Isn't the 3 Com 509 a 10Mbit card? How did you get the 3 Com 905B to work? Do you realized that 300 GB/day is equal to 27.7Mbits? How many systems do you have serving 300 GB/day through that 100Mbit switch? A good quality 100Mbit switch is only good for about 80Mbits before you start getting too many colisions to get any packets through. So, if you've got 3 systems running at that speed on one 100Mbit switch and you're having problems with reliability, I'd take a look at the switch rather than the NICs. Terje Oseberg http://www.reactor-core.org/~oseberg : Greetings, : : We have several very-high throughput boxen (>300 GB/day each) : sitting on an Arrowpoint CS100 switch. Our problem is that at these : sustained throughput levels, our NICs just crumble :-( : : We've tried : 3 Com 905B (garbage) : 3 Com 509 (so-so) : A variety of Realtek based TX cards (slow...) : and a DEC 21140 based card (great when it works, but seems to : crap out at the high end of the traffic curve) : : FreeBSD handles some of the highest loaded sites in the world, : so I *know* it can handle it with the right NIC. My question : should be obvious: what NICs do the readers recommend? : : Thanks! : : J.A.
