I may be out of place saying this, and I by no means intend to start any
sort of flame war,

BUT, I feel that you have done Robert Brown a great disservice in your
attack below.  He has been a consistent and excellent contributer to this
forum, and I doubt he intended any "supercomputer elitism."  He is far
more likely to abhor such elitism.

I believe the intent of his statement, is that beowulfs focus on
computational performance - rather then high-availability.  (That is not
to say that the two focal areas do not over-lap.)  IIRC, RB has even
championed the single-image cluster at various points in time.

His comment does not slight data and web server clusters - just points out
a different focus.  Most beowulfs, due to budget constraints, etc., do not
provide for redundant power, high perf. RAID arrays, etc. that would
typically be desirable for production data/web serving clusters.
