| 963.1 | I wouldn't call it a "bench mark" - just a bricks demo | JEDI::CAUDILL | Kelly - NaC Tech Support - 264-3320 | Thu May 20 1993 12:23 | 16 |
| No, you were not halucinating. At spring Interop we had a GIGAswitch
and connected to it were two Flamingos (with DEFTA) running OSF/1 and a
dual-process Cobra (with two DEFAAs) running VMS.
There are two, currently seperate, IP performance reports that were
given out at that demo. One is about the results of some performance
improvements made to TCP/IP on DEC OSF/1 AXP. The other is about the
same improvements made to TCP/IP services for OpenVMS AXP (aka UCX V3).
I don't know first hand about either operating system running on any
other alphas, but both OSF/1 on a Flamingo and UCX on VMS on a (even
single processor) Cobra can easily saturate an FDDI with TCP or UDP.
Maybe someone else can post pointers to the reports. Maybe they are
already posted in here somewhere. If not, I have a couple ideas of
people who should be able to post them.

Subject: High Performance TCP/IP for OSF/1 Alpha AXP Workstations (White Paper)
From: ERLANG::DSAP01::hawe "Bill Hawe"
Subj: Alpha/OSF TCP/IP performance paper we are publishing at InterOp this week
Abstract:
Today, Digital offers a winning solution for open high speed
networking. Applications can now run at full FDDI speed, 100 megabits
per second. The combination of Alpha AXP workstations, the DEC
FDDIcontroller/TURBOchannel network adapter, and DEC OSF/1 Operating
System software represents a signification price/performance
advantage for users. This white paper describes details of these
system components and explains how each one affects overall system
performance. Performance measurement results are also provided. The
system components include:
- The world-class Alpha AXP workstation series
- A new low-cost FDDI network adapter
- State-of-the-art OSF/1 operating system software with
BSD 4.3 Reno TCP/IP

| 963.4 | OpenVMS was sighted flying at 170 Mb/s on FDDI | MUDDY::WATERS | | Thu May 27 1993 16:36 | 15 |
| The folks who set up the network demos for DECUS report the following
tidbits. These people were not intentionally benchmarking the systems
for publication, so our best speed may be better yet.
Using a DEC 4000/620 with two DEFAA Futurebus+ FDDI controllers, a
VXT 2000 X Window terminal, OpenVMS AXP V1.5 and TCP/IP Services for
OpenVMS V3.0, they report two bricks demos running over UDP/IP to
two DEC 3000/500 workstations at over 170 Mb/s, and over 105 Mb/s
using TCP/IP.
Between the two DEC 3000/500 workstations with one DEFTA FDDI apiece
and DEC OSF/1 AXP V1.2, bricks runs at full FDDI speed over either
TCP/IP or UDP/IP. This has been reported before.
Bricks traffic was flowing through a GIGAswitch for these measurements.

The network at Spring DECUS '93 in Atlanta
The DECUS network is an extended LAN consisting of multiple ethernet segments
bridged to an FDDI backbone. The backbone FDDI ring and several dedicated
FDDI rings are connected by a GIGAswitch.
Network components are housed in a Master Distribution Frame (MDF), located
in the Networks booth, and in six Intermediate Distribution Frames (IDFs)
distributed around the DECUS exhibit floor. IDFs are cabled to the MDF in
a star configuration.
The MDF contains a GIGAswitch, two FDDI concentrators (DECconcentrator 500s),
and two FDDI to Ethernet bridges (DECbridge 620s), connected in a dual ring
configuration. IDFs contain one FDDI concentrator, one or more DECbridge
500s or 620s, a terminal server, and LAN Bridge 100 operating as a LAN
traffic monitor. The GIGAswitch, concentrators, and bridges in the MDF and
IDFs form the show backbone FDDI ring.
DECUS systems configured for FDDI are cabled directly to the concentrators
in the nearest IDF or the MDF. Ethernet systems are connected to one of the
ethernet segments created by the DECbridge 500s and 620s.
Additionally, in the Networks booth, there are two racks containing DECNIS
routers. One DECNIS is connected directly to the FDDI ring ... it operates
as the designated router for the network, and provides wide area DECnet, OSI,
and IP connections. The other is connected to an ethernet segment and will
be used to demonstrate new DECNIS down line loading and management features.
GIGAswitch/FDDI demo
Also connected to the GIGAswitch is a DEC 4000 Model 620 AXP departmental
server and two DEC 3000 Model 500 AXP workstations.
The DEC 4000/620 has two DEFAA Futurebus+ FDDI controllers, and each controller
has a dedicated FDDI connection to the GIGAswitch. The 4000/620 is running
OpenVMS AXP V1.5 and TCP/IP Services for OpenVMS V3.0. Serving as a "console"
for the 4000/620 is a VXT 2000 X Windows terminal. The VXT will be used to
show Out-Of-Band management (OBM) on the GIGAswitch, MCC management of the
GIGAswitch, bridges, and concentrators, and the bricks demo described below.
The two DEC 3000/500 AXP workstations each have one DEFTA FDDI controller and
a dedicated FDDI connection to the GIGAswitch. The 3000/500 workstations are
running DEC OSF/1 AXP V1.2. They will be running the bricks demo.
The bricks demo is an FDDI performance demonstration. We can demonstrate
the DEC 4000/620 sending UDP/IP at over 170Mbps thru the GIGAswitch to the
two DEC 3000/500 workstations. Alternatively, TCP/IP can be sent at over
105Mbps. Any of these systems can be shown sending TCP/IP or UDP/IP at full
FDDI speeds. Full duplex FDDI can also be demonstrated.

| 963.7 | I haven't run bricks of DECnet/OSI on AXP - yet | JEDI::CAUDILL | Kelly - NaC Tech Support - 264-3320 | Fri May 28 1993 11:27 | 10 |
| re: .5, I have great faith in the DECnet/OSI performance, but I have
not been able to spend the time to try it - sorry :-(
I have lots of excuses... DECnet/OSI for OpenVMS AXP field test kits
were not available until too late in our staging schedule... I did not
want to have DECnet/OSI on the OSF systems and not the VMS system - not
that I care too much about being fair, I just didn't want that
difference to take attention from the performance demo and the GIGAswitch.
Maybe next time (ie Interop).
