Well, ORNL presented a paper at ISC a few weeks ago with an implementation
of data mirroring that might be similar to SNS. I haven''t seen more
than
the presentation about it yet, but I''ve asked them to post the code to
lustre-devel so we can all look at it.

We''ve tested Hadoop running on Lustre, and in some workloads Lustre is
much faster than the HDFS, but not in all of them. It was just a test,
and we haven''t done much to optimize it.
