces for distances of up to 40 m is specified. Connections to a separate longer-distance optical interface are provided. Small fixed-size micropackets provide an efficient, low-latency, structure for small transfers, and a component for large transfers.Technical Editor -
