HPC and zfs.

Is there not likely to be a degradation in performance while doing the backup? 

...which ties into something that I think is missing from this thread: a statement of what this massive 
pool of storage is going to be used for. "HPC" is a pretty broad term, and isn't quite a specification in 
my book. 

I have faith that the relevant BSD technologies can be cobbled together to get OP to the performance
level he needs, but -- and perhaps I have failed basic reading comprehension here -- I don't think we 
have a clear enough picture of what that level actually /is/ to offer advice on what is almost certainly
going to be a multi-million dollar installation!
