That might help you out with the front end (exporting iSCSI devices 
onward), but from what the front page says, it doesn't look like it's 
going to set you up with the storage aggregation part. I could be wrong, 
though, I haven't had a chance to go through all the docs for OpenFiler 
yet.

It'll use it as required unless they run out. It depends on your CGIs, 
Apache itself will always be quite light. If you have lots of requests 
being processed at any one time, lots of CPUs will help. If you have lots 
of CGIs requiring memory, it'll use the memory. The only way you'll find 
out is by throwing the expected mix of requests at it and seeing what it 
uses up first.
