Re: Overall networking issue...

On Sat, 25 Oct 2008 23:47:25 +0200, Jacob Tranholm rearranged some
electrons to say:

I have the problem that I have to install a server on a larger
professional 100Mbit/s CAT-5 network (with about 100 desktop computers
connected and up to 2-300 more on wireless connections). This network
already has a well-functioning structure, where it is easy to transmit
information at speeds up to 100Mbit/s (the network works). My problem is
that I am not happy with the 100Mbit/s restrictions. The server already
has gigabit network card(s)... And I am wondering how/if it will be
possible to use the gigabit speed without having to change the basic
structure of the network. Because the network is already up and running,
I will get a hard time finding the funds to change everything, and since
100Mbit/s is sufficient in the vast majority of situations, it should
not be necessary.

What would happen if one for instance attached a standard (cheap)
unmanaged gigabit switch (eg. a D-Link DGS-1008D) for such a network.
The server for one port, and the remaining 8 ports connected to the
existing 100Mbit/s network (we can find 8 vacant ports in the existing
structure). Would this give any increase in network speed with the
possibility of 2 (or more) computers at the same time being able to use
the data from the server at speeds closer to the 100Mbit/s. According to
benchmarks the server can read and write the data quite a bit faster
than required by a gigabit connection.

I apologize if this is an absolutely ridiculous question. My hands-on
experience with this aspect of larger networks is unfortunately limited,
and therefore I hope for constructive advice from you.

Unless you replace all the client NICs with gigabit-capable units, and
any switches or hubs with gigabit-capable units, nothing will be any
different than it is today.
