Hello Folks,

I'm setting up two new servers on our network.One will be a terminal
server
for SQL, the other will hold the SQL database. We have cat5e
cabling,100mbit
switches now. A friend suggested hooking the two new servers and the DC
to a
gigbit switch (he calls it a backplane),

It is not really a "backplane". The backplane is the internal part of the
switch used to interconnect all the switches ports. Traffic going into a
switch
port crosses the backplane to get to the next port that it is going to go
out
of. So it doesn't really apply to what he is saying. The correct term
would
probably be "backbone" which is the Layer2 network segment between the
switches
themselves which may also include LAN Routers. It is synonymous, or at
least
overlaps, with what is known as the "switch fabric". There are no
"computers"
on a properly designed "backbone".

to my 100mbit 3coms. So even though all the clients are still
on 100mbit, he says having just the servers tied to this gigabit switch
will
be beneficial. I don't really get the concept.

There is nothing wrong with doing that, and is generally a good thing to
do if
you have the money to do it. But there is no measurable benefit unless
there is
a lot of traffic moving directly between the servers themselves, and I
don't
see that happening there. It doesn't make much different between Clients
and
Servers.

Terminal Servers are "low traffic" because it is just screen
updates,..that's
why they are great over slow links. The DCs are always "busy" but it is
not a
heavy load,...it is a low or medium load although it is somewhat
constant,...so
being "busy" doesn't always mean "heavy", it depends on what the content
of the
traffic really is. The SQL Server has the potential to create a lot of
heavy
traffic,..but that depends on the nature of the Application using the data
and
where the Application is physically located which determines the physical
path
the data has to take.

Also keep in mind that a Gigabit link that is "acting up" due to a problem
can
end up being slower than a 100mbps link that is functioning properly.

Phillip,
Thank you.Your explanation reflected my intuition when the consultant was
"explaining" it. I'm self taught. As a result, on occasion I hire
consultants. I know that NO single person
knows it all, no matter how much you pay. This person has knowledge in more
than a few areas I do not. When semantics in an area I know a bit about
aren't quite correct it disturbs me, I just don't know how much I can trust
their opinions after a certain point. I "caught" him in a couple situations
similar to this. He does have an agenda, as he also
consults for the company that writes our practice managment software. Geez
who do you trust nowdays? Thanks for the knowledge,Adythemic
