cheap 4-port tulip-based cards available

cheap 4-port tulip-based cards available

[Jason Lunz]

I figure a few people on this list will be interested in this:

http://www.softwareandstuff.com/h_comp_inet4.html

The site says almost nothing about the cards, but on a tip from a
coworker I bought one the last time this site had them for sale, and
have been extremely happy with it. lspci shows:

02:04.0 Ethernet controller: Digital Equipment Corporation DECchip 21142/43 (rev 41)
02:05.0 Ethernet controller: Digital Equipment Corporation DECchip 21142/43 (rev 41)
02:06.0 Ethernet controller: Digital Equipment Corporation DECchip 21142/43 (rev 41)
02:07.0 Ethernet controller: Digital Equipment Corporation DECchip 21142/43 (rev 41)

This card is similar to the d-link 570-TX, though it actually seems to
be of higher quality when you have it in hand. Rumor has it that a bunch
of these cards were made for a dot-bomb company and they're now just
surplus.

anyway, knowing the problems people are having with the sundance 580-TX
and the unavailability of other cheap 4-port nic options, i though I'd
let folks here know. A good 4-port tulip card for $30 is a nice deal.

sorry for the spam.

Bastards won't ship out of the U.S.A. if the order is less than $500.
I want 2 cards, not 17 :-(

Indeed. Pity about the shipping restriction, though.

These are the Phobos p430 NICs.  I have extensively benchmarked 2
of those NICs that I got as eval copies, and they perform as good
as or better than the 570tx, using the standard tulip driver.

I just noticed lots of these are on eBay too, so I'm guessing a whole
bunch of them got surplussed.  This is good news for me, because they
are too expensive if you try to purchase them from other channels!

I'm just curious. What do you do with a bunch of those cards? Do you put
them in a PC and make a switch out of it?

cheers,

Or a firewall...  Or a router...

OK, I actually have 4 nics in a PC based router/firewall. But I wouldn't get
excited about buying a bunch of those cards. I'm just having a little fun--
humor me. ;)

Thanks for your comment.

cheers,

I make traffic generators out of them (www.candelatech.com)

They are also good for firewalls and routers, as well as more
exotic network devices.  Using linux for a switch does not make so
much sense these days when you can buy a 16 port switch for under $100,
but with bridging code it can be done.

Actually, I think linux based switches could be quite interesting in
a pipelined, beowulf-like or openmosix cluster. (Of course, GigE would
probably be employed rather than FE.) You could then integrate traffic
shaping/monitoring functionality into the switch that could be designed
to interoperate with the cluster nodes to assist in optimizing data flow
and subsequent processing. With openmosix, this could also be used to
migrate processes towards optimum node placement, based on network
traffic analysis as well as nodal resource availability.

It's a subject I've been thinking about quite a bit lately. This is most
interesting in adaptive, pipelined clusters that will be processing
real-time streaming data. That's certainly a niche market at the present
time.

cheers,
Karen

Right now, you'll have a tough time getting a single GigE NIC to run line
speed, full duplex.

However, I've thought about writing a controlling process that monitors
and dynamically configures a switch though SNMP or some other API.  That way,
you could migrate machines across LANs/VLANs to better distribute your traffic.

And, you could keep all your traffic running line speed (or however fast
your switches run)

I used to have a desktop PC with 3 NICs running as a firewall. With a
4-port NIC and a Via/Cyrix C3 (low profile fan), I can fit a firewall
into a 1U rackmount case. So, while it's a lot more troublesome
getting a stable router with these 4-port cards :-(, it's worth it in
the end if you've got space constraints.
