Call VSO meeting to order Introductions, Agenda Review Announcements, Minutes Approval |
Elwood Parsons, VSO Chair |
The meeting of the VSO was opened at 8:00am on May 18,
2005 by chair Elwood Parsons of Foxconn. Individual introductions were made and the
agenda reviewed. Minutes of
the March meeting were approved by acclimation after a motion to approve
by Andy Reddig and a second by Danny Cohen. |

Call
for Patent Disclosures |
Elwood Parson, Chair |
A statement regarding patent policy was given by the
chair and a request for intellectual property disclosures was responded to
by Rex Harvey of Parker Hannifin who stated that they had applied for a
patent on the dual purpose alignment pin/quick disconnect device being
considered for use in VITA 48.
The patent is pending and Parker Hannifin will RAND license
the technology. |

Platform Mgmt Proposal |
Ken Boyette, Critia |
(Presentation) The VITA Standards Organization
meetings were started by a presentation on a platform management
architecture proposal by Ken Boyette of Critia Computers. The original VSO specification on
this subject was ANSI VITA 38,
VITA 41 has inherited this work and VITA 46 is now
actively investigating how and to what degree IPNE adds benefits and at
what cost in real estate and cost per unit. VITA 48 will drive enhanced environmental monitoring
will need to utilize this technology to a greater degree. AMD has just publicly introduced
the Open Platform Management Architecture Specification (OPMA) which
builds on the IPMI foundation.
This was developed specifically for the server market. It provides IPMI based platform
management using SODIMM socket technology. There are 4 option levels and supports new IPMI technology
(serial over LAN, keyboard video mouse over IP). Ken is proposing a standard in the
form of a mezzanine card using the AMD devices to provide an embedded
centric mix of sensor and control signals for system monitoring and
maintenance. This could be
used on VME, VITA 42 or 46 and other boards and could be used on an as
needed basis either initially, later or selectively on these
systems. A sign-up
sheet was circulated to start a new group and received sufficient
sponsor level supporters to become a VSO working group. This is being titled
"EPMA Platform Management Architecture". |

VITA 17.2, 10 Gbit Serial FPDP Report |
Dean Holman, Mercury |
VITA 17.2 – 10Gbit Serial Front Panel Data
Port– Dean Holman of Mercury reported that the group is holding
bi-weekly teleconferences and has decided to break out the 10 Gbaud
portion into a future dot specification. Anyone interested in joining
this group is to contact John Rynearson to be added to the reflector. |

VITA 41, VXS Report |
Bob Tufford, Motorola |
VITA 41 –VXS (Presentation)
VITA 41.0, 41.1, 41.2 and 41.10 have been finalized per the VSO process and
have been stable for some time and will be submitted for ANSI balloting per
Bob Tufford of Motorola. VITA 41.11 (RearTransition Module) has been the focus of
the working group for the last two months and version 0.65 is in working
group ballot. Plans/schedule for ANSI balloting include: VITA 41.0
(Base Spec), 41.1 (Infiniband), 41.2 (Serial Rapid I/O), and 41.10 (Live
Insertion) are to be submitted for ANSI balloting within a month. VITA 41.3 (Gigabit Ethernet) and 41.4 (PCI Express) are
to be sent to ANSI within 3 months.
VITA 41.11 (Rear Transition Module) is to be forwarded to ANSI within
6 months. Andy Reddig of Tekmicro proposed another dot
specification in the VITA 41 family. (See Presentation). This is a protocol specification
similar to the .1, .2, etc. which will add Xilinx Aurora protocol. A sign-up
sheet was circulated to start a new group and received sufficient sponsor
level supporters to become a VSO working group. This is being titled "Protocol Specification:
Aurora" and will be numbered VITA 41.5. |

VITA 42, XMC Update |
Andy Reddig, Tekmicro |
VITA 42 – XMC (Presentation) This subcommittee is struggling with
a connector issue. Samtec proposed at the last meeting that the current
version be replaced with an improved connector. This has raised concerns centered
on performance (environmental testing, etc.), IP conflicts, and
schedule impact. The group
will be deciding whether to use the current connector as is, modify the
current connector or use the "improved" connector with
the associated schedule impact.
Of note is that several companies are currently building product to
the standard as written. Andy
Reddig of Tekmicro substituted for chair Greg Novak and conducted a
straw poll of the VSO as a whole which showed no support for continuing
with the specification with the current connector. Instead the group was divided into
two factions who wanted to proceed with the standard as
currently written with the anticipation of connector improvements (to
the current connector) or those who wanted to delay the specification
until the modifications to the current connector are completed and
tested. There was no
support for the new Samtec connector or for restarting the standard
with a totally new connector.
There is a final decision scheduled for the VITA 42 working group
meeting scheduled for Thursday morning. A new sublevel specification (VITA 42.5 – Xilinx
Aurora Protocol) was proposed by Andy Reddig of Tekmicro and a sign-up sheet circulated to start a new
group and received sufficient sponsor level supporters to become a VSO
working group. This is being
titled "Xilinx Aurora Protocol" and will be numbered VITA
42.5. |

VITA 46, VPX Status Report |
Stewart Dewar, Curtiss-Wright |
VITA 46 – VPX (Presentation)
Stewart Dewar of Curtiss Wright gave the VITA 46 committee update. VITA 46.10 (Rear Transition Module)
has had the concept defined but the first draft has not yet been
written. This is underway. There is also an effort to
record and control the keying definitions and combinations for VITA 46
plug-in modules and backplanes.
This will be VITA 46.12 and there will be a preliminary draft by
the end of May. Open
issues for VITA 46 include the availability of 50 micro inch gold plated
contacts and the associated cost impact, plating options for the
alignment/guide pins and the current rating of the power wafer
contacts. Final testing
of the MultiGig connectors is in process with a modified salt fog and
SO2 environmental test program.
The final test report is anticipated in 2 to 3 weeks. Lastly, the group is working on the
extent and complexity of electrical modeling and simulation that needs
to be done. |

VITA 48, ERDI |
Randy Banton, Mercury Computer |
VITA 48 – ERDI (Presentation) Randy Banton of Mercury
Computers gave the VITA 48 update. VITA 48.0 (Base specification), .1
(Air and Conduction Cooled) and .2 (Liquid Flow Through) drafts have
been published, although a vote was taken to split the air and
conduction cooled dot specification into two documents. Current work involves discussion of
alignment and tolerances, two level maintenance, and integration of a
combination quick disconnect/guidance mechanism. A section has been added to the
document listing essential and nonessential patents in an effort to
clarify the topic. There
have been no new patents or IP issues added in this listing. Richard
Hodges and Rex Harvey of Parker Hannifin showed examples of the
new quick disconnect/guide pins. |

|
VITA 49, Digital IF |
|
VITA 49 – Digital IF – Randy Banton of
Mercury informed the group that the Digital IF working group is holding
weekly telecons, occasional face to face meetings and are making
progress on their standard. The
group is planning to attend the July meeting and give a tutorial and
status report on the work to date. |
|||
|
VITA 50, Cooling |
Rex Harvey, Parker Hannifin |
VITA 50 – Cooling – Rex Harvey outlined the
work to date. The group is developing
a handbook or manual to describe the various methods of
cooling electronic devices.
This will be a "what can be done, not how to do
it" document. An
outline has been developed and work is proceeding on the first draft. |

|
VITA 51, Reliability Prediction |
Lori Bechtold, Boeing |
VITA 51 – Reliability Prediction (Presentation) Lori Bechtold from Boeing
updated the VSO on the work to date. There have been several fact finding
and organizational telecons since the last VSO meeting and VITA 51 has
decided to hold a full working group meeting in conjunction with the
July VSO meeting. They are
developing their charter and have established four subgroups – WG1
will develop the charter, WG2 is responsible for document development,
WG3 is working on certification and control mechanisms, and WG4 is
responsible for promotion of the effort. |
