Servers with dual power supplies being fed from different phases/ups

    Are you saying you have two redundant PDUs? If so, feeding each power cord from seperate PDUs is a more reliable approach to powering dual corded equipment. If you only have one PDU, then the next best thing is to feed each power cord with a different circuit. As for which phase to use, it absolutely doesn't matter as long as the three phases are loaded in a balanced manner.

    You may want to read a good white paper on this topic: Comparing Availability of Various Rack Power Redundancy Configurations

    Hi,

    Just a quick sinmple question!
    What are the issues with running dual fed servers from PDUs, one fed from one phase and the other fed from a second phase?

    Thanks in advance.
    Giles
