Hi Glenn,

Can you give a little more information?

 From the above, the cluster compute nodes and storage nodes will all  
have Myri-10G cards. The head node will not.

You want a PVFS2 filesystem for storage for this cluster. Do you need  
to access that storage outside of the cluster as well? Is only the  
head node accessible outside of the cluster or all the storage nodes  
as well?
