Our server room is a converted closet, and we have a pair of wall-mounted air conditioning units to cool the room. These are both pointed towards the front of the server racks, and there are a couple small vents for hot air. We definitely don't have an ideal environment, but it's what I'm working with.
My question is related to an ionization feature of the A/C units. I know that this feature will basically spit out negative ions that attach to dust and other particles, and make them heavy enough to drop to the ground. With this basic understanding, I am trying to figure out if it is better for a server room to have this turned on or off.
I would imagine turning it on would mean purer air, which would mean the intake of air to the servers would have less dust (ie, good to turn it on).
However, I could also imagine that the ionized air would contain bigger, heavier dust particles that would normally drop to the ground, but could get sucked up into the servers because of the air flow. This would lead to bigger dust particles in the servers, which would be more likely to cause issues (ie, good to turn it off).
I haven't found much looking around online, so I'm hoping that someone out there might have done some deeper research into this already. Or, hopefully someone can factually show me that I'm considering something that is so minor it won't make a difference.
