Have you done testing with 1Gb networking? Do your storage boxes have enough

You'll need some pretty fat storage nodes to justify going to 10Gb.
Actually, we have picked up all our 10 gig infiniband gear on ebay for an
avg of $1K for a 24 port switch, $35 for dual port cards, and $20 for
cables. At that rate it has been easy to justify 10 gig infiniband. The
latency improvements are significant.
