This is somewhat different from IB or FC "miniature networks", some/most of 10GbE testing runs in existing datacenters or over existing long-haul links - see for example http://sravot.home.cern.ch/sravot/Networking/10GbE/LSR_041504.htm Cheers, Leonid > > And if that is the case, we're talking about a much smaller > market (but perhaps a more profitable one ;))... > > thanks, > Nivedita > > > - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
