[OFF-TOPIC] 4 ports ETH cards

[OFF-TOPIC] 4 ports ETH cards

[Fabbione]

Hi all,
	sorry for the offtopic msg.

Can someone point me to a 4 ports fast/eth card solution for linux?

I found some cards based on the DEC 21*4* chips but when
I asked for more details I got a strange answer from the reseller
like that this card is able to work only half-duplex and the chip has
only one mac-address for the 4 eth cards (really strange).

Thanks a lot
Fabbione

Adaptec has the DuraLAN product (aka starfire). Look in their web page.
Drivers are included in the kernel; for more info, look in:

This sounds like it's not a 4 port card, but a 4 port hub-card. (Eg a card
with integrated 4-port hub)

Hi Dan,
	yes it's more or less like this. I got many mail explaining me.
I will forward the most interesting to you.

Thanks

D-Link DFE-570 has a reasonable pricing and is well supported by the 
tulip driver

nah. And even if so, you can always change the mac-address using ifconfig.

What the guy most likely wanted to say, is that there is only one EEprom
containing all mac adresses for the four tulip chips, which I have seen
on multiple boards

	Just got three of these suckers and I'm about to order a bunch
more (happy camper)...

	Each D-Link card has four MAC addresses (sequential).  I doubt
other manufactures are any different.

	What the guy was doing was having a bad case of optical rectitus.
That would be typical of a "reseller" (AKA Salesman).  Most would not
even have a CLUE that the cards were based on the tulip chipset / driver.

	Because the D-Link cards were less than half of the nearest
competitor [ < $180 vs > $360 for others and Compac was > $2400! ] I
ordered only three not knowing for sure if they would work.  Turned on
the tulip driver and them suckers fired right up.  Now I know they work,
stock, right out of the box, and I can order a bunch more for the lab
I'm working with.

I've been working with these boards for a couple months and thought they
were great.  However, now it turns out that they won't fit into our
systems too well (a little too long).  Does anyone have knowledge of
another brand that has a (slightly) smaller form factor?  I did some
checking on Pricewatch but wasn't able to find anything that fit our
needs.

TIA,

-Jeff

The Adaptec Quartet64 boards worked ok for me with 2.2 and the Starfire
driver.  Not sure if they are smaller (shorter) than the D-Link but they
sure are a lot shorter than the old Tulip-based Adaptec quad boards. They
are a bit pricey, though.

yes the Dlink DFE570-TX is a very nice card indeed.

I use those cards in all routers here and they work extremely well.
But I don't use the standard vanilla tulip driver that's in the official
kernel. I use an optimized version that handled high traffic volumes much
better, it decreases the interrupt-load quite a lot. (this driver is about
to be merged with the standard tulip driver IIRC)
I havn't had any problems with these cards so I can really recommend them.

[Fabbione]

First of all I would like to say thanks to everyone.
I didn't expect so many answer in so few time ( I got
most of them directly in my mailbox)

Anyway I've ordered right now the D-Link DFE-570 that
seems the one with the best price/quality ratio so I
can test it on the "battle field".

Best Regards
Fabio

I have to comment on this one, the Compaq cards (NC3131 and NC3134) are ~$210
and come with two ports, upgradable with another 2 port module (daughterboard)
you have a choice of 2 more 100mbit ports ($233) or 1 gigabit port ($500),
perhaps you were under the influence of drugs, or the salesperson was.
(btw, it uses the eepro100 driver, which, in my experience, is very stable.)
