there can be some benefit to the lossless FC fabric through
eliminating TCP RTO's and applying backpressure so the initiator has
more control over I/O scheduling.

As discussed here, block-based storage can produce fewer synchronous
calls / rtt waits than NFS for workloads involving opening and closing
lots of small files when you are not calling fsync on them.  

I state both based on theory not experience, and I'm not saying that's
Gary's workload falls in the second category, nor that NFS is
necessarily the wrong approach, but here are two reasons a sane person
might plausibly decide to use the LUN interface instead.  I'm sure
there are more arguments for and against.
