A while back I asked about the differences between the 170 and 170E. Here
are the responses I received back. Thanks much to all who took the time to
answer. I'm the proud owner of a new 170 and extremely happy with it. I've
posted my original question first.

The difference between the 170 and 170E is 3-fold.
1- fast-wide SCSI on the E vs fast SCSI
2- fast ethernet (100Mb/sec) on the E vs ethernet (10Mb/sec)
3- 2 sbus +1 UPA on the E vs 3 sbus slots
If the ethernet's gonna be full, a 170 might be a bit light on horsepower for
five of them, but if they're light traffic, it could work.
Also, I think the 170's are phasing out in favor of the 200's (same deal but
you may be happier with a 1200 which has more slots and a socket for a second
Hope this helps

You need to find new consultants....
Neither has upgradable CPUs. Only the Ultra 2 and above modular
CPUs. A CPU upgrade on the Ultra 1 series requires a motherboard
The difference between the 170 and 170E is that the 170E has
fast/wide SCSI and fast ethernet and a UPA slot for the video
card (to support Creator graphics).
From: Systems Admin <email@example.com>
Did the consultant mention the Fast/Wide/100Mb ethernet that the system comes
with? I'm sure about the fast/wire but not about the 100Mb. Actually for a
firewall thats over kill. I've been involved in the development process of
a firewall package and did a lot of monitoring.

the difference is the FFB-UPA-Slot. With the E-Version you can
insert a Framebuffercard (3-D Graphics) without the E you are not
able to do so. When you look on the back of the box to the connectors
you can see above the parallel connector a slot, it is a ffb-upa if it
is a 170E, it's normal sbus at 170 model.
170E -> FFB-Slot CAD...
170 -> normal Sbus-Slot

The Ultra 1 can't have it's CPU upgraded. Only the Ultra 2 has replaceable
CPU modules. The difference between the 170 and 170E are as follows:
The 170 only supports Sbus graphics cards, not the Creator series.
The 170 has 10Mb/s on-board ethernet, the 170E has 100Mb/s.
I also think that the SCSI on 170 is ordinary fast SCSI, while 170E is
fast and wide (20 MB/s).
the only difference i know about those machines is that the 170 has 10MBit/s
Ethernet and Fast-SCSI, the 170E has 100MBit/s, Fast-Wide-SCSI(!) and an
UPA-Port for the creator graphic series board (creator 2D/3D). I don't know
anything about swapable CPU-Modules, but I think you can do this on both
If you don't need monitor and keyboard, you could order the machine without
them. Or take a look at the enterprise 150. It's a server machine and comes
in a special cabinet.

170 does not have the 10/100mbs ; it's only 10
does not have a UPA port ; much faster port for video
The monitor & keyboard are only distingished by whether you specific the
workstation vs server (server does not come with monitor & keyboard nor

The only difference between the 170 and the 170E is that the 170E has a
Creator graphics card. Since you won't need video at all, I suggest
getting the 170.
170 == TGX framebuffer (8bit)
170E == Creator framebuffer (24bit)

My understanding is that the 170 comes with FW SCSI
and the 170E comes with UW SCSI.

These are quite reliable machines, we had one which ran 3 different
Oracle 7.1.6 database instances simultaneously with NO problems.
Here are the comparisions of the 170 to the 170E:
Component/Item 170 170E
# of Processors 1 1
Max Memory 1GB 1GB
SCSI Bandwidth 10MB/sec 20MB/sec
SBus I/O Slots 3 2
Graphics (UPA slots) No 1(83MHz)
Serial Ports 2 2
Audio 16bit 16bit
Twisted-pair Ethernet 10Mbit 10/100Mbit
ISDN/FDDI and ATM optional optional
Graphics Options TurboGX,TurboGX+ creator/creator3D

Ultra 170 and Ultra 170E both share the same architecture, in terms of
internal paths and processors. They differ in the graphical board and in
the output interfaces.
Ultra 170 Ultra 170E
graphic board TGX / TGX+ Creator / Creator 3D
SCSI Fast SCSI 10 MB/s Fast&Wide SCSI 20 MB/s
Ethernet 10 Mbps 100 Mbps
Slot 3 SBus 2 SBus + 1 UPA
I hope this can help you

The main difference is that the 170E has Creator Graphics 3D Buffer
Graphics which makes the unit cost much more. You do not need this for a
firewall. The 170 will be fine. It only has one processor running at
167 MHz. You would need to replace the clock board if you changed the
speed of the CPU.
From: Karl von Jena <email@example.com>
There are a few important differences between the 170 and 170E. The Ultra1
includes 3 S-Bus slots and 1 UPA slot. The UPA is a high-speed proprietary
expansion slot that I've only ever heard being used for the Creator
Graphics monitor controller card.
The 170 comes with 3 S-Bus slots, with one used by the TGX or other
graphics adaptor (which you'll need for the monitor switch, unless you're
hooking up to a dumb terminal via serial port). It also comes with 10Base-T
ethernet and Fast SCSI-2 connectors on the motherboard.
The 170E replaces the ethernet and SCSI with a 10/100 ethernet and
Fast/Wide SCSI-2 connectors on the motherboard and puts a creator graphics
card in the UPA slot (which obscures one of the S-Bus slots, no big deal
since there is only 2 free in the plain old 170).
I don't believe that you can upgrade the CPU in the Ultra1 models. I might
be wrong, but I thought that the only upgrade path for the Ultra1's is to
swap the whole unit.
Hope this helps.
