[dc-ops] General opinions about AC cooling..

[Michael Balasko]

So like someone said, it depends.  Depends on power densities per rack, the outside climate, what your goals are etc. With lame disclaimer in place I do know that hot aisle containment is the way to go. Overhead is king, and underfloor is like AM radio, decent and will run be around forever but if you can do the overhead option(FM) that is the way to go.

Take a peek at the book of faces open compute stuff for ideas -

and the guys that are REALLLLLLYYY Doing it right.

Coincidence, n.:
  You weren't paying attention to the other half of what was going on.

What do you guys think about ditching crac units and raised flooring?

We’re still in the planning stages of building out a new Data Center.
Since we are going for a Busway system for power, the only need for raised flooring would be AC units.
We talked about doing in row AC units, but are now leaning more to redundant commercial units, like Trane 30’s.
Mainly the reason being outside air economizers, and other options that can be built in from the factory.
I would guess as long as the filtration is good, there shouldn’t be any issues with the halon system or particles.

I don’t see any issues with this setup, but would like to hear opinions from both sides if possible.
