It would be difficult to believe that 10Gbit Ethernet offers better 
bandwidth than 56Gbit Infiniband (the current offering).  The swiching 
model is quite similar.  The main reason why IB offers better latency 
is a better HBA hardware interface and a specialized stack.  5X is 5X.

If 3xdisk raidz1 is too expensive, then put more SSDs in each raidz1.
