When will IB go optical at a reasonable price? Perhaps you are not
an expert but if you happen to have any pointers where we can learn more
about the time frame it would be useful. Just a few days ago heard
colleagues trying to figure-out the solution to connecting file system
hardware just a bit too far from a cluster in another building. Ethernet
and NFS would work but latency is a problem.
