The Intel switch is about $550, the Mellanox about $100 more and with 2 ports. That is not to bad and the Intel at least appears to have been supported by Linux and FreeBSD for several years, which is a good sign. I now need a small switch. Are there any 8 port dumb 10gBase-T switches? I can only find 24 port switches for >$15,000. I can find a few gigabit switches with 2 10 GB uplink ports - that isn't any better than a crossover cable. But nothing with 4 or 8 ports. Any ideas? Thanks again. Daniel Feenberg
