Although the buildings are on the same campus (multiple buildings about 8
total that we occupy and only parts of building for most of the buildings)
we don't have control over the network. That is in the hands of the campus
IT organization and they like things done a certain way. We can light some
fibre, but it's only point to point and we don't have that much fibre
running to our building to connect all the buildings, plus the expense would
be astronomical as we can't tie into their network and so connection in the
other buildings would be limited. Since they are finally deciding to upgrade
the core switching to 10GbE, they are possibly putting our building on the
list to get a 10GbE link first. I think that would alleviate the biggest
part of the problem, as we suspect that most of the storage will sit idle
and not really accessed. Since all the desktops are only running 100 Mb
connections, it gives us enough concurrent connections that we
feel comfortable with.
