Oh no! I wasn't meaning that I was designing this. Sorry. I gave my
vendor the specs. and these were the options that came up. He is
meaning to design each component to balance loads.

But realistically for 300 compute-nodes a config. close to what I
wrote is to be expected he said. Just giving and idea of where my
current expectation is about where we will be ending up at.
