To all:

I know I've asked this question before, but it was some time ago (last year
sometime), and the response was rather small (because nobody was really
doing what I was asking about). But I believe with the recent introduction
of some of the more intelligent NICs out there (General Signal's LINK/9000
and FileSpeed from CNT for instance), there may be more people who are
employing this technology with ADSM.

The network folks have decided (wow! a decision was actually made) that
ADSM should have its own dedicated backbone (probably 100 Mb switched
Ethernet). As such, the need for dual NICs in each of the clients becomes a
reality. Assuming that each client has available slots for a 2nd NIC
(always a question with older clients), and that the network can be built
in a reasonable amount of time (out of my control), am I correct in telling
these people (1) that ADSM has no control over what NIC is used (I've never
seen anything in the documentation or on any screen for control designation
for a network card); (2) that the controls used will have to be configured
at the time that the 2nd NIC is installed and discovered by the existing
client; and (3) that as long as the NIC is correctly configured for ADSM
traffic only (assuming again the existence of a table or other entry that
tells the ADSM traffic here's where you go if your destination is
such-n-such), that ADSM traffic will indeed by routed through that specific
NIC and down the dedicated wire? I have a funny feeling that the network
folks think that ADSM will be driving when the data traffic starts
streaming toward the ADSM server, but I don't think they realize that
they've got to provide the track on which it travels first as well as the
road signs.

Thanks much!
