| Info provided at NETU indicated that the product should be announced at
DECworld in July. Info also provided indicated that product would be
made available for customers willing to provided testimonial at
DECworld as to how good our FDDI products are. James Marsh, Wndy
Michael, Karen Leonard, Paul Calahan and Alan Raderman are the best
people to talk to. Paul specifically handles adpaters.

| The XMI adapter will be announced in July but not available until the
Oct-Nov timeframe. The Q4 ship program is only for the backbone
products (bridge and concentrator). I doubt you will be able to find an
adapter to use in a benchmark by the end of June, but Paul Callahan is
the person to talk to about it.

52.4 | ask the supercomputer group | AKOV12::PERLMUTTER | | Tue Apr 17 1990 11:08 | 12 |
| don't forget about our drb-11 based cray interconnect solution. i
attended the networked supercomputer session at net u. they gave this
as an example. there is also the emerging HPPI standard to consider in
this environment. We apparently do very well in this networked super
computer environment. some people to contact are:
Harold DUGGAN::HAGER (interconnects)
Bob DUGGAN::STETSON (storage)
Tom DUGGAN::RARICH (Networks and storage)

Possible option here would be to provide the demo under non-diclosure
on the DS5000. That's assuming that your data-management software can
run under Risc Ultrix.
re: .4
I is my understanding from Tom Rarich that the current Cray Gateway
will be retired soon. You might want to check with him before you
propose to a customer.
re: .3
It is my understanding that when the XMI Adapter is available in
Oct-Nov that it will not be supported by VMS. There will be Ultrix
only support. Can someone in Prod Marketing confirm this?
re: .0
I'm VERY interested as to what Cray Product will be used for the
Cray side of the FDDI link. The only candidate that I have found for a
similar need, so far, is NSC/DX and NSC is running a very old version
of SMT (4.7) that is not compatable with our proposed release version.

Dave Gagne from VMS stated in another notes conference (don't remember
which one) that if Phase V was available when the hardware is ready,
the driver will be Phase V. If Phase V is not ready, they are
supposedly committed to providing a Phase IV driver. If could be that
the confusion over when DECnet-VAX/Phase V will be ready is making the
issue less clear.

52.7 | VMS is commited; but dates are not firm | STAR::GAGNE | David Gagne - VMS/DECnet-VAX Dev. | Fri May 18 1990 11:29 | 17 |
| Bryan (.6) is correct. VMS will have support for the DEMFA at about
the time the DEMFA ships. It should be obvious that VMS (just like
ULTRIX) cannot adjust its schedules around the DEMFA. There is just
too much support in any one release to tie it to one item (unless that
item is a VAX 9000).
In reality, the VMS driver for the DEMFA will be a Phase V driver.
If DECnet-VAX Phase V is available at the same time, then you get to
see all the Phase V stuff in the driver. If DECnet-VAX Phase V is not
available at the same time, then you get a driver that kind-of sort-of
looks like a Phase IV Ethernet driver; and DECnet-VAX Phase IV will
use that driver.
With my limited knowledge of the DEMFA and VMS schedules, I expect that
the VMS schedule is not very far from the needs of the DEMFA. Of
course, the schedules will change many times between now and ship
time.

52.8 | fddi/xmi performance
| AIMHI::JJONES | John C. Jones | Wed May 19 1993 08:44 | 6 |
| Does anyone have the performance spec on the demfa
yet? Are we saying expect XMI bus speed?
Thanks for the help,
John

| In the Digital technical Journal Summer 1991 Volume 3 Number 3 was an article
called �Peformance Analysis of a High-speed FDDI Adapter� (the DEMFA).
p/n EY-H890E-DP
There's also the article �Peformance of FDDI-Based VAXcluster Systems� in the
VAXcluster Systems Quorum February 1992.

52.10 | Lab versus Real Life | FLUKES::SUTTON | He roams the seas in freedom... | Fri May 21 1993 08:10 | 6 |
| Understand, though, that the figures in that Technical Journal article
were derived in a laboratory environment. Real-life performance will
probably be significantly less than quoted in that article, and will
vary depending on your configuration and network load.
