In a Datacenter, best practices are to have servers with dual power supplies, each going to a seperate PDU, which goes to a seperate circuit, which is powered by a generator, and cleaned by a UPS.
So many things can go wrong, from sysadmins plugging the dual power supplies into the same PDU, to the generator failing to kick on.
