You might be thinking of Halons, which are CFCs that depletes the ozone layer? They are mostly phased out worldwide but existing installations might still be in use.

FM200 is something else that is often used in modern builds (not just datacenters).

I've heard that one. I thought it mostly affects refrigerants, but I didn't notice that FM200 is also an HFC. There are other fire suppression gasses with a low global warming potential, which probably can still be used in the future.
