The number the developer gave in a press release was "20-30." I find that reasonable as a very large Facebook data center near me has a permanent staff of around 50. Keep in mind that these large DCs use contractors for the majority of the work, which unfortunately doesn't really help with employment because the contractors mostly come in from out of state (there is a HUGE temp labor market for traveling IT technicians and skilled crafts get hired mostly from big national outfits that just send whatever crew is available next). It is good for the hotel business though.

You have no idea how much maintenance is required. Just replacing hard drives, not even counting server repairs, new servers installation, network infrastructure installation and maintenance, power distribution, generator engineering, water treatment etc etc

And that's all stuff that they bring in out of state contractors for. I know, it sounds odd, but this is pretty normal for any large industrial site.
