RE: NICs - bottleneck (was Re: Dropping the AS/400 as a Web serving platform)

Joe,

I agree with your common sense, that's why I doubled the number of machines
from 3 to 6 (No, I'm not targeting 12 9's uptime). There is no way to
achieve 0% downtime, ever.

<COMMON SENSE>
This argument implies totally redundant systems.  That means each of your
servers has to have the capability to run your entire application.  A W2K
machine with that sort of capability is not cheap.  In fact, it's comparable
to a low-end iSeries.

Whereas you can easily keep two AS/400's up and running with 0% aggregate
downtime.
