2010/7/14 William Warren hescominsoon@emmanuelcomputerconsulting.com:
I think it's baloney mainly because i can't find a mention of it
anywhere. Is there REALLY a limit on the number of
physical network
interfaces in the Kernel?
can you really create hardware with huge number or real ethernet controllers?
13x4 = 52 ether chips is possible with COTS hardware.
Even if the limit were lower, such as 10 physical interfaces as mentioned before, I have to imagine that the host system would have issues dealing with the number of interrupts needed to *PROPERLY* service all of those interfaces in addition to the other system hardware. They may all work, but your performance may be horrible. In that case, I would think one or two 10Gbe interfaces to a nice switch and the necessary VLANs would perform nicely.
Just my $0.02 USD.
