@gskger yeah same on my place. I play around with xcp-ng at home, where this is not important, and there is no UPS. So it is not important here.
But I have built two hosts at work in a server room as well. Together with TrueNAS and a couple of other things. The APC UPS has a management card, so it can be reached via network, but somehow the hosts have to shut down gracefully if needed. That's how I stumpled upon this thread in the first place.

@olivierlambert in simple words: they just don't shut down. And if they would have to there are bigger problems to solve.
Thanks for answering...

@olivierlambert I wonder how datacenters are doing this then in case of power loss? Or isn't that something of their concern?
