1.   Opening Remarks

Lansing Sloan, the acting CAM Chair, called the meeting to order at
9:07 a.m., Tuesday July 11, 1995.  He thanked Symbios Logic for
hosting the meeting.

As is customary, the people attending introduced themselves and a copy
of the attendance list was circulated.  Copies of the draft agenda and
general information on X3T10 were made available to those attending.

2.   Attendance and Membership

attendance requirements for X3T10 membership.  Study group meetings
are open to any person or organization directly and materially

3.   Approval of Agenda

The following item was added to the agenda:

    6. CAM and Fibre Channel

The agenda was approved as modified.
 

4.   Approval of Minutes

In the absence of any objections, the March 1995 CAM study group
minutes were approved as written.


5.   Support of ATA in CAM

Duncan Penman reported that Bill Dallas (CAM chair) and Kevin Calvert
(Future Domain) were to work off-line on matching CAM to ATA.  However, 
neither Bill or Kevin are present at this meeting, and Duncan was 
unaware of any progress they might have made in their off-line
discussions.


6.   CAM and Fibre Channel

Al Pease described a problem with CAM-2 that he has discovered while
working on a Fibre Channel project.  The problem concerned shared 
use of a Fiber Channel Fabric for both storage component access and
networking access.  Al postulated that the networking layers would
access the Fibre via the CAM SIM.

Ralph countered that the more natural layering would be to have the
CAM SIM act as a interface to the physical network access software.
The result is a software-only SIM.  That would be a very different
construct than the current SIM.  However, the physical network access
software is a more feature-rich interface than the SIM interface.  So,
making the SIM access the network software is easier than making the
SIM interface have all the features required by higher networking
software layers.

The question interrupt vectoring was raised.  Ralph noted that the
physical network access software must be constructed to service
multiple TCP clients.  The software SIM would simply be another 
client for the physical network access software.

The Study Group recommended that these concepts be included in the 
CAM-3 document.


7.   Meeting Schedule

The next meeting of CAM Study Group will be September 12, 1995, in
Bedford, NH at the Sheraton Tara Wayfarer Inn (603-622-3766), hosted
by Digital Equipment Corp.


8.   Adjournment

The meeting was adjourned at 9:49 a.m. on Tuesday July 11, 1995.
