I'll give it a try and see what happens. The thread was sort of lost :). I was 
hoping to find some ideas on tuning the OS itself, not just NFS.

I only have the one server up right now, I am currently trying to pull all of 
the pieces together to build my first multiple server xen setup. So, I'm still 
flexible and listening to input :).

Good, I didn't misunderstand something in that idea then.

I've been collecting hardware for a while, I just happen to have lots and lots 
of exactly these things :).

Seriously, I'm just a small developer, who acquired a great deal of hardware 
over the past few years playing with various technologies. I didn't become a 
pro at any one of them but learned a lot of basics and conceptual ideas. I am 
hoping to put this experience to work by building a highly reliable setup that 
can not only handle some redundancy, but more important, actually be somewhat 
easy to use, expand on, etc.

I got myself into a business once where the growth was very fast, we could 
never keep up and our technology was changing so fast, we needed more power, 
constantly so it ended up being a nightmare of multiple days awake at a time 
and too much down time because of the constant changes. I'm hoping to get 
things right, as much as I can, up front, so that doing something serious with 
this doesn't turn into that nightmare again.
