As I have left out some data and made a mistake with network, I'll try
to correct my post here:

Of course we are using Gigabit Ethernet, as Philipp Sadleder noted.
And at the moment we are running one pvfs2-server per node, and on the
same nodes two b_eff_io processes per node.
However we will run a 5 IO-Node/5 Compute-Node-Configuration later.
