I would appreciate seeing the specs you came up with as well but don't need
to particularly quickly.  I'll wait until seeing the PR to comment on the
specifics, but have some questions about the thought process that went into
configuring the hardware.

Is the idea to see how you spec'd out memory/disk/processor for each
physical machine?  How did you optimize the ratios between the three for
Spark specifically?  Were you able to test this configuration against
others to optimize for price per performance?

Sorry for the barrage of questions -- I know talking hardware tends to
bring out the crazy in people.
