Thanks! I guess  I have not faced the problem that you describe (yet).
My problem is still easier. It is convincing *myself* which is the
right solution. Or more of " how to compare various vendor solutions?"
It was easy for the compute nodes. But the storage and backbone are
still not clear (to me).

One of the reasons is that it is easy to buy several compute nodes
piecewise and test the actual codes. But how does one simulate scaleup
for estimating performance of switches and backbone. Of course, over
the past weeks several useful suggestions have been offered but I am
still not sure.

Perhaps I am just not doing my homework! :)
