Anthony,
There can also be performance concerns when routing between 16mb token
ring and 100mb Ethernet. Some TCP/IP stacks default to very small
packets if they discover a router in between the network segments. This
was a major bottle neck for us until we got all the ADSM clients onto
100mb Ethernet.

Thank You,

                Hi Anthony!
                It's a customer requirement.
                I have one (important) customer with two completely
separate FDDI rings. He
                wants no single point of failure, so I have to offer him
two FDDI
                connections.
                The standard in our shop is 100 Mb. Ethernet, so I need
this connection too.
                The older clients (Token Ring) I can route through
Ethernet, but in that
                case I still need 3 adapters in my server...
                Kindest regards,
                Eric van Loon

                Why so much hardware.  The cost effective way, would be
to have the
                connection from the ADSM server to the network be of one
type and have
                routers and switches funnel the data from the others to
the ADSM server.
                Adding multiple nics of so different topologies will do
nothing but slow
                your server down trying to process them all, it you can
get them to work
                together.
