[kwlug-disc] The sweet(?) smell of power supplies

If price was no obstacle, one could build a reasonably portable 8TB
system that ran on 150W or less.

If that is not the case, then the odor-free client + remote server route
probably makes for sense.  If you can route a length of 10GbE fiber
between the two, performance could be better than having everything in
one box.
