what is the best way to isolate the power issue in the server room . we had a downtime due to one phase trip has went off due to unknown issue . we have two UPS and getting the power to the server room , but at the end it seems be the same power source . when the trip went off entire data center out of service . is there any way we can get the alarm in case off one phase went off or UPS issue ?
please share the best wary to design our new server room (data center)
