VSO Minutes, Wednesday,
January 22, 2003
Hyatt Regency Ð Long
Beach
Call to Order
Elwood Parsons called
the meeting to order at 9:00 AM and asked members to introduce themselves. After introductions the minutes from
the November 2002 VSO meeting were approved as written. The agenda
for the current meeting was reviewed and accepted.
Standards Report
John Rynearson, VITA,
gave the standards report. See presentation.
VITA Europe Report
Hermann Strass, VITA
Europe, gave a report on European activities. See presentation. Hermann also presented his concept for
ÒSerial VMEÓ. See presentation. After discussion a list for a
study group was circulated.
*** BREAK ***
ANSI Patent Policy and
Call for Patents
John Rynearson stated
the ANSI patent policy and the VSO early disclosure patent policy. See
presentation. A call for
patent disclosures was made. No
patents were disclosed.
John presented the
requirements for complying with ANSIÕs and VSOÕs patent policy and discussed
the reasons for these policies. See presentation. John discussed with the membership
recent patent issues concerning the connector chosen for VITA 34.

VITA 41 Report
Bob Tufford, Motorola,
reported on the status of VITA 41.
See presentation.
Andreas Lenkisch,
Schroff, presented the routing study for VITA 41. See presentation.
Bob Tufford discussed
the next steps for VITA 41. Issues
discussed include user I/O and transition modules, system management, common
user I/O keying, stiffeners, and LED positions.
Jim Koser, Foxconn
Electronics, raised the issue of
providing rear connectors and how that would be done. He stated that there was a Teradyne patent covering the
technique of inserting front and rear connectors into common backplane
holes. Jim offered to try to find
the specific patent.
One of the attendees
asked a question about putting 3.3 volts on switch cards. Bob indicated that there are no plans
to add 3.3 volts to the switch card.
David Pepper, VMIC,
asked if anyone was interested in doing gigabit Ethernet on VXS. No one has signed up to champion this
effort, but many members agreed it would be a good idea.
The group discussed
whether VXS might accommodate conduction cooled boards.
VITA 34
Frank Hom gave an update
on VITA 34. See presentation.
Frank discussed the ZD
connector issue. The group
discussed various options.
A motion was made to
rescind the data connector selected at the March 2000 VSO meeting for VITA 34
and to resume the data connector selection process at the point prior to the
vote, and to send a letter to Teradyne explaining the actions of the VSO regarding
this matter and to give Teradyne 30 days to respond by providing a letter
indicating TeradyneÕs willingness to provide RAND terms for any patents it
claims against the HM Zd connector.
The motion was seconded.
John Rynearson reviewed the VSO policy for rescinding a working group
decision. It was determined that
in this instance only a simple majority vote was required. Further discussion
regarding the motion was held. A
vote on the motion was taken and the motion passed with 21 votes in favor and 3
votes against.
The membership directed
the VITA executive director and the technical director to write and send the
letter to Teradyne.
The membership directed
that a second call for prior art on US patent no. 6,379,188
be carried out.
Frank reviewed quick
disconnect options. The goal is to
define a common interface short of the actual coupler. The actual coupler will have to be
specified by the user.
Frank discussed the
cooling demo that was shown at the Bus&Board conference. Frank said plans are to continue to
refine the demo.
VITA 34 Cooling Team
Larry Thompson, CRANE,
made a announcement that the joint cooling task group will have a meeting on
Tuesday before the May VSO meeting.
More details will be provided at the March meeting.
*** BREAK ****
VITA 34 Mil/Cots Study
Group
Mike Macpherson gave a
report on the groups activities. See presentation.
Jim Robles, Boeing,
reported on ESD requirements. See exhibit.
Jim reviewed IO modules and racks.
See exhibit. The group discussed various form factors options: 6U x 160
versus 4U x 220mm. The general
consensus is that 6U is preferred by the mil/cots. Mike Macpherson would like mil/cots study group to meet on
Thursday to discuss the form factor issue.
VITA 42
Greg Novak, Motorola,
reviewed the status of the VITA 42 working group. See presentation.
Greg discussed the RAPIDIO PMC form factor. The standard PMC connector tops out around 1 Ghz.
Doug Wathen, Samtec,
discussed the connector that was chosen by the RapidIO Trade Association. Doug indicated that Samtec was willing
to provide VITA with a letter stating its willingness to license the connector
on RAND terms.
A sample of the
connector was circulated. Doug
also referred to a lawsuit currently ongoing by FCI against Samtec. He said that he expects the lawsuit to
be settled soon.
Greg discussed how the
standard will be structured. The
RapidIO document was reviewed. One
of the challenges will be to limit and combine various options.
Mac Rush, Motorola,
raised the issue of the purpose of the VITA 42 spec versus the RapidIO
specification. Why should there be
two specifications for the same thing.
One reason is that the VITA 42 group wants to use other fabrics besides
RapidIO.
Greg discussed the
schedule. The first work effort
will be VITA 42.0. Greg discussed
the next series of conference calls.
Greg will solicit times via email.
The goal is to have a draft .0 before the March VSO meeting.
VITA 43S
Michael Franco, Artesyn,
discussed interest in Z-axis modules.
Mike reviewed the effort in PICMG.
Mike will circulate a white paper on his concept and ask for input. A sign-up sheet
was circulated.
Elwood Parsons adjourned
the meeting at 5:45 PM.
Thursday, January 23,
2003
Elwood Parsons called
the meeting to order at 8:30 AM.
The agenda was changed to allow
for a VITA 34 mil/cots study group discussion.
Mike Macpherson led a
discussion on the board size issue.
One of the reasons for wanting a larger board was because of the need
for on-board power converters, larger microprocessors, and space for more
functionality. The group discussed
how a 4U x 220 mm module could be inserted with a different wedge lock
mechanism.
Harry Andreas noted that
commercial boards are often used in military programs for prototyping and
software development.
The group discussed
alternate cooling (liquid flow) concepts.
The discussion returned
to board size advantages Ð 6U versus 8U.
Bob Downing made a drawing showing 6U laid on
top of 8U. The 6U would not
necessarily be usable in an 8U
commercial rack. Bob asked the
question as to whether or not half sized (i.e., 4U) in 8U is a requirement.
A motion was made and
seconded to develop two form factors for VITA 34. After discussion the motion passed. The next step will be to determine
which form factors.
VITA 40, Service
Indicator Standard
Danny Cohen, Sun,
reviewed comments from the recent
working group ballot. The results
of the ballot were: 18 approve, 0 negative, 4 no return. VITA 40 has met the 75/75 VSO rule and
will be moved to the ANSI process.

Other Business
Danny Cohen, Sun, asked
that formal motions be presented in writing on the computer projector so that
members could better understand the motion.
John Rynearson reviewed
the meeting schedule for 2003. See
VITA website.
Elections for Chair and
Vice Chair of the VSO will be held
John Rynearson asked
Mike Macpherson and Mike Thompson to serve with him on the nominations committee
for the March VSO elections.
There being no further
business the meeting was adjourned.
