[Beowulf] More about those underwater data centers

[Stu Midgley]

I refute both these claims.

You DO want to run your boards immersed in coolant.  It works wonderfully
well, is easy to live with, servicing is easy... and saves you almost 1/2
your power bill.

People are scared of immersion cooling, but it isn't that difficult to live
with.  Some things are harder but other things are way easier.  In total,
it balances out.

Also, given the greater reliability of components you get, you do less
servicing.

If you haven't lived with it, you really have no idea what you are missing.


Serviceability is NOT challenging.
