Now days people often put on hearing protection before for going into
the racks.
Nobody I know does that, and I certainly don't.
The density is so much greater now though. It is
insanely
loud. I just look at these pictures and wonder how it compares. That is
still a lot of fans and machines grinding away. Everyone always looks so
calm and like it isn't in the pictures though. Looks like they can talk
normally and not have to scream.
It is definitely different now. We went from a small number of very
large machines (with large-diameter, slower-turning fans) to a very
large number of very small machines (with tiny, screaming high-pitched
fans).
Now of course, with virtualization, the pendulum is swinging back the
other way, at least somewhat. I'm seeing fewer and fewer 1U machines in
racks, and more and more 3U-5U machines in their place, each replacing
twenty or thirty of the 1U machines.
And they have bigger slower-turning fans. :)
