Next, fire suppression would be a Halon system for a generator, being fuel is involved, not a water sourced sprinkler system.

There are lots of "indoor" generator installations with exhaust vented to outdoors. Most likely would be a separate room from servers, but fire alarms in simple sprinkler system can set off deluge in entire building.

Halon hasn't been manufactured since 1994. Supply is limited and decreasing - so expensive. Nobody specs new halon systems unless its a ridiculously sensitive area and they want to spend big bucks. Typical commercial server farms ain't gonna pony up the money. There are other "clean chemical" halon alternatives, but even when an area has a chemical system there is usually a backup water system since chemical systems have limited capacity and stop working when chemicals run out!!
