IIRC the docs had some very high CPU requirements to support "high speed" network interfaces - I seem to recall something like one CPU per 100 Mb/sec interface on U1/U2-era machines... Made me wonder where people were deploying those QFE cards...
>As I mentioned before, I have a fiber GigE SBUS card for COS if anyone
I dont' want them, but I am curious what it would take to make use of them - obviouosly cards & fiber cables, but it a switch needed? some other technology? and how are the cards configured - is it like an Ethernet connection to the software, it just travels over different media?
I've (obviously) never tinkered with fiber before, but I'm thinking I might want to get a handle on the technology...
