Peaks of 1MB/sec are quite common. Fair enough; that justifies a PCI card of some description. > Still no justification for the 3Com one.

I suspect that the 590 as a card is quite OK, but a number of Unices have problems with them, and the 'vx' driver isn't quite up to snuff yet. If this sytem is mission-critical (and it sounds like it is), the extremely robust and well-tested 'de' driver, and the very cheap cards that it supports are a more sensible choice. (Note to australian consumers : KTX are selling a Tulip-based card that can be had for around AU$80 ex; we now have a few of these and they work just fine.
